xvi Introduction
Color terms and concepts such as “RGB data,” “color space,” “spot color,” “gamut,” and “source profile” are used throughout this manual. If you are new to desktop color or if any terms are unfamiliar, be sure to read Appendixes A and B or check the glossary.
This manual is part of a set of Fiery X3e documentation that also includes the following manuals for users and system administrators:
• The Configuration Guide explains basic configuration and administration of the
Fiery X3e for the supported platforms and network environments. It also includes guidelines for setting up UNIX, Windows NT 4.0, and Novell NetWare servers to provide Adobe PostScript printing services to clients.
• Getting Started describes how to install software to enable users to print to the
Fiery X3e. Specifically, it describes installation of PostScript printer drivers, printer description files, and other user software provided on the User Software CD. It also explains how to connect each user to the network.
• The Printing Guide describes the printing features of the Fiery X3e for users who send jobs via remote workstations on the network.
• The Job Management Guide explains the functions of the Fiery X3e client utilities, including Command WorkStation ™ , and how you can use them to manage jobs.
This book is intended for an operator or administrator, or a user with the necessary access privileges, who needs to monitor and manage job flow and troubleshoot problems that may arise.
• Release Notes provide last-minute product information and workarounds for some of the problems you may encounter.
xvii Key features of ColorWise
Key features of ColorWise
ColorWise ® is the color management system (CMS) built into the Fiery X3e and designed to provide both casual and expert users the best color output for a variety of purposes. The ColorWise default settings were specifically selected to provide great out-of-box color from many applications and Windows and Mac OS platforms. This enables casual users to get good quality output without knowing about or changing any color settings on the Fiery X3e.
To get consistent color, you should be sure that the Fiery X3e is calibrated on a regular basis. ColorWise Pro Tools include a simple-to-use calibrator, which allows you to calibrate using either the scanner that comes with the copier or optional densitometer
There are a number of features that can be used to modify printing results. Depending on your particular needs, you can:
• Set the behavior of CMYK printing to emulate DIC, Euroscale, and SWOP offset press standards.
• Match PANTONE colors for the best match when printed using four-color press conditions or when printed using presses with extra, custom plates.
• Select a color rendering dictionary (CRD), also called a rendering style, for RGB printing. CRDs allow for rich, saturated printing of presentation graphics; smooth, accurate printing of photographs; and relative or absolute colorimetric rendering for specialized needs.
• Define the source of incoming RGB color data for better screen matching, and you can provide for better color conversion of RGB data with no source information.
• Define whether RGB data is converted into the full gamut of the copier/printer or whether it is first converted into the gamut of another device, such as a press standard. This feature is very helpful for making one device behave like another. It is also useful for evaluating the appearance of the RGB file under different printing conditions without having to reprocess the RGB data each time.
xviii Introduction
ColorWise offers an open color architecture, letting users customize the Fiery X3e to meet new printing needs as they arise. ColorWise supports ICC profiles, which are industry standard color profiles that define the color behavior of a device. By downloading ICC profiles to the Fiery X3e, it can simulate a custom press (or another copier/printer) as well as accurately print colors from a particular monitor or a particular scanner. In addition, you can create customized ICC profiles for the copier/ printer.
ColorWise also lets you use any Status T densitometer by importing data in a standard
file format (see Appendix C). In this case, it is important to note that the quality of the
instrument used will determine the quality of the calibration.

1-1 Managing color on the Fiery X3e
Chapter 1:
Fiery X3e Color
Management
The first part of this chapter describes the options available from the ColorWise color management system and explains how you can customize the color settings for your particular needs. It provides descriptions of the preset default settings of ColorWise and covers additional options for users who need to customize ColorWise.
Beginning on page 1-13 is a detailed explanation of what a PostScript Level 2 or
PostScript 3 printer driver does, as well as information on the capabilities of various printer drivers and instructions for setting color options with the PostScript drivers for
Windows NT 4.0, Windows 2000, Windows 95/98/Me, and Mac OS.
Managing color on the Fiery X3e
To modify the printing behavior of the Fiery X3e, do any of the following:
• Select ColorWise options for an individual print job using menus that appear from the printer driver.
• Select most ColorWise options as server defaults from Fiery X3e Setup or from the
Control Panel, as described in the Configuration Guide . These defaults will apply to all subsequent print jobs unless you override them.
• Select some ColorWise options, particularly default ICC profile settings and calibration options, from ColorWise Pro Tools. These options include default
Simulation Profile (see page 1-8), Appear in Driver as (see page 4-8), default Source
Profile (see page 1-6), and associated calibration set (see page 3-4).
Applications can generate color data for the Fiery X3e in many different color spaces .
The most common type of color data produced from office applications is RGB, while prepress applications generally produce CMYK data. Desktop applications can also generate spot colors such as PANTONE colors. To complicate matters, a single page may contain a mix of RGB, CMYK, and spot colors. The Fiery X3e lets users control the printing of these mixed-color documents with features that apply specifically to
RGB, CMYK, or spot color data.

1-2 Fiery X3e Color Management
Fiery X3e color management generates CMYK data to be sent to the copier/printer; additional processing may then be performed before printing begins.
The following diagram illustrates the print options in the Fiery X3e color management process that affect color data conversions. You access these print options when you send a print job to the Fiery X3e. Most of these options and settings are described in subsequent sections of this chapter.

RGB Source Profile is the only color option that applies strictly to RGB color data.
The other options that affect RGB color also affect the more rarely used Lab, XYZ, and other calibrated color spaces.
N OTE : For users who are familiar with PostScript 3.0 color, RGB Source Profile affects all CIEBasedABC color spaces (if the source space is RGB). Also, if you send CMYK data to the Fiery X3e in CIEBasedDEFG format, for example, by choosing PostScript
Color Management in Adobe Photoshop, the Fiery X3e Rendering Style selection— which normally affects only RGB data—will also affect this CMYK data.

1-3 Managing color on the Fiery X3e
Settings for the following options can be specified via print options when you send a job to the Fiery X3e. Some can also be set as defaults by the administrator during
Fiery X3e Setup. Settings specified via print options override the defaults.

page 1-6). To use this print option, you must choose Other as the RGB Source
setting.
Applies the specified phosphor (monitor type) information to the RGB source
space definition (see page 1-6). To use this print option, you must choose
Other as the RGB Source setting.
Applies the specified white point value to the RGB source color space
definition (see page 1-6). To use this print option, you must choose Other as
the RGB Source setting.
Determines which CMYK color space your original RGB data will be separated into—CMYK for the copier/printer (Output) or CMYK for a
specified simulation (Simulation) (see page 1-7). It is important to note that
when RGB Separation is set to Simulation, RGB colors are affected by CMYK
Simulation Profile and CMYK Simulation Method.
Adjusts CMYK color data to simulate an offset press standard or a custom color gamut defined at your site. The Match Copy setting bypasses Fiery X3e calibration to match a copy made from the copier glass. Choosing None
bypasses simulation (see page 1-8).
N OTE : Some of the Simulation settings have slightly different names depending on the model of copier/printer.

The Output Profile is applied to all data in the print job (see page 1-9). User-
defined output profiles can be downloaded to the Fiery X3e with
ColorWise Pro Tools (see Chapter 4).
The On setting optimizes the quality of black text and line art output (see
When printing separations from a desktop publishing application. Select On to combine separations on a single page. Select Off to view separations as four individual black-and-white pages each representing one color plate.
The On setting overprints black text placed on colored backgrounds; it
automatically activates the Pure Black Text/Graphics option (see page 1-11).
The On setting enables Fiery X3e matching of PANTONE colors; Off instructs the Fiery X3e to match color output to a Pantone-specified CMYK
Detailed explanations of how these and other settings affect your print jobs are provided in subsequent sections of this chapter.

1-5 Managing color on the Fiery X3e
Rendering styles
The Rendering Style option specifies a CRD for color conversions. You can modify the
Rendering Style option to control the appearance of images, such as prints from office applications or RGB photographs from Photoshop. The Fiery X3e lets you select from the four rendering styles currently found in industry standard ICC profiles.
Fiery X3e rendering style Best used for
Equivalent
ICC rendering style
Photographic —Typically results in less saturated output than presentation rendering when printing out-of-gamut colors. It preserves tonal relationships in images.
Presentation —Creates saturated colors but does not match printed colors precisely to displayed colors.
In-gamut colors such as flesh tones are rendered well, similar to the
Photographic rendering style.
Photographs, including scans and images from stock photography
CDs.
Artwork and graphs in presentations. In many cases it can be used for mixed pages that contain both presentation graphics and photographs.
Image ,
Contrast , and
Perceptual
Saturation
Graphics
Relative Colorimetric —Provides white-point transformation between the source and destination white points. For example, the bluish gray of a monitor will map to neutral gray. You may prefer this style to avoid visible borders when not printing full-bleed.
Advanced use when color matching is important but you prefer white colors in the document to print as paper white. It may also be used with PostScript color management to affect CMYK data for simulation purposes.
Same
Same
,
Absolute Colorimetric —Provides no white point transformation between the source and destination white points. For example, the bluish gray of a monitor will map to a bluish gray.
Situations when exact colors are needed and visible borders are not distracting. It may also be used with PostScript color management to affect CMYK data for simulation purposes.

1-6 Fiery X3e Color Management
RGB Source Profile
The RGB Source Profile setting allows you to define the characteristics of the RGB data in your document so that the appropriate color conversion can occur on the
Fiery X3e. Commonly used monitor color spaces are available from the driver and from the ColorWise Pro Tools Profile Manager. In addition, for special needs you can use ColorWise Pro Tools to download custom monitor or scanner profiles.
When you specify a setting other than None for the RGB Source Profile, the Fiery X3e overrides source color space definitions or profiles that other color management systems may have specified. For example, if you specified a ColorSync System Profile on your Mac OS computer, the RGB Source Profile setting overrides it. In cases where you do not want this setting to override another specified source color space, choose the
None setting.
When you specify a setting other than None for the RGB Source Profile—since the color space definitions are overridden—the prints from the Fiery X3e will be consistent across platforms. The Fiery X3e RGB Source Profile options are:
• EFIRGB specifies an EFI-defined color space recommended for users who have no detailed information about their RGB data.
• sRGB (PC) specifies the industry standard definition for a generic Windows PC monitor.
• Apple Standard specifies the definition of all standard Mac OS computer monitors.
• Other allows you to specify custom RGB source settings. If you choose Other as the
RGB Source setting, you can choose settings for the Gamma, Phosphors, and White
Point options.
• Sources 1-10 specify the definitions you download as RGB source profiles. (For
more information about downloading RGB source profiles, see Chapter 4.)
• None instructs the Fiery X3e to allow the RGB sources you defined elsewhere, such as in the application, to be used. When you set RGB Source to None, the appearance of colors will not be independent of the file type. For example, RGB EPS files will look different from RGB TIFF files.

1-7 Managing color on the Fiery X3e
With RGB Source set to None, PostScript RGB data that contains a source color space definition is converted using the CRD specified by the Rendering Style option
(see page 1-5). Non-PostScript RGB data and PostScript RGB data that does not
contain a source color space definition are converted using a general undercolor removal conversion method.
RGB Separation
The RGB Separation option determines how RGB colors (as well as Lab and XYZ colors) are converted to CMYK. The name of this option is meant to be descriptive, since the option defines the color spaces that will be used by the Fiery X3e to
“separate” the RGB data into CMYK values.
The two choices available for this option determine whether RGB data is converted into the full gamut of the copier/printer ( Output ) or is first converted into the gamut of another digital printer or a press standard ( Simulation ). This feature is helpful for making one device behave like another for RGB data. For example, if a high-quality
ICC profile is available for another print device, the copier/printer can simulate the behavior of that device.
RGB Separation is also useful for prepress applications. For example, it lets you experiment with the appearance of an RGB scan under different press printing conditions without having to convert the RGB data to CMYK data for each printing condition. When the desired printing condition is found, you can then convert the file to CMYK, if desired, using the same CMYK simulation profile that was used during the experimentation.
N OTE : The RGB Separation print option should be used in conjunction with the
Output Profile or CMYK Simulation Profile print options.
• Output converts all RGB colors into the CMYK color space of your copier/printer
(when the Output Profile option is set to Printer’s default), or a customized CMYK color space for your copier/printer (when the Output Profile option is set to
Output 1-10).
• Simulation converts all RGB colors into the CMYK color space for a specified simulation (make sure to select the desired simulation with the CMYK Simulation
Profile print option).

1-8 Fiery X3e Color Management
CMYK Simulation Profile
The CMYK Simulation Profile print option allows you to print press proofs or simulations. This setting specifies the offset press standard or other color printing device that you want to simulate. This option affects CMYK data only.
You can view up to 10 Quick and 10 Full custom simulations from the printer driver.
The number of custom simulations is limited by the disk space on the Fiery X3e.
The CMYK Simulation Profile setting you should specify depends on the press standard for which the CMYK data was separated.
• For images that were separated using a custom separation (such as a separation produced with an ICC profile), choose the corresponding profile on the Fiery X3e with the CMYK Simulation Profile setting.
• For images that were separated for SWOP , choose SWOP as the CMYK Simulation
Profile setting.
N OTE : To properly simulate a printed image that was separated through the use of an
ICC profile, the same profile must be present on the Fiery X3e. For more information
about downloading ICC profiles to the Fiery X3e, see “Downloading profiles” on page 4-5.
• The Match Copy setting bypasses Fiery X3e calibration to simulate the color of a copy produced by the copier/printer. Use this setting when you print images scanned with the Fiery Scan plug-in set to Match Copy (copier only).
CMYK Simulation Method
The CMYK Simulation Method setting specifies the quality of simulation to perform.
• Quick applies one-dimensional transfer curves that adjust output density only.
• Full provides a more complete and accurate simulation by applying colorimetric transformations that adjust hue as well as output density. The Full Simulation option also maintains the integrity of the black channel by adjusting it independently. This is especially important for images separated using an optimized black generation (UCR/GCR) setting, either from a scan or from within an application such as Photoshop.

1-9 Managing color on the Fiery X3e
Output Profile
The output profile is applied to all data in the print job, so make sure the selected profile is right for your job. The default output profile consists of both a profile for your copier/printer, describing its color characteristics, and a calibration target that describes the expected behavior of the copier/printer.
In certain cases, you may want to customize the default output profile using the
ColorWise Pro Tools Color Editor to achieve particular color effects (see page 4-12). If
so, the new customized output profile is applied to all data in the print job. Changing only the output profile does not affect its associated calibration target (since the target is based on a copier/printer model). If you want, you can edit D-Max values of the
calibration target separately (see page 4-7).
You can also use the ColorWise Pro Tools Profile Manager to download your own
output profile to the Fiery X3e (see page 4-5). Downloaded output profiles are at first
associated with the calibration target that is tied to the default output profile. As mentioned above, you can edit calibration target D-Max values separately.
Pure Black Text/Graphics
The Pure Black Text/Graphics option affects the printout for black text and vector graphics on a page. Under most circumstances it is preferable to leave this option set to
On. When Pure Black Text/Graphics is on, black colors generated by applications are printed using 100 percent black-only toner (for example, RGB = 0, 0, 0; CMYK = 0%,
0%, 0%, 100%; or K = 100%). This means the black text and line art will not exhibit halftone artifacts and will not be misregistered, since there is only one toner used. In addition, this setting eliminates blasting . This option is automatically set to On when the Black Overprint option is set to On.
For some jobs, it is preferable to clear this option, for example, if the page includes gradient fills that use black. The following table describes the behavior of the Pure
Black Text/Graphics option with black data defined in different color spaces.

N OTE : PostScript applications, such as QuarkXPress, may convert elements defined as
RGB = 0, 0, 0 to four-color CMYK black before sending the job to the Fiery X3e.
These elements are not affected by the Pure Black Text/Graphics option. For details, see the application notes. Also, black text and line art defined as RGB = 0, 0, 0 in office applications (such as Microsoft Word) are converted to single-color black (CMYK =
0%, 0%, 0%, 100%) by the Microsoft PostScript Level 2 driver for Windows NT 4.0.
To print this single-color black at the maximum toner density of the copier/printer, set the Pure Black Text/Graphics option to On.

1-11 Managing color on the Fiery X3e
Black Overprint
The Black Overprint option lets you specify whether or not black text, defined as
RGB = 0, 0, 0, or as CMYK = 0%, 0%, 0%, 100%, overprints colored backgrounds.
• On —Black text overprints colored backgrounds, eliminating white gaps and reducing halo effects or misregistration of colors. Setting Black Overprint to On automatically activates the Pure Black Text/Graphics option.
• Off —Black text knocks out colored backgrounds.
N OTE : PostScript applications may perform their own black overprint conversions before sending the print job to the Fiery X3e.
One example of how you might use this setting is with a page that contains some black text on a light blue background. The background blue color is CMYK = 40%, 30%,
0%, 0% and the black text is CMYK = 0%, 0%, 0%, 100%.
• With Black Overprint On, the final text portions of the page are overprinted, or combined with the underlying colors. This results in CMYK = 40%, 30%, 0%,
100% for the color used for the text. There is no transition in the cyan and magenta toners, and the quality of the output is improved, since it will not show artifacts near the edges of the text. The option also works with text defined in the RGB color space, that is RGB = 0, 0, 0.
• With Black Overprint Off, the border of the text is on an edge that has cyan and magenta toners on one side (outside the text) and black toner on the other side
(inside the text). On many devices, this transition causes visible artifacts because of the practical limitations of the copier/printer.

1-12 Fiery X3e Color Management
Spot Color Matching
The Spot Color Matching option provides automatic matching of PANTONE colors with their best CMYK equivalents.
• On —The Fiery X3e uses its built-in table to generate the closest CMYK matches of
PANTONE colors your copier/printer can produce. (New tables are generated when you add new output profiles.)
• Off —The Fiery X3e uses the CMYK equivalents defined by your application to print PANTONE colors.
For jobs that include PANTONE spot colors, set Spot Color Matching to On unless you are printing press simulations. In that case, set Spot Color Matching to Off and
choose the appropriate CMYK Simulation setting (see page 1-8).
N OTE : You can use the Spot Color Matching option only when printing composites, not when printing separations.
Spot Color Matching and the PANTONE Coated Color Reference
The PANTONE Coated Color Reference (described on page 5-7) prints differently,
depending on the Spot Color Matching setting.
• On —The Fiery X3e uses its built-in table to generate the best matches of the
PANTONE colors that your copier/printer can produce. The PANTONE number is printed below each swatch.
• Off —The Fiery X3e prints swatches using the CMYK values recommended by
Pantone (and used by applications that provide PANTONE color libraries). The
CMYK values used to generate the color, as well as the PANTONE number of the color, are printed below each swatch. These CMYK values are printed through the selected CMYK Simulation and Output Profile settings.

1-13 Printer Drivers and Print Options
Printer Drivers and Print Options
This section describes the role of the printer driver and explains how to use Windows and Mac OS printer drivers for Fiery X3e printing.
N OTE : The term “PostScript” by itself is used to refer to Adobe PostScript Level 2 or later.
What a printer driver does
To take full advantage of the features of the Fiery X3e, your print jobs must be sent as
PostScript data. Since most applications cannot generate PostScript data directly, it is the function of a printer driver to interpret instructions from the application and convert them to PostScript data.
A PostScript printer driver also allows you to select print options specific to your copier/printer. To do this, the printer driver must be matched with a PostScript printer description file ( PPD ) for your Fiery X3e. The PPD contains information about the particular features supported by the Fiery X3e and the copier/printer. The
PPD can be thought of as the lines of PostScript code in the file that are devicespecific. When you print a job, the printer driver lets you choose among features by displaying print options.
A few PostScript applications can send PostScript data directly to the copier/printer and present print options within the application interface. Even these applications, however, require that you use a PostScript printer driver.
Your Fiery X3e user software includes Adobe PostScript printer drivers for
Windows 95/98/Me, Windows NT 4.0, and Mac OS and the Microsoft PostScript printer driver for Windows 2000. These are the recommended printer drivers for printing to the Fiery X3e. (For information on installing printer drivers, see Getting
Started.
)
We recommend that you set the print options initially in Fiery X3e Setup (see the
Configuration Guide ). This provides you with a default configuration that is appropriate for most Fiery X3e print jobs.

For Window 95/98/Me, the Fiery X3e driver interface enables you to save combinations of settings that you can later access. Additionally, you can choose different settings for individual jobs from the applications you use.
The printer driver writes a PostScript file containing the instructions generated by your application and the Fiery X3e print options you selected. The printer driver sends the
PostScript file to the Fiery X3e. The Fiery X3e then performs PostScript processing and color conversions and sends raster color data to the print device.
N OTE : The following illustrations and instructions do not apply to all applications.
Many applications, such as PageMaker, Photoshop, Illustrator, QuarkXPress, and

Each pane presents a particular set of print options.
The AdobePS driver includes the following Color Matching options.
• Color/Grayscale —When this setting is used to print to the Fiery X3e, ColorWise provides all color conversions on the Fiery X3e. Typically, you should use this option when printing to the Fiery X3e.
• PostScript Color Matching —Can be used with PostScript devices such as the
Fiery X3e. It provides for color conversion using a color rendering dictionary (CRD) that is downloaded with the print job. This method requires that the file is saved as an EPS with PostScript Color Management checked.

1-19 Printer Drivers and Print Options
N OTE : If you use the PostScript Color Matching option, the driver may, depending on the application you are using, attach a CMYK source definition to the CMYK data in your document. In such a case, the CMYK data in your document is reseparated using a Fiery X3e CRD. The destination color space for the CRD is determined by the RGB
Separation print option. By setting RGB Separation to Simulation, CMYK data is printed according to all specified CMYK Simulation Profile and CMYK Simulation
Method settings. By setting RGB Separation to Output, CMYK data is converted to the selected output profile’s CMYK color space.
• ColorSync Color Matching —Provides for color conversion on the host computer . This option can be used with PostScript devices such as the Fiery X3e, but it is intended for use with PostScript Level 1 devices. If you use this option, be sure to specify the
Fiery X3e’s ICC profile as the Printer Profile. ColorSync Color Matching is not a suggested color matching method because it does not work in conjunction with all applications and requires that you disable features of ColorWise on the Fiery X3e.

2-1 Workflow concepts
This chapter discusses color management workflows used in short-run color printing as well as color proofing on the Fiery X3e. It also gives examples of color management in specific desktop applications and the interaction between those applications and
ColorWise color management.
Workflow concepts
The term “ workflow ” is used to describe the path a job follows from its creation in a desktop application to final printed output. It is helpful to think of the following categories when describing workflows:
• Short-run printing versus color proofing for eventual output on an offset press
• RGB, CMYK, and PANTONE color systems
• Desktop color management within an application versus color management on the
Fiery X3e, along with the notion that different versions of desktop applications handle color management differently. So it is important to pay close attention to the version of a particular application when considering the workflows in this chapter.
Short-run printing versus color proofing
Short-run color printing refers to those jobs for which the Fiery X3e is the final print device. Printing jobs to the Fiery X3e in preparation for printing on an offset press is referred to as color proofing. Both types of Fiery X3e print jobs use RGB, CMYK, and
PANTONE colors.
• For short-run jobs, bright, saturated colors are often desirable. These are achieved by using the full range of colors available, referred to as the full gamut of copier/printer, or more simply copier/printer CMYK. For short-run printing examples, see
“Advanced Workflows” on page 2-8.
• Offset jobs proofed on the Fiery X3e require the printed colors to match those from another set of CMYK printing conditions. Colors that are specified for an offset press require CMYK simulation that is optimized for proofing on the copier/printer.
For color proofing examples that simulate the gamut of another digital printer or
press standard, see “Advanced Workflows” on page 2-8.
2
2-2 Simple and Advanced Workflows
RGB, CMYK, and PANTONE colors
Colors can be defined in several different color models, the most common being RGB,
CMYK, and the PANTONE color matching system. Each model requires a different color conversion at the Fiery X3e. These different color conversion workflows are as follows:
• RGB source profiles and color rendering dictionaries (CRDs) are used to map RGB colors through a device-independent color space to a destination space, either the full copier/printer gamut in a short-run printing workflow or CMYK simulation in a color proofing workflow.
• CMYK colors are device-dependent. In a proofing scenario, colors specified in prepress applications are adjusted so the gamut of the Fiery X3e copier/printer can simulate that of the press. In a short-run printing workflow, specifying CMYK colors according to the calibrated copier/printer output eliminates the need for simulation during printing.
• PANTONE spot colors are special inks manufactured to run on an offset printing press. Spot colors can be simulated using CMYK copier/printer toners or process color inks. Two basic workflows exist for printing PANTONE colors to the
Fiery X3e:
Spot Color Matching On instructs the Fiery X3e to match the output of the copier/ printer to the PANTONE spot color.
Spot Color Matching Off instructs the Fiery X3e to match the copier/printer output to a Pantone-specified process simulation. This CMYK combination is then printed with the CMYK Simulation setting you choose, such as SWOP or Custom, and
CMYK Simulation Method set to Full.
2
2-3 Workflow concepts
Desktop versus Fiery X3e color management
A desktop color management system uses ICC profiles to convert colors from one
device gamut to the next (see Appendix B). The color data is converted when it is
passed from one application to another or when the job is sent to the copier/printer, so the processing occurs on your computer as opposed to the Fiery X3e.
One advantage of using ColorWise color management over desktop color management is that your computer is spared the added processing chores; delaying color conversions until the color data reaches the Fiery X3e frees your computer so you can continue working, and color conversions on the Fiery X3e are in most cases much faster than similar conversions on a host computer.
Managing most or all of your color on the Fiery X3e can also eliminate the potential for undesirable color management-related conflicts, such as iterative color conversions and inconsistent color. The Fiery X3e applies global corrections to specific groups of
RGB, CMYK, and PANTONE colors to avoid such conflicts.
Finally, by sending RGB files instead of larger CMYK files from applications to the
Fiery X3e, network traffic is minimized and jobs generally print faster.
ColorWise uses ICC profiles to convert colors to the copier/printer gamut or simulate other devices such as an offset printing press. ColorWise manages color conversions for all users printing to the Fiery X3e from Windows and Mac OS computers. It lets users follow a simple workflow with minimal intervention using robust default settings, while giving advanced users the control and precision they need.
The Fiery X3e can intelligently manage the printed appearance of RGB, CMYK, and
PANTONE colors. You can let the Fiery X3e manage color for most short-run color printing jobs without adjusting any settings.
2
2-4 Simple and Advanced Workflows
Simple workflows
Every time you print a document containing colors that were not chosen for your specific copier/printer, those colors must be converted, which requires color management. Colors can be defined or modified at any stage in the workflow. Since
ColorWise is compatible with most other color management systems, you can use the workflow most familiar to you.
This section provides examples of color workflows that should meet the needs of most
Fiery X3e users. For information on specific desktop applications, see Chapters 6
Select your colors wisely
For the colors you see on your monitor to match those on your printed output, they must go through color management, including precise calibration of your monitor and copier/printer. If you are not equipped or inclined to maintain accurate monitor color management, you may opt for an easier approach. Determine which is more important for you—printed colors or monitor displayed colors.
If displayed colors are more important, trust your eyes and your monitor. Visually select colors on your monitor, but be aware that colors will be optimized only for your monitor. When the document is opened on other monitors, the colors may look different. And even though printed colors may not match those displayed on your monitor, they will still print on the Fiery X3e with good results.
If printed colors are your priority, choose colors from printed samples. By using these sample colors, your printed output will remain consistent regardless of how the colors appear on different monitors. Print the palette of available colors from business applications and then select colors from the printed samples. The Fiery X3e comes
with color reference files on the user software CD (see page 5-2). You can also print the
color charts from the Control Panel and select colors by number or name from the printed samples. Advanced applications let you define colors in the easier-to-control
PANTONE and CMYK color spaces. For more advice on color selection, see
2
2-5 Simple workflows
No matter which workflow most closely matches your own, you should calibrate your
copier/printer regularly (see Chapter 3).
Select a short workflow
Every time colors are converted, performance and color accuracy are affected.
Therefore, a workflow with fewer steps minimizes the risk of error.
Workflow 1 using ColorWise calibration—minimal workflow
A minimal color workflow requires that you calibrate the copier/printer. Select from printed colors, as described above, and set the CMYK Simulation option to None, since simulation is not needed when colors are already defined using CMYK values optimized for your calibrated copier/printer.
N OTE : CMYK Simulation set to None is also useful when you want to prepare an output profile of your calibrated copier/printer or when you use less efficient color management from the desktop (such as ColorSync or ICM).
In this workflow, colors are modified only at the calibration stage. This is indicated by the black box in the following diagram.

While this workflow lends some control over the color quality produced by the copier/ printer, you should consider additional ColorWise color management, as described in the following section.

2-6 Simple and Advanced Workflows
Workflow 2 using ColorWise color management—standard workflow
Fiery X3e servers are highly optimized for the specific copier/printer they drive, and
ColorWise addresses many issues unique to your copier/printer, including screens, individual toner response, interactions among toners, natural smoothness of blends, and the capability to render PANTONE and custom colors. The Fiery X3e distinguishes text and graphic from image elements, so the black channel information is preserved while parameters used for CMYK color separations are maintained.
Conventional color management systems typically address only color conversions, and they occupy your computer’s processor. When you use ColorWise, jobs leave your computer faster to be processed more quickly on the Fiery X3e.
The recommended standard color workflow (indicated by the black boxes in the following diagram) uses ColorWise calibration and color management.
Workflow 2—Colors you define in an application Colors in output from the copier/printer

The Fiery X3e comes into play near the end of the color workflow. To ensure that the colors you have selected reach the Fiery X3e and ColorWise in a usable form, you should bypass any color management from applications and printer drivers. Keep in mind, however, that color management from applications and printer drivers is fully
supported by ColorWise (see “Advanced workflows” on page 2-8).
You must print with the CMYK Simulation print option set to match the CMYK color space in your application when you selected the colors. Any CMYK Simulation setting (except Match Copy) applies calibration, so the response of the copier/printer will appear to be stable.
The recommended values for CMYK Simulation are SWOP in America, Euroscale in
Europe, and DIC in Japan—choices that respect the color standard for each region. If colors have been selected specifically for your calibrated copier/printer, set CMYK
Simulation to None.

2-7 Simple workflows
For the list and descriptions of ColorWise print options affecting CMYK, RGB,
PANTONE, and other colors, see the table on page 1-3.
Workflow 3 bypassing ColorWise— not recommended
Bypassing ColorWise color management, while an option, is not a recommended workflow. When you bypass ColorWise, you must choose colors using only CMYK formulas designed specifically for your copier/printer, and you must print with the
CMYK Simulation option set to Match Copy. The Fiery X3e still prints pages using your PostScript files, and drives the copier/printer and its accessories, but it does not perform CMYK color transformation, nor does it consider the calibration of the copier/printer. Calibration is needed in order to get consistent output, since the color response from your copier/printer varies significantly depending on wear, heat, humidity, and service.
The following diagram indicates that no modifications are made to colors in this workflow.

Turn off color management in your application
Generally, when printing to the Fiery X3e, it is best to disable color management in the application to ensure that the Fiery X3e receives color data properly and prints it accurately.
Save your files using color-safe settings
You can take several additional steps to ensure color accuracy.
• When saving EPS files, do not include PostScript Color Management information.
This minimizes the risk conflicting data and multiple color conversions. PostScript
Color Management causes your CMYK and RGB colors to be interpreted by the
Fiery X3e as though they were supplied in the Lab color space and, as a result, to be processed by CRDs rather than your simulation settings.
2
2-8 Simple and Advanced Workflows
• Include ICC color information in files. ColorWise will not conflict with this information, and such data can be useful to identify the specific color space used by your files.
• Do not include halftone and transfer functions.
• Turn off color management in the printer driver.
On Windows machines, if the printer driver offers Image Color Matching options, select Printer Image Color Matching.
On Mac OS computers, set the printer driver to include no color management
commands at print time (see page 1-18).
Advanced workflows
The following sections present advanced color management workflow examples for three short-run printing and three color proofing situations. Each workflow example consists of a brief description, steps for creating and manipulating the files, a list of the
ColorWise settings used in the example, and a table that summarizes the workflow.
N OTE : These examples use specific software packages to represent image editing, illustration, page layout, and business/office applications; they are Adobe Photoshop,
Adobe Illustrator, QuarkXPress, and Microsoft PowerPoint, respectively.
Short-run printing examples
The following examples illustrate short-run printing on the Fiery X3e.
Photoshop RGB workflow
This short-run workflow of printing an RGB image from Photoshop is one of the simplest Fiery X3e color workflows. In it, RGB data is sent from the application, through the printer driver, to the Fiery X3e. The RGB-to-CMYK conversion takes place on the Fiery X3e using a CRD rather than in the application. Use the settings in this workflow for printing photographs and artwork.

3-1 Introduction
Chapter 3:
Color Calibration
Calibrating the Fiery X3e ensures consistent, reliable color output. You can calibrate the Fiery X3e with ColorWise Pro Tools using an X-Rite DTP32 automatic scanning densitometer (available as an option that is purchased separately). By connecting the densitometer to the serial port on your computer, you can quickly measure color patches and download measurements to the Fiery X3e. You can also obtain measurements from the copier’s built-in scanner (copier only) and calibrate using
AutoCal2 ™ , which does not require the use of a densitometer and can be run from
ColorWise Pro Tools or the Control Panel. VisualCal ™ is intended for use with the printer model only and is run from the Control Panel on the Fiery X3e.
This chapter explains how calibration works and provides instructions for all calibration procedures. Calibrating with ColorWise Pro Tools is described on
page 3-9; calibrating from the Fiery X3e Control Panel with AutoCal2 is described on
page 3-16. VisualCal is described on page 3-18.
For information on advanced calibration and simulation features available with
ColorWise Pro Tools, such as editing profiles and creating custom profiles, see
Chapter 4. A format for inputting color measurements from other densitometers is
The procedures described in Chapters 3 and 4 are fundamentally the same for
Windows 95/98/Me, Windows NT 4.0, Windows 2000, and Mac OS computers, including those running Command WorkStation software. The main differences are the interface cable and the port used to connect to the densitometer.
N OTE : The term computer is used to refer to any computer running ColorWise
Pro Tools.
Introduction
Calibration generates curves that adjust for the difference between the actual toner densities (measurements) and the response expected by the output profile.
• Measurements represent the actual color behavior of the copier/printer.
• Calibration sets are sets of measurements.
3
3-2 Color Calibration
• A calibration target that describes the expected behavior of the copier/printer is contained in each output profile.
Once you have calibrated the Fiery X3e with ColorWise Pro Tools, with AutoCal2 from the Fiery X3e Control Panel, or with VisualCal, a calibration set is stored on the
Fiery X3e. This calibration set will be used when it is associated with an output profile.
Every output profile has an associated calibration set. If you have not specified one, the calibration set associated with the default output profile is used.
N OTE : Changing calibration has the potential to affect all jobs for all users, so you may want to limit the number of people authorized to perform calibration. You can set an Administrator password from the Fiery X3e Control Panel or in Setup from
Command WorkStation to control access to calibration.
Understanding calibration
Although most users’ needs are met by the default calibration set, the Fiery X3e allows you to choose a calibration set to customize calibration for specialized jobs.
Calibration allows you to:
• Maximize the color reproduction capabilities of the Fiery X3e.
• Ensure consistent color quality over time.
• Produce consistent output across Fiery X3e servers that are connected to the same print engine.
• Achieve better color matches when reproducing spot colors such as PANTONE colors or other named color systems.
• Optimize the Fiery X3e for using ColorWise rendering styles (CRDs) and CMYK simulations, and for using ICC profiles.
3
3-3 Understanding calibration
How calibration works
Success in obtaining satisfactory print quality from a color server such as a Fiery X3e connected to a copier/printer depends on many factors. Among the most important are establishing and maintaining optimal toner densities. Density is a measure of the light absorbed by a surface. By carefully regulating toner densities, you can obtain consistent printed color.
Even with a calibrated system, toner density is affected by service settings, humidity, and temperature; it also tends to drift over time. Regular measurement detects day-today variations in densities, and calibration corrects for them.
Calibration works by creating calibration curves on the Fiery X3e that compensate for the difference between actual (measured) and desired (target) density values.
Calibration curves are the graphic equivalent of transfer functions, which are mathematical descriptions of changes that will be made to the data you start with.
Transfer functions are often graphed as input or output curves.
The Fiery X3e generates calibration curves after comparing measured values to the final target values for each of the four toner colors. The target values are based on the output profile specified.
Measurements
Measurement files contain numerical values that correspond to the toner density produced by the copier/printer when it prints solid cyan, magenta, yellow, and black, and graduated tints of those colors.
To create a measurement file, first print a page of color patches from ColorWise
Pro Tools. Then you measure the patches using an X-Rite DTP32 densitometer connected to a computer on the network or the copier’s scanner. The new measurements are automatically downloaded to the Fiery X3e.
3
3-4 Color Calibration
Output profiles and calibration sets
Output profiles and calibration sets define desired calibration results. One or more output profiles and one or more calibration sets are provided with the Fiery X3e.
When you calibrate the Fiery X3e, you can select the calibration set that corresponds to the typical printing jobs at your site. This same calibration set can be associated with
one or more output profiles. (For more information on output profiles, see page 1-9.)
Scheduling calibration
In general, you should calibrate the Fiery X3e at least once a day, depending on the volume of print jobs. If it is very important to maintain consistent color, or if the copier/printer is subject to wide fluctuations in temperature or humidity, calibrate every few hours. To get the best performance, calibrate whenever there is a noticeable change in print quality.
If you need to split a print job into two or more batches to be printed at different times, it is especially important to calibrate before printing each batch. You should also calibrate the Fiery X3e after copier/printer maintenance. However, because the copier/printer may be less stable immediately after maintenance, wait until you have printed approximately 50 pages before you calibrate.
N OTE : Since printed output from the copier/printer is very sensitive to changes in temperature and humidity, the copier/printer should not be installed near a window or in direct sunlight, near a heater or air conditioner. Paper is sensitive to climate changes as well. It should be stored in a cool, dry, stable environment, and reams should remain sealed until they are needed.
Print color reference pages, such as the Color Charts (from the Control Panel or from
Command WorkStation) and the color reference pages included with the user software
(see Getting Started ). All of these pages include fully saturated color patches and pale tints of cyan, magenta, yellow, and black. Images with skin tones offer a very good basis for comparison. You can save and compare pages you printed at different times. If there is a noticeable change in appearance, you should calibrate the Fiery X3e.
3
3-5 Understanding calibration
When you examine the Test Page, keep in mind that all color patches should be visible, even though they may be very faint in the five percent and two percent range, and each color’s patch set should show uniform gradation from patch to patch as the color lightens from 100 percent to zero percent.
If the solid density patches (100% cyan, magenta, yellow, or black) look less saturated with time, show the pages to your copier/printer service technician to find out whether adjusting the copier/printer can improve output.
Checking calibration status
You can check whether the Fiery X3e is calibrated, which calibration set and output profile were used, and when the copier/printer was last calibrated:
• Print a Configuration page or Test Page from the Control Panel or Command
WorkStation.
• When you select a calibration set in Calibrator, the last calibration and the user who performed it are displayed.
3
3-6 Color Calibration
Using a densitometer
ColorWise Pro Tools are designed to work with the X-Rite DTP32 reflection densitometer, which feeds color measurements to the Fiery X3e automatically.
N OTE : Measurements from other densitometers can be input using a simple ASCII file
Setting up the densitometer
Before you calibrate the Fiery X3e using the X-Rite DTP32, you need to connect, configure, and calibrate the densitometer to prepare for measuring the printed patches
(see “Calibrating the densitometer” on page 3-8). For additional information about
setting up and using the DTP32, see the separate documentation included with it.

Calibrating from the Control Panel using VisualCal
VisualCal is a calibration method that allows you to calibrate your printer to a color output standard defined by the manufacturer. The calibration calculations performed by the controller software are based on a series of values entered on the Control Panel.
The values used in the calculations are determined by evaluating toner densities and color combinations produced on two specially designed calibration pages printed from the control panel.
Limits and 30% Match
The first VisualCal page, “Limits and 30% Match,” provides the basis for calculating the most acceptable luminosity (brightness) of the toners. This page consists of rows of
CMYK dots in a graduated range of toner densities.
The variables needed to recalculate the density of the colored toners are determined by identifying the leftmost dots that can be fully distinguished against their fields in each row, and sequentially entering their corresponding numeric values on the control panel. The variable needed to recalculate the luminosity of the toners is determined in a slightly different way—you identify the black dot that best matches a 30% dot gain field. When all values have been entered, the printer’s toner density and luminosity settings are recalculated.
3
3-19 Calibrating from the Control Panel using VisualCal
Gray Balance
The second VisualCal page, “Gray Balance,” provides the basis for calculating a
“neutral gray balance”—that is, a CMY gray that as closely as possible matches a pure
K (blacK) gray produced by the printer’s engine. This page consists of rows of CMY gray patches on a field of gray produced solely from black.The variables needed to calculate the printer’s most neutral gray balance are determined by identifying the
CMY patch that best matches this field, and entering its row and column location on the control panel. When the values have been entered, the printer’s gray balance is recalculated.

4-1 Profile Manager
ColorWise Pro Tools are color management applications that give you flexible control of color printing. The four tools are:
• Calibrator (see Chapter 3)
• Color Editor
• Profile Manager
• Color Setup
ColorWise Pro Tools for Windows and Mac OS computers are fundamentally the same; differences are noted in this chapter. The windows and dialog boxes illustrated are the Windows versions. For information on installing and configuring a connection to ColorWise Pro Tools, see Getting Started .
N OTE : If the connection to the Fiery X3e from Command WorkStation that also allows for access to ColorWise Pro Tools is not established, you can start
ColorWise Pro Tools independently of Command WorkStation.
Profile Manager
Profile Manager allows you to manage and edit ICC profiles. In the case of the
Fiery X3e, these profiles are divided into RGB Source, Simulation, and Output profiles.
• RGB Source contains all monitor profiles resident on the Fiery X3e. RGB Source profiles are used to define the source color space for RGB colors processed by the
Fiery X3e.
4
4-2 ColorWise Pro Tools
N OTE : If you use Photoshop 5.x, you can upload the profile for your selected working space to the Fiery X3e and choose that as your RGB Source profile.
• Simulation contains printer profiles used to simulate another device on the
Fiery X3e.
• Output contains copier/printer profiles that describe the copier/printer. For more
information on output profiles, see page 1-9.
N OTE : Changing the Fiery X3e default profiles affects all jobs for all users. You may want to limit the number of people authorized to use ColorWise Pro Tools by setting an Administrator password.
Several profiles are provided with the Fiery X3e, and you can create additional ones as needed by modifying the existing ones. You can also download profiles from any workstation to the Fiery X3e. The profiles provided are:
RGB Source:
• sRGB (PC) —source color space for a generic Windows computer monitor
• Apple Standard —standard source color space for Mac OS computer monitors with older versions of ColorSync
• EFIRGB —preset default setting for a Fiery X3e
Simulation:
• SWOP-Coated —United States press standard
• Euroscale —European press standard
• DIC —Japanese press standard
Output:
• Fiery 20C-M v1F —profile that describes the copier
• Fiery 20CP-M v1F —profile that describes the printer

4-3 Profile Manager
Setting the default profiles
The default profiles are applied to all print jobs sent to the Fiery X3e, unless you override them using print options. Therefore, the defaults should be the most commonly used profiles.
T O SPECIFY A DEFAULT PROFILE
1.
Start ColorWise Pro Tools and click Profile Manager.
On the left side of the screen are the ICC profiles in the default directory of your computer. The right side displays the three types of profiles on the Fiery X3e.
The Lock icon ( ) to the left of a profile name indicates that the profile cannot be deleted and can be edited only if it is saved under a new name. Only Simulation and
Output profiles can be edited.
A small icon to the left of a profile name indicates the default profile for each category
(RGB Source, Simulation, and Output). If you designate a different profile as the default, the icon appears next to your designated profile. The icon indicating the default RGB Source and Output profiles looks like a target ( ). The icon indicating the default Simulation profile changes in appearance depending on whether the default
RGB Separation setting is set to Simulation ( ) or Output ( ).

3.
When the profile you want to download appears in the list in the main Profile Manager window, select it.
If the profile is compatible with the Fiery X3e, a green arrow indicates that the profile is available for download. Only output device profiles are downloadable to Simulation and Output. Only input device profiles are downloadable to RGB Source.
N OTE : On Windows computers, the profiles must have an extension of .icc or .icm to be listed. On Mac OS computers, the profiles must have a file type of profile.
All ICC profiles in the selected directory on your computer are displayed in the list in the main Profile Manager window. However, because a profile is listed does not necessarily mean it can be downloaded to the Fiery X3e.
Simulation profiles should be only profiles of devices for which you want the Fiery X3e to match in terms of color output characteristics. Output profiles should be only profiles of the device to which your Fiery X3e is connected. Although CMYK printer profiles can be downloaded as Simulation or Output, consider how they will be used.
If you want the Fiery X3e prints to look like another printer, download that profile as a
Simulation. If you have a custom profile of the copier/printer, download that profile as an Output profile.
4.
Click the arrow to download the profile and click OK when the download is complete.
The new profile now appears on the list of profiles on the right side of the Profile
Manager main window.
This profile must be associated with one of the predefined names (Source-1 through 10 for RGB Source, Simulation-1 through 10 for Simulation, or Output-1 through 10 for
Output) or set as the default before it can be used. “Defining profiles” on page 4-8.
N OTE : When an output profile is downloaded, it inherits the calibration target of the current default output profile.

4-12 ColorWise Pro Tools
Color Editor
Color Editor is used to customize simulation and output profiles. You can access Color
Editor directly, by clicking its icon in the ColorWise Pro Tools main window, or indirectly through the Profile Manager.
Editing Profiles
Color Editor allows you to create custom profiles by editing existing simulation or output profiles and saving the changes as a new profile. With Color Editor, you can fine-tune a profile on your Fiery X3e to meet your exact specifications.
N OTE : You cannot edit source profiles; only simulation and output profiles can be customized.
Color Editor has two Edit Modes for editing output profiles.
• Custom —Use Custom to edit output profiles and save customized versions of them.
• % Density —Use % Density to view the calibration target, which is one component of the output profile. You cannot make changes to the calibration target in this
window, but you can import a new target (see page 3-2).
Color Editor also has three Edit Modes for editing simulations.
• Master —Use Master mode to create a custom master simulation that affects all print jobs to which it is applied, unless a linked simulation exists for the selected combination of simulation profile, simulation method, and output profile.
• Quick or Full —Use Quick or Full mode to create custom linked simulations. Linked simulations affect the print job only if the corresponding simulation profile, simulation method, and output profile are selected. If you choose an output profile and simulation method for which you have created a custom linked simulation, that simulation is applied automatically to the job. If you choose a simulation method or output profile for which there is no custom linked simulation, then the master simulation is automatically applied.
4
4-13 Color Editor
Quick applies one-dimensional transfer curves that adjust output density only, while
Full provides a more complete and accurate simulation by applying colorimetric
transformations that adjust hue as well as output density (see page 1-8).

Select the colors you want to edit by turning colors off and on.
The Eye icon to the left of each color indicates whether that color is visible on the graph and will be affected by changes to the curves, brightness, and dot gain controls.
You can view and edit all four colors (cyan, magenta, yellow, and black) at once or any combination thereof. Working with only one or two colors at a time helps you finetune your adjustments. To turn off a color, click its Eye icon. In the following example, cyan and magenta are visible and can be edited.
6.
Click Dot Gain to adjust the dot gain value for simulating press output.
You can choose either the North American or European standard, and use the sliders to select the desired Dot Gain:
• The range of values for North American at 50% input are from 0% to 50% gain on output.
• The range of values for European at 40% input are from 0% to 59% gain on output; the range of values for European at 80% input are from 0% to 20% gain on output.
A curve with this shape makes a color appear lighter by reducing density in the midtones.
4
4-16 ColorWise Pro Tools
If you use Dot Gain values, apply the settings first, so that the curves are deflected from their straight-line positions. Then make edits to the new curves. When you adjust Dot
Gain values, all existing points on the curve are removed. A warning dialog box allows you to cancel Dot Gain settings before they are applied.
7.
Use the plus and minus buttons to adjust brightness.
Changes to the brightness are reflected in the curve(s).
8.
To adjust the curves directly, click and drag points on the curve or enter numbers into the input and output boxes.
The graph maps the input percentage to the output percentage. (These percentages refer to the size of the CMYK halftone dots.) The curve you selected appears, and points along the curve are marked so you can adjust them.
A curve with this shape makes a color appear darker by adding density in the midtones.
A curve with this shape increases contrast.
N OTE : You should adjust points in this way only after you have entered the Dot Gain and Brightness values.

For an output profile, you can set maximum densities of the C, M, Y, and K channels.
You can enter the maximum densities, called D-Max values, of individual colors for profiles that support density settings. D-Max settings are not available when editing
Simulation profiles in Master mode.
10.
When you are finished, click Save and enter a name for the new profile.
The new custom profile is saved to the Fiery X3e with the new name. If you edit one of the press standard targets (for example, SWOP-Coated, DIC, or Euroscale), you may want to include the original name as part of the new target name, for example, DICnew, to help you remember the source of the new target.
N OTE : Preset default profiles are locked and must be saved with a new name.
Custom profiles must be linked to one of the 10 predefined custom profile names
(Simulation-1 through 10 for simulation or Output-1 through 10 for output) in order to be accessible from the printer driver. You can create as many custom profiles as you want, but a maximum of 10 are available from the printer driver at any one time.
For information on linking custom profiles to the predefined custom profile names,
see “Defining profiles” on page 4-8.

5-1 Working with color
Chapter 5:
Working with
Color in
Applications
This chapter provides guidelines for defining colors in your documents to produce the results you want. The following topics are covered:
• Factors affecting how you work with color
• Choosing colors in applications that rely on GDI or QuickDraw to communicate data to the printer driver, such as presentation applications and word processing programs
• Choosing colors in applications that have the ability to write their own PostScript, such as some page-layout programs, illustration programs, and pixel-editing applications
Working with color
The two main factors that influence how you work with color in the creation of documents are the applications you use and the final print device. Applications vary in the methods they provide for choosing colors and in the way they transmit color data to the print device.
• Office applications such as presentation software, spreadsheets, and word processing programs use the RGB color model. They typically transmit only RGB data to the print device.
• Illustration applications use both the RGB and CMYK color models, but typically transmit only CMYK data to the print device.
• Pixel-editing applications use both the RGB and CMYK color models. They also transmit both RGB and CMYK data to the print device.
5
5-2 Working with Color in Applications
The type of printing you plan for the document—short-run color printing on the
Fiery X3e versus color printing for eventual printing on an offset press—determines the way you define colors, as well as the print option settings you choose.
• For short-run color printing on the Fiery X3e, use any type of application and define colors in either RGB or CMYK. If your application supports it, you can also choose colors from the PANTONE color library. Placed images may be limited to the RGB color space. Choose the appropriate settings for print options affecting color output
• For color proofing, use an application that writes its own PostScript and define colors in RGB or CMYK, or choose colors from the application’s PANTONE color library. Placed images can also be defined in RGB or CMYK. Choose the
appropriate settings for print options affecting color output (see page 1-1).
N OTE : The Fiery X3e allows you to use RGB or CMYK data when printing proofs for an offset press run. However, sending data to an imagesetter most often requires
CMYK data.
Color reference pages
Fiery X3e user software includes several types of color reference pages that let you see the range of colors that can be printed on your copier/printer. For predictable color, use the color reference pages when defining the colors in your document.
• RGB Color Reference—a Microsoft Word file and a Microsoft PowerPoint file that let you view the colors available in the standard palettes of office applications and see
how those colors print on the Fiery X3e (see page 5-4).
• CMYK Color Reference—an 11-page downloadable PostScript file of CMYK color
• PANTONE Coated Color Reference—a 19-page downloadable PostScript file of color patches showing CMYK equivalents of PANTONE Coated colors. This file prints differently depending on the setting of the Spot Color Matching option (see
5
5-3 Office applications
In addition, you can print RGB, CMY, and PANTONE color charts from the
Fiery X3e Control Panel.
Office applications
The Fiery X3e must receive PostScript instructions to print an image or a document.
Many applications do not create these PostScript instructions, relying instead on the printer driver to create them. Included in this category are most word processing, spreadsheet, and presentation graphics applications. These applications use Windows
Graphics Device Interface ( GDI ) to display and print when running under Windows and Apple QuickDraw to display and print when running on Mac OS computers. We refer to these GDI and QuickDraw applications as “ office applications .”
All office applications handle color similarly, using the same RGB color model used for the color monitor. Most office applications allow you to choose colors from a palette of preselected colors; some allow you to add new colors to the palette using a color picker.
Although some applications allow you to specify color using the CMY, HSL, and HSV color models, these applications always send RGB color data to the Fiery X3e. (An exception to this is a CMYK EPS file placed in the document, which is sent as CMYK data.)
When working with color in office applications, keep in mind that:
• The range of colors that can be displayed in RGB on your monitor is much larger than the range of colors that can be printed on your copier/printer. When you print the document, out-of-gamut RGB colors are mapped to colors your copier/printer can produce.
• These applications send only RGB data to the Fiery X3e. You control the rendering style of the color conversion with your selection of a CRD.
Each CRD uses a different color rendering style, and therefore has a different way of mapping unprintable colors to the color gamut of your copier/printer. For more
information on Fiery X3e color rendering styles, see page 1-5.
RGB Color Reference

5-4 Working with Color in Applications
Choosing colors in office applications
Two RGB color reference pages, a Microsoft Word file and a Microsoft PowerPoint file, are provided with your Fiery X3e user software. Print these files using different CRDs to see how the colors appear when printed to the Fiery X3e. For best results, print the color reference page using the same print options you plan to use for your final document. Select the colors you want to use from the printed version of the RGB color reference page and then use those colors in your document.
PostScript applications
Most applications used for illustration, pixel editing, and page layout can create the
PostScript information they send to PostScript copier/printer or save in PostScript files.
Illustrator, Photoshop, PageMaker, QuarkXPress, and FreeHand are all PostScript applications.
5
5-5 PostScript applications
PostScript applications work with color in many different ways. Most allow you to choose process colors (by entering percentages for cyan, magenta, yellow, and black), as well as named colors from a custom color system such as PANTONE. When you print composites, these applications send process-color equivalents for named spot colors to the copier/printer. In some applications, you can also choose colors using the
RGB, HSB, HSL, or other color models.
Generally, PostScript applications send color information to the Fiery X3e as CMYK data. An exception to this is an RGB image placed in the document, which is sent directly to the Fiery X3e (unless you specify special color management settings in the application). In addition, some PostScript applications that allow you to define colors in RGB or other color models can also send data to the Fiery X3e in those color spaces.
Color controls in PostScript applications are typically designed for printing on an offset press, and some adjustments are required for printing to the Fiery X3e.
Displayed versions of colors you choose in these applications may not match Fiery X3e output exactly, and named colors may not print accurately on the Fiery X3e, since these colors typically require custom inks.
Choosing colors in PostScript applications
With PostScript applications, you can create colors using any of the color models supported by the application. All PostScript applications support CMYK; some also support RGB and other color models based on monitor display values. PostScript applications also allow you to choose named colors using one or more color libraries,
such as PANTONE (see page 5-7).
You should use swatch color matching to ensure predictable color printing results with the Fiery X3e or to match your Fiery X3e color output to colors produced by other print devices.
CMYK Color Reference

5-6 Working with Color in Applications
Swatch color matching
Fiery X3e user software includes several color reference pages (see page 5-2). By
choosing colors from these reference pages, you can obtain the same color from your copier/printer. For best results, calibrate the Fiery X3e before printing the reference pages.
N OTE : Swatch color matching does not match monitor colors to printed colors. For this you must use a color management system and calibrate your monitor.
Using the CMYK Color Reference
The CMYK Color Reference included with your Fiery X3e user software lets you see how various cyan, magenta, yellow, and black combinations look when printed on your copier/printer.

PANTONE Coated Color Reference
The PANTONE Coated Color Reference included with your Fiery X3e user software can help ensure predictable results with colors chosen from the PANTONE color library.
The information printed by the PANTONE Coated Color Reference depends on the
Spot Color Matching setting.
• On —Prints swatches of the closest equivalents of PANTONE colors your copier/ printer can produce. The equivalent PANTONE color name/number is printed below each swatch.
• Off —Prints swatches of the CMYK equivalents of PANTONE colors as defined by
Pantone. (These are the same CMYK values defined in applications that include
PANTONE libraries.) The CMYK values used to produce the color, as well as the
PANTONE color name/number, are printed below each swatch.
To print the PANTONE Coated Color Reference, download the file to the Fiery X3e.
(For the location of the file on the User Software CD, see Getting Started .) If the default Spot Color Matching setting on the Fiery X3e is not the setting you want to use for printing the PANTONE colors, download the file to the Hold queue. Then use
Fiery WebSpooler, Fiery Spooler, or Command WorkStation to override the Spot
Color Matching setting.

5-8 Working with Color in Applications
Default output profile
The default output profile consists of both a profile for your copier/printer, describing its color characteristics, and a calibration target that describes the expected behavior of
the copier/printer. For more information on output profiles, see page 1-9.
In certain cases, you may want to customize the default output profile to achieve
particular color effects (see page 4-12). If so, the new customized output profile is
applied to all data in the print job. You can also use ColorWise Pro Tools to download
your own output profile to the Fiery X3e (see page 4-5). Downloaded output profiles
are at first associated with the default calibration target.
CMYK simulation
If you are using the Fiery X3e to print proofs for an offset press job or simulate another print device, choose the appropriate CMYK Simulation Profile and CMYK Simulation
Method print option settings (see page 1-8).
Chapter 6:
Office
Applications

6-1 Working with office applications
This chapter provides instructions for printing color documents from GDI and
QuickDraw applications such as presentation, spreadsheet, and word processing applications. You can use these instructions with the Microsoft Office 2000, Microsoft
Office 97 and Microsoft Office 95 suite of applications.
Working with office applications
Before printing from these applications, make sure the appropriate printer driver and the Fiery X3e PPD are installed on your computer, as described in Getting Started . The
Fiery X3e ColorWise color management system provides complete color management for jobs printed from office applications.
Defining colors
Office applications use the RGB color model. For instructions on defining colors, see
“Choosing colors in office applications” on page 5-4.
The only way to use CMYK or PANTONE colors is to define them in EPS files with an illustration or page layout application, and then place these files into MS Office documents. Colors in EPS files are preserved until they reach the Fiery X3e (assuming no PostScript Color Management information was included).
MS Office applications lack finesse when displaying EPS files, so use these files only when RGB colors are not practical in your specific workflow. EPS files are also useful when using large or complex images that need to be printed at full resolution or cannot fit some MS Office configurations with limited memory.
Working with imported files
Although your application may allow you to import a variety of file formats, EPS files are recommended for all raster images you want to import; some applications have printing problems when using file formats such as TIFF and PICT.
N OTE : You may have to perform a “custom install” of your Office application if you are not able to import EPS elements.
6
6-2 Office Applications
Although there are no color management options within Office applications, color conversions do occur when you import images or page elements that were not defined in RGB. To avoid such conversions with imported files, use the EPS file format for artwork that is to be imported into Office applications.
All RGB images placed in a document are affected by RGB Source and Rendering
Style settings.
Tip for advanced users
If you place multiple RGB images, mixed non-photographic and photographic, a single CRD may not be suitable for all the images. In this case you may want the photographic images to bypass the CRD altogether. To accomplish this, save the image in CMYK mode with a pixel-editing application such as Photoshop and perform color correction. Then save it as an EPS file and import it into the document.
Selecting options when printing
There are few differences among office applications with regard to Fiery X3e printing.
The instructions in this chapter apply to all office applications. Use the instructions in
Chapter 1 to specify print options and color management settings. To specify these
options, you must use a PostScript Level 2 (or later) printer driver, such as an Adobe
PostScript Printer Driver.
Because office applications send RGB data to the Fiery X3e, your choices of
RGB Source and Rendering Style settings are important. Be sure to specify the
appropriate CRD for the color effect you want (see “Rendering styles” on page 1-5).
Output profiles
All color data in the job is affected by the output profile on the Fiery X3e. This profile may be the one designed for your copier/printer and shipped with the Fiery X3e, or it
may be a custom profile created at your site (see page 1-9). If necessary, print the Test
Page to see which profile is currently resident on the Fiery X3e.

7-1 Photoshop 5.x
This chapter covers features of Adobe Photoshop versions 4.x and 5.x for Windows and Mac OS. The illustrations show only Mac OS dialog boxes, but the information and instructions apply equally to the Windows version of Photoshop.
Photoshop 5.x
Because Photoshop 5.x uses a sophisticated color management system, there are several setup steps you should take before you begin working. These steps include:
• Calibrating your monitor
• Adjusting Photoshop color settings
• Setting ColorSync defaults (Mac OS only)
For information on monitor calibration and color setup in Photoshop (version 5.02 or later), open the Adobe Color Management Assistant (Mac OS) or Adobe Color
Management Wizard (Windows) by choosing Help>Color Management. (See your
Adobe Photoshop 5.x documentation or the Adobe Technical Guidelines for
Photoshop at www.adobe.com.)
Photoshop 5.x color settings
Photoshop 5.x has a control panel and three setup dialog boxes that control how color is managed when you open and save RGB and CMYK images. You should calibrate your monitor using the Adobe Gamma control panel and specify settings in the
Photoshop Profile Setup, RGB Setup, and CMYK Setup dialog boxes before you begin working with images in Photoshop.
N OTE : The Adobe Gamma control panel performs similar functions on both
Windows and Mac OS computers.
7
7-2 Adobe Photoshop
Adobe Gamma control panel
You can use the Adobe Gamma control panel to create and customize ICC profiles for your monitor. Photoshop properly displays images on your monitor by compensating between your chosen working space (see the following section on RGB Setup) and the description of your monitor defined by its profile. If you do not create a profile in the
Adobe Gamma control panel that corresponds to your monitor, you may encounter poor monitor-to-print matching.
N OTE : If a profile for your particular monitor is not available, use the Adobe Gamma control panel setup Assistant (Wizard on Windows) to customize an available profile that at least has the same type of phosphors as your monitor.

In the Embed Profiles area, select all options to embed the appropriate ICC profile when saving a file.
By embedding a profile during the saving process, Photoshop can link a color space
(working space) definition with that file for future use. When you open an image that already contains a profile, Photoshop can alert you as to which color space the file was saved in. Be aware that you should avoid conversions between color spaces as much as possible (each conversion results in loss of color information).
5.
In the Assumed Profiles area, choose Ask When Opening from the RGB and
CMYK menus.
When you open files that do not contain an ICC profile, you can convert the file to your current Photoshop working space setting or leave the file unconverted—the preferred choice, but make sure the current Photoshop working space setting matches the intended color space of the image.
6.
In the Profile Mismatch Handling area, choose Ask When Opening from the RGB and

7
7-4 Adobe Photoshop convert. When you open the image, immediately go to RGB or CMYK Setup to specify the working space for the image. If your working space is set to your output device, you may want to convert.
RGB Setup
Photoshop 5.x allows you to simultaneously use two RGB spaces, one for the monitor and one for the Photoshop RGB working space. The monitor RGB space setting does not affect the image data in the file; it affects only the way the image is displayed on the monitor. Even if an RGB image has been prepared with different monitor settings, it is still correctly displayed on your monitor, without changes to the original values in the file.

Tips for advanced users
Use the following information to implement alternate, more complex, color workflows with Photoshop.
Saving EPS Documents with PostScript Color Management
Selecting the PostScript Color Management option when saving either a CMYK or
RGB EPS file prompts Photoshop to embed PostScript color information—which is independent of ICC profiles—in the resulting document. This information is intended for PostScript devices like the Fiery X3e.
Printing RGB EPS Files Saved with PostScript Color Management
When you print an RGB EPS file that contains an embedded profile to the Fiery X3e, the working space information from the embedded RGB profile can be used as an
RGB source definition for Fiery X3e CRDs.
To use the source color space information from the embedded profile with Fiery X3e
CRDs, choose None as the Fiery X3e RGB Source when you print. This applies when you print directly from Photoshop, or when the same RGB EPS file is output from another application.
To override the embedded profile in an EPS file using an RGB Source definition made available by the Fiery X3e, choose anything except None as the Fiery X3e RGB Source
Profile.
Printing CMYK EPS files saved with PostScript Color Management
If you select the Photoshop PostScript Color Management option when you save a
CMYK EPS image, Photoshop embeds PostScript color information that defines the
CMYK source color space of the image. When you print a CMYK EPS file that contains PostScript color information to the Fiery X3e, CRDs are used instead of

Printing tips for advanced users
Use the following information to implement alternate, more complex, color workflows with Photoshop.
Printing RGB images with Photoshop PostScript Color Management
If you select an RGB color space and decide to use PostScript Color Management from the Photoshop pane of the printer driver, Photoshop sends RGB data to the Fiery X3e along with PostScript color information defining this RGB color space. Remember that when you select PostScript Color Management, a CRD will be used to perform color conversions to CMYK.
7
7-12 Adobe Photoshop
N OTE : The included RGB source color space information is overridden by the
Fiery X3e RGB Source option unless it is set to None. With Photoshop 5.x, the
Fiery X3e Rendering Style option specified will take effect if the Fiery X3e RGB
Source Profile option is set to None.
For fastest print times, choose JPEG encoding, but check printed output carefully for unwanted artifacts that can appear as a result of JPEG compression. If you see unexpected results in the printed output, print the job again using Binary or ASCII encoding.
Choose other print options you want to use (see Chapter 1).
Printing CMYK images with Photoshop PostScript Color Management
If you select a CMYK color space and decide to use PostScript Color Management from the Photoshop pane of the printer driver, Photoshop sends CMYK data to the
Fiery X3e along with PostScript color information defining this CMYK color space.
Remember that when you select PostScript Color Management, a CRD will be used to perform color conversions to the CMYK color space of the Fiery X3e.
The destination color space for the CRDs is determined by the RGB Separation print option. If RGB Separation is set to to Simulation, the CMYK image is printed according to all specified CMYK Simulation Profile and CMYK Simulation Method settings. If RGB Separation is set to Output, the CMYK image is converted to the
CMYK color space of the selected output profile.
Choose other print options (see Chapter 1). The Spot Color Matching setting has no
effect because Photoshop converts PANTONE colors to CMYK values when you work in CMYK mode.
• If the image was separated for an offset press standard, apply the corresponding
CMYK Simulation setting. For example, if the image is separated for SWOP, choose
SWOP as the CMYK Simulation setting.
• If Photoshop is configured for a custom separation using ICC profiles, select the corresponding profile from the CMYK Simulation print option for the Fiery X3e.
7
7-13 Photoshop 4.x
N OTE : The above custom simulation setting requires that the same profile used for separation in Photoshop also resides on the Fiery X3e. For more information on downloading CMYK Simulation profiles to the Fiery X3e with ColorWise Pro Tools,

A special feature of Photoshop allows you to save RGB EPS (PostScript) images that include independent source color space information. This feature is sometimes referred to as “PostScript Level 2 tagging” or “RGB tagging.”
You define the source color space to apply to RGB EPS images by specifying a Monitor
Setup in Photoshop. However, this Photoshop-specific source color space definition is overridden by the RGB Source print option setting located in the Print dialog box
under Printer Specific Options, unless you set the latter to Off (see page 1-6).

• When you print RGB images, you can choose whether a color conversion is performed by the Fiery X3e using a CRD or by Photoshop using Photoshop’s separation settings.
• When you print CMYK images, you can print composites or color separations .

• If you select Print in RGB , Photoshop sends RGB data to the Fiery X3e and a CRD performs color conversion. Choose the appropriate print option settings for RGB
N OTE : The Fiery X3e Rendering Style option specified will take effect if the Fiery X3e
RGB Source Profile option is set to None.
• If you select Print in CMYK , Photoshop performs a color conversion and sends
CMYK data to the Fiery X3e. With this setting, RGB Source, Rendering Style, and
Spot Color Matching settings have no effect.
For printing in CMYK, consider these Photoshop separation settings:
• If Photoshop is configured for separating to an offset press standard, apply the corresponding CMYK Simulation setting. For example, if Photoshop is configured for separating to SWOP, choose SWOP as the CMYK setting.
• If Photoshop is configured for a custom separation (not a press standard), choose
None as the CMYK Simulation setting, or choose the corresponding custom simulation profile on the Fiery X3e if one has been downloaded with the Profile
Manager. For more information on the Profile Manager and ColorWise Pro Tools,
N OTE : If you choose JPEG encoding, keep a backup of the original image saved with binary encoding until you have seen the printed results of the JPEG-encoded file.
Although not often, at times the compression used for JPEG encoding may produce unwanted artifacts in the file. If you see unexpected results in the printed output of a
JPEG-encoded file, revert to the a binary-encoded version.

Choose other print options (see Chapter 1). RGB Source and Rendering Style settings
have no effect on CMYK images. The Spot Color Matching setting is also irrelevant, because Photoshop converts PANTONE colors to CMYK values when you work in
CMYK mode.

Page Layout
Applications
8
8-1 Working with page layout applications
This chapter provides instructions for printing color documents from
Adobe PageMaker 6.5, QuarkXPress 4.02, and QuarkXPress 3.32.
Before printing from these applications, make sure the appropriate printer driver and the Fiery X3e PPD are installed on your computer, as described in Getting Started .
Working with page layout applications
The following sections apply to all page layout applications.
Defining colors
Page layout applications generally use the CMYK color model. Some allow you to define colors with other color models and may be able to send that data to the
Fiery X3e in those other color models. Generally, however, CRDs (which affect only
RGB data) do not affect colors defined in page layout applications. For predictable results with CMYK colors, use the CMYK Color Reference when defining colors in
page layout applications. See “Choosing colors in PostScript applications” on page 5-5.
N OTE : If the application allows you to define colors in RGB, you should determine whether it converts the RGB data to CMYK before sending it to the Fiery X3e. If it does, this will determine which Fiery X3e print options affect your job. For example, if the application converts RGB black (defined in the document as R0%, G0%, B0%) to four-color CMYK black when it sends the job to the Fiery X3e, the Pure Black Text/
Graphics option will have no effect when you print the job.
You can also choose named colors from the PANTONE color library. See “PANTONE
Coated Color Reference” on page 5-7.
8
8-2 Page Layout Applications
Importing images
EPS and TIFF are the recommended formats for images imported into page layout documents. Support for importing other file formats may be provided by individual applications.
All RGB images placed in a document are affected by the RGB Source and
Rendering Style settings. The Fiery X3e color management system applies the specified
RGB Source setting to all RGB data and then uses the specified Rendering Style
(CRD) to perform a color conversion. An exception to this occurs if you assign ICC
color conversion of the image and sends CMYK data to the Fiery X3e.
N OTE : To take advantage of RGB Source and Rendering Style settings for images imported into QuarkXPress 4.02, either save images in the EPS format, or use Quark
PrintRGB XTension, which outputs RGB TIFF image files without converting them to CMYK.
Tips for advanced users
If you place multiple RGB images, some non-photographic and some photographic, a single CRD may not be suitable for all the images. In this case, you may want the photographic images to bypass the CRD altogether. To accomplish this, separate the image to CMYK data with a pixel-editing application such as Photoshop and perform color correction. Save the file as an EPS or TIFF file and import it into the document.
8
8-3 Working with page layout applications
If your application supports this feature, you can save the RGB image in TIFF format and assign it an ICC profile and rendering intent when you import it into the document.
CMYK simulation
You can specify a CMYK Simulation and a CMYK simulation method for the job with the CMYK Simulation Profile and CMYK Simulation Method print options (see
page 1-8). The CMYK Simulation setting affects all CMYK color data sent by the page
layout application. It can also affect RGB data if RGB Separation is set to Simulation.
• If the document contains CMYK images that were separated for an offset press standard, apply the corresponding CMYK Simulation setting. For example, for images separated for SWOP, choose SWOP as the CMYK Simulation setting.
If you print separations to the Fiery X3e and choose use the Combine Separations feature in conjunction with Full Simulation, the result may not match that of the same page printed as composite.
• If the document contains CMYK images that were separated according to the color characteristics of a custom ICC profile (not a press standard profile), choose the corresponding profile as the CMYK Simulation Profile print option on the
Fiery X3e.
N OTE : To achieve the workflow described above, the profile used for the separation of CMYK images in the document should also reside on the Fiery X3e. For more information on downloading CMYK Simulation profiles to the Fiery X3e with
ColorWise Pro Tools, see Chapter 4.

8-4 Page Layout Applications
Adobe PageMaker 6.5 for Mac OS and Windows
The Mac OS and Windows versions of PageMaker 6.5 are essentially the same. The illustrations in this section show only the Windows version, except where differences exist between the two versions.
Windows version requirement
For the Windows version of PageMaker 6.5, make sure a copy of the Fiery X3e PPD file is in both of the following folders:
• PM65\RSRC\USENGLSH\PPD4
• Windows\System
Importing images
All RGB images placed in a document are affected by your RGB Source and Rendering
Style settings. For best results with placed images, follow the instructions in
“Importing images” on page 8-2 and “CMYK simulation” on page 8-3.
N OTE : We recommend that you use ColorWise color management rather than the
CMS options built into PageMaker. It is important that you do not use both systems for the same print job. To turn off PageMaker 6.5 color management features, choose
File>Preferences>General, then click CMS Setup and choose Off from the Color
Management pop-up menu. Click OK. Color management can be disabled for a specific bitmapped image by selecting the image and choosing Element>Image>CMS

8-7 QuarkXPress 4.x for Mac OS and Windows
QuarkXPress 4.x for Mac OS and Windows
If you have additional color management requirements not offered by ColorWise, you may want to consider using features offered by the Quark CMS XTension for
QuarkXPress 4.02. These features allow advanced users to control RGB to CMYK color conversions. If you plan to use these features, make sure Quark CMS XTension is installed before starting QuarkXPress. If it is not, use the Quark XTensions Manager to install it. For instructions, see your QuarkXPress documentation.
N OTE : Quark CMS converts RGB TIFF, JPEG, and PICT images to CMYK before sending color data to the Fiery X3e. RGB Source and Rendering Style settings have no effect on this data unless you use Quark PrintRGB XTension, which outputs RGB
TIFF image files without converting them to CMYK.
Importing images
With the exception of RGB images that are saved in EPS format or that use Quark
PrintRGB XTension, QuarkXPress 4.02 converts all RGB data into CMYK, even when Quark CMS XTension is disabled.
Only RGB images saved in EPS format are affected by RGB Source and Rendering
Style settings. For best results with placed images, use the instructions in “Importing

9-1 Working with illustration applications
This chapter provides instructions for using Adobe Illustrator for Windows and
Mac OS, Macromedia FreeHand for Windows and Mac OS, and CorelDRAW for
Windows and Mac OS.
Before printing from these applications, make sure the appropriate PostScript printer driver and the Fiery X3e PPD are installed on your computer, as described in
Getting Started .
Working with illustration applications
You can print directly from an illustration application or use it to create and save files that will be imported into a page layout document. To print from an illustration
application, use the printer driver and the print settings recommended in Chapter 1.
N OTE : These application notes provide instructions for printing composites only.
For instructions on printing color separations, refer to the documentation for your application.
As a general rule, use the EPS file format when saving files with an illustration application.
Defining colors
All illustration applications use the CMYK color model. While some also allow you to define colors using other color models, they all send CMYK data to the Fiery X3e.
Consequently, the RGB Source and Rendering Style settings in the PPD do not affect all colors printed from illustration applications. For predictable results with CMYK
N OTE : If you define colors in RGB and print directly from the application, the application converts the RGB data to CMYK before sending it to the Fiery X3e. This conversion determines which Fiery X3e print options affect your job. For example, if the application converts RGB black (defined in your document as R0%, G0%, B0%) to four-color CMYK black when it sends the job to the Fiery X3e, the Pure Black Text/
Graphics option in the PPD will have no effect when you print the job.
9
9-2 Illustration Applications
You can also choose named colors from the PANTONE color library. See “PANTONE
Coated Color Reference” on page 5-7.
Importing images
In general, all images placed in illustration application documents should be in
EPS format.
All RGB images placed in a document are affected by the RGB Source and
Rendering Style settings in the PPD. The Fiery X3e color management system applies the specified RGB Source setting to all RGB data and then uses the specified
Rendering Style (CRD) to perform a color conversion to CMYK. An exception to this occurs if you assign ICC profiles to RGB images using the application’s color
management tools (see “Tips for advanced users” below). In this case, the application
performs the color conversion of the image and sends CMYK data to the Fiery X3e.
Tips for advanced users
If you place multiple RGB images, some non-photographic and some photographic, a single CRD may not be suitable for all the images. In this case, you may want the photographic images to bypass the CRD altogether. To accomplish this, separate the image to CMYK data with a pixel-editing application such as Photoshop and perform color correction. Save the file as an EPS or TIFF file and import it into the document.
You can also save the RGB image in TIFF format and assign it an ICC profile and rendering intent when you import it into the document (see the individual application notes in this chapter).
CMYK simulation
You can specify a press simulation target and press simulation method for the job with
print options (see Chapters 1). The CMYK Simulation setting affects all CMYK color
data sent by the illustration application.
• If the document contains CMYK images that were separated for an offset press standard, apply the corresponding CMYK Simulation setting. For example, for images separated for SWOP, choose SWOP-Coated as the CMYK Simulation setting.
9
9-3 Adobe Illustrator 8.x for Windows and Mac OS
• If the document contains CMYK images that were separated according to the color characteristics of a custom ICC profile (not a press standard profile), select the corresponding profile from the CMYK Simulation Profile print option on the
Fiery X3e.
N OTE : The workflow described above requires that the profile used for the separation of
CMYK images in the document also resides on the Fiery X3e. For more information on downloading CMYK Simulation profiles to the Fiery X3e with ColorWise
Adobe Illustrator 8.x for Windows and Mac OS
If you are using ColorWise color management, disable Illustrator's color management by removing the Color Conversion and Color Conversion Utilities files from the
Adobe Illustrator>Plug-ins>Extensions folder.
Defining colors
Any colors defined in Illustrator are sent to the printer in CMYK—even those defined using other color models. For best results, use the color definition methods described
in “Choosing colors in PostScript applications” on page 5-5.
Importing images
All RGB images placed in a document are affected by the RGB Source and Rendering
Style settings you select in the PPD. For best results with placed images, follow the

Saving files for importing into other documents
When saving files in Illustrator 8.x for importing into other types of documents, use the EPS file format. In Illustrator, you can save color information in both RGB and
CMYK. The Fiery X3e’s RGB Source and Rendering Style settings affect color output of RGB artwork saved in Illustrator EPS and imported into other kinds of documents
(even when both RGB and CMYK artwork exists in the same file). In the case of
Illustrator files imported into Photoshop, however, vector data from the Illustrator file is rasterized into bitmaps in Photoshop, and the final color space of the bitmap data is determined by the color mode you set in Photoshop.

Importing images
A number of file types can be imported into FreeHand 8.x, but once imported, all are treated as either EPS images, TIFF images, or editable paths. For details, see your
FreeHand documentation.
When you import an EPS image into your document, FreeHand inserts a link to the image rather than embedding the original file, resulting in a smaller file size. If the image is a CMYK EPS file, the colors print just as they would from the originating application.
N OTE : Before placing a CMYK EPS file, be sure the file was saved with Desktop Color
Separation (DCS) set to Off. If the file was saved with DCS set to On, FreeHand prints composites of the image at the low resolution used for screen viewing.
All RGB images placed in a document are affected by your RGB Source and Rendering

Appendix A:
Desktop Color
Primer
This appendix covers concepts that are basic to printing in color, including:
• The properties of color
• Printing techniques
• Using color effectively
• Raster images and vector images
• Optimizing files for processing and printing
If you are already familiar with color theory and digital color printing, you can skip to
the last section (“Optimizing files for processing and printing” on page A-10) for tips
on optimizing files for printing.
The properties of color
This section introduces concepts that are basic to color theory. You will encounter some of these concepts (such as hue, saturation, and brightness) when you work with color in applications; others provide useful background information. Color is a complex topic, so consider this a starting point for experimentation and further research.
The physics of color
The human eye can see electromagnetic radiation at wavelengths between
400 nanometers (purplish blue) and 700 nanometers (red). This range is called the visible spectrum of light. We see pure spectral light as intensely saturated or pure colors. Sunlight at midday, which we perceive as white or neutral light, is composed of light from across the visible spectrum in more or less equal proportions. Shining sunlight through a prism separates it into its spectral components, resulting in the familiar rainbow of colors (color example 1).
A
A-2 Desktop Color Primer
Like the sun, most light sources we encounter in our daily environment emit a mixture of light wavelengths, although the particular distribution of wavelengths can vary considerably. Light from a tungsten light bulb, for example, contains much less blue light than sunlight. Tungsten light appears white to the human eye, which, up to a point, can adjust to the different light sources. However, color objects appear different under tungsten light than they do in sunlight because of the different spectral makeup of the two light sources.
The mixture of light wavelengths emitted by a light source is reflected selectively by different objects. Different mixtures of reflected light appear as different colors. Some of these mixtures appear as relatively saturated colors, but most appear to us as grays or impure hues of a color.
CIE color model
In the 1930s, the Commission Internationale de l’Eclairage (CIE) defined a standard color space, a way of defining colors in mathematical terms, to help in the communication of color information. This color space is based on research on the nature of color perception. The CIE chromaticity diagram (color example 2) is a twodimensional model of color vision. The arc around the top of the horseshoe encompasses the pure, or spectral, colors from blue-violet to red. Although the CIE chromaticity diagram is not perceptually uniform—some areas of the diagram seem to compress color differences relative to others—it is a good tool for illustrating some interesting aspects of color vision.
By mixing any two spectral colors in different proportions, we can create all the colors found on the straight line drawn between them in the diagram. It is possible to create the same gray by mixing blue-green and red light or by mixing yellow-green and blueviolet light. This is possible because of a phenomenon peculiar to color vision called metamerism . The eye does not distinguish individual wavelengths of light. Therefore, different combinations of spectral light can produce the same perceived color.
Purple colors, which do not exist in the spectrum of pure light, are found at the bottom of the diagram. Purples are mixtures of red and blue light—the opposite ends of the spectrum.

Hue, saturation, and brightness
A color can be described in terms of three varying characteristics, called the HSB color model:
• Hue—tint (the qualitative aspect of a color—red, green, or orange)
• Saturation—the purity of the color
• Brightness—relative position between white and black
While the CIE chromaticity diagram (color example 2) conveys hue and saturation, a three-dimensional color model is required to add the brightness component (color example 3).
Many computer applications include dialog boxes in which you choose colors by manipulating hue, saturation, and brightness. For example, Photoshop uses a square
Color Picker (color example 4) which can be reconfigured according to your preference.
Additive and subtractive color systems
Color devices used in desktop publishing and printing simulate the range of visible colors using a set of primary colors that are combined to create other colors. There are two methods for creating a range of colors from a set of primary colors. Computer monitors and scanners are based on the additive color model . Printing technologies, including Fiery X3es and offset presses, are based on the subtractive color model .
Additive (RGB) color
Color devices that use the additive color model make a range of colors by combining varying amounts of red, green, and blue light. These colors are called the additive primaries (color example 5). White is created by adding the maximum amount of red, green, and blue light available. Black occurs wherever all three colors are absent. Grays are created by adding equal amounts of all three color together. Combining varying amounts of any two of the additive primaries creates a third, saturated hue.
A familiar device that is based on this color model is the computer monitor (color example 6). Monitors have red, green, and blue phosphors that emit varying amounts of light to display a given color. Scanners create digital representations of colors by measuring their red, green, and blue components through colored filters.

Subtractive (CMY and CMYK) color
The subtractive color model is the basis for color printing and for color photographic prints and transparencies. While the additive color model simulates the visible spectrum of color by adding light of three primary hues, the subtractive color model starts with a “white” or neutral light source containing light of many wavelengths.
Inks, toners, or other colorants are used to selectively absorb (subtract) certain wavelengths of light that otherwise would be reflected or transmitted by the media in use.
The subtractive primaries are cyan, magenta, and yellow; they absorb red, green, and blue light, respectively (color example 7). Combining any two subtractive primaries creates a new color that is relatively pure or saturated. For example, you can make red by combining magenta and yellow, which absorb green and blue light, respectively.
White occurs when no colorant is applied. Combining all three subtractive primaries in theory yields black, but due to deficiencies of cyan, magenta, and yellow colorants, combining these three primaries actually yields a muddy brown. Black colorant is added to compensate for the deficiencies of cyan, magenta, and yellow colorants.
Consequently, color printing uses four process colors : C yan, M agenta, Y ellow, and blac K (CMYK). The use of black toner helps in producing rich, solid blacks and allows for improved rendering of black text.
The CMYK colorants used in offset printing and by your Fiery X3e copier/printer are to some degree transparent. When one layer of colorant is applied on top of another, you see the effect of both. To create a range of intermediary colors, a method is required for varying the amount of each colorant that is applied. A technique called halftoning is used in offset printing, while color print devices typically use a proprietary system for applying ink or toner colors that is similar to halftoning.

Printing techniques
Until recently, most color printing was done on printing presses using one of several printing techniques— offset lithography , flexography , and gravure , to name a few.
All traditional printing techniques require lengthy preparation before a print run can take place. Short-run color printing, including Fiery X3e printing, eliminates most of this preparation. By streamlining the process of color printing, the Fiery X3e makes short print runs economically feasible.
In contemporary offset lithographic printing, digital files from desktop computers are output to an imagesetter, which creates film separations. The film is used to make a prepress proof , which is an accurate predictor of the final print job and allows you to make corrections before going to press. Once the proof is approved, the printer makes plates from the film and runs the print job on the press.

Print device Color prints
With a Fiery X3e, you simply print the file. The Fiery X3e processes the PostScript information in the file and sends four bitmaps (one each for cyan, magenta, yellow, and black) to the print engine. The ease of Fiery X3e printing makes possible experimentation that would be too costly on press, allowing unlimited fine-tuning of color and design elements.

Halftone and continuous tone devices
Halftoning is used in offset printing to print each process color at a different intensity, allowing millions of different colors to be reproduced using only the four process colors. Depending on the required intensity of a given color, toner is placed on paper in dots of different size. The grid of dots used for each toner color is called a screen.
Halftone screens are aligned to unique angles designed to eliminate interference patterns called moiré that can arise with halftoning.
Some color print devices are commonly referred to as continuous tone (or “contone”) devices. They do not use traditional halftone screen patterns and angles. Contone devices are capable of varying the intensity of individual dots.
Even if your color printing is done exclusively on the Fiery X3e, you will encounter concepts from offset printing if you use high-end graphics applications. For example, color controls in illustration applications such as Illustrator are geared toward specifying color for offset printing using process and spot colors . Many applications allow you to specify the screening used for each printing plate.
Using color effectively
The ability to print in color can greatly increase the effectiveness of your message, whether you are printing a presentation or a newsletter, or proofing an ad concept that will later be printed on press. Some potential benefits of using color include:
• Conveying information rapidly by using color cues
• Making use of the emotive aspects of different colors
• Increasing impact and message retention
Color can also be a source of distraction and discord if it is used poorly. This section outlines some tips and concepts that will prove useful as you approach designing color materials.
A
A-7 Desktop Color Primer
A few rules of thumb
Try some of the following strategies for creating successful color materials:
• Rather than applying colors indiscriminately, use color to aid comprehension. In presentations, graphs, and charts, use color to highlight patterns and emphasize differences.
• In general, fewer colors work better than many colors.
• Use red as an accent color. Red is particularly effective when used in otherwise monochromatic materials.
• Consider the tastes of your target audience when choosing colors.
• Keep a file of printed color pieces that appeal to you or strike you as effective. Refer to it for ideas when designing your own documents.
Color wheel
A color wheel (color example 8) is a helpful tool for understanding the interrelation of colors. The colors on one side of the color wheel, from magenta to yellow, appear to most people to be warm colors, while those on the other side, from green to blue, appear to be cool. The distance between two colors on the color wheel can help predict how they will appear when seen side by side.
Colors opposite one another on the wheel are called complements (color example 9), and create a striking contrast side by side. This can be the basis for a bold graphical design, but it is an effect you should use with discretion since it can be visually fatiguing. Other bold combinations to consider are split complements (a color and the two colors adjacent to its complement) and triads (three colors evenly spaced on the color wheel). Colors adjacent to one another on the color wheel result in subtle harmonies.
The color wheel simplifies color relationships for the purpose of clarity, showing only saturated or pure colors. Adding the myriad variations of each hue to the palette (more or less saturated, darker or lighter) creates a wealth of possibilities. Taking a pair of complements from the color wheel and varying the saturation and brightness of one or both colors produces a very different result from the pure complements. Combining a light tint of a warm color with a darker shade of its cooler complement often gives pleasing results. Combining a darker shade of a warm color with a light tint of its cooler complement produces an unusual effect you may like.
A
A-8 Desktop Color Primer
Once you have mastered the concept of the color wheel, you have a good framework for experimenting with color combinations. Many books targeted at graphic designers show groups of preselected color combinations. Some are organized by themes or moods, and some are based on a custom color system such as PANTONE. The more you develop a critical facility for judging color combinations, the more you will be able to trust your own eye for color. The bibliography at the back of this manual includes books on design.
Color and text
It is not a coincidence that the overwhelming majority of text you see is printed in black on white paper. Text in black on white is highly legible and is not fatiguing to read for extended periods. For many color materials, using black text on a white background and confining color to graphic elements and headings is a good choice.
Color text can add flair to documents printed on paper when used skillfully. This technique is widely used in presentations. When using color text, avoid dazzling text and background combinations created from primary complements, especially red and cyan or red and blue; they are visually fatiguing and hard to read. Color text is more legible when distinguished from its background by a difference in lightness—for example, dark blue text on a light beige background. In addition, using many different colors in a string of text makes for a confused appearance and is hard to read. However, using a single highlight color is an effective way to draw the reader’s eye to selected words. See color example 10 for color text samples.
When using color text, keep in mind that small font sizes typically do not print in color with the same sharpness as in black. In most applications, black text prints exclusively in black toner, while color text usually prints with two or more toners.
Any misregistration between the different toners on paper causes color text to lose definition. You can make test prints to find the smallest point size at which color text prints clearly. When using high-end graphics applications that allow you to specify color as percentages of cyan, magenta, yellow, and black, you can create pure cyan or pure magenta text that prints with the same sharpness as black text. (Pure yellow text is extremely hard to read on anything but a dark or complementary background.)

Raster images and vector images
Two broad categories of artwork can be printed from a personal computer to a color printer: raster and vector images (color example 11).
A raster image , also referred to as a bitmap, is composed of a grid of pixels , each assigned a particular color value. The grid, when sufficiently enlarged, resembles a mosaic made from square tiles. Examples of raster images include scans and images created in painting or pixel-editing applications, such as Photoshop and Painter.
The amount of data found in a raster image depends on its resolution and bit depth .
The resolution of a raster describes the compactness of the pixels and is specified in pixels per inch (ppi). The bit depth is the number of bits of information assigned to each pixel. Black and white raster images require only one bit of information per pixel.
Grayscale images require 8 bits per pixel. For photographic quality color, 24 bits of
RGB color information are required per pixel, yielding 256 levels of red, green, and blue. For CMYK images, 32 bits per pixel are required.
When printing raster artwork, the quality of the output depends on the resolution of the source raster. If the raster resolution is too low, individual pixels become visible in the printed output as small squares. This effect is sometimes called “pixelation.”
In vector images , picture objects are defined mathematically as lines or curves between points—hence the term “vector.” Picture elements can have solid, gradient , or patterned color fills. Vector artwork is created in illustration and drawing applications such as Illustrator and CorelDRAW. Page layout applications such as QuarkXPress also allow you to create simple vector artwork with their drawing tools. PostScript fonts are vector-based as well.
Vector artwork is resolution-independent; it can be scaled to any size and resolution without danger of pixels becoming visible in printed output.

Optimizing files for processing and printing
The following sections provide tips on how to create image files that produce the highest possible print quality while minimizing the processing time and disk space they require.
Resolution of raster images
While a 72 ppi raster image appears sharp on a monitor, the same image would likely appear pixelated when printed to the Fiery X3e. Color print devices are capable of much greater detail than monitors, and require correspondingly higher resolution image files. However, high-resolution files can be large, and therefore cumbersome to transmit over a network, process for printing, store on disk, and edit.
Beyond a certain threshold, a higher image resolution greatly increases file size while having a minimal effect on output quality. The optimal image resolution depends on the resolution of the final print device. Aim for the resolution that optimizes both file size and output quality.
The resolution of a raster image, along with its bit depth and physical dimensions, determine its file size. The following table shows the file sizes of color raster images at different dimensions and resolutions.

In this table, the shaded areas indicate that 200 ppi is typically the best trade-off between image quality and file size. However, higher resolutions (for example,
250 to 300 ppi) may be needed for offset printing, when quality is of the utmost importance, or for images containing sharp diagonal lines.
A
A-11 Desktop Color Primer
To find the best image resolution for your purposes, make test prints of some raster artwork at different resolutions. Start with a high-resolution image (400 ppi) and save versions at progressively lower resolutions, down to 100 ppi, using a pixel-editing application such as Photoshop. Always save a copy of the original high-resolution version in case you need to revert to it. The high-resolution data cannot be recreated from a lower resolution version.
Print the files and examine the output. You will likely begin to see a marked deterioration in output quality at resolutions below 200 ppi, while above 200 ppi the improvement may be very subtle.
Image quality
100 ppi 200 ppi 300 ppi 400 ppi
Image resolution

Raster images prepared for offset printing may need to be at higher resolutions than needed for proofing on your Fiery X3e.
A
A-12 Desktop Color Primer
Scaling
Ideally, each raster image should be saved at the actual size, and it will be placed into the document at the optimal resolution for the print device. If the image resolution is correct for the print device, there is no quality advantage to be gained by scaling an image down to a percentage of its actual size. If you scale a large image down to a percentage of its actual size, you incur unnecessary file transfer time because the image data for the entire large image is sent to the printer. If an image is placed multiple times at markedly different sizes in a document, save a separate version of the image at the correct size for each placement.
If you need to place an image at greater than 100% in a document, remember that the output image resolution is affected. For example, if you scale a 200 ppi image to
200%, the image is printed at 100 ppi.

Appendix B:
Color
Management
This appendix provides information on controlling and managing color output in order to achieve predictable color results. It also discusses the basics of color management.
Controlling printed color
When working with color materials, whether they be presentations, illustrations, or complicated page designs, you make aesthetic decisions about the colors you use. Once you have decided on your goal, you then need to realize it in print. Your color printing system becomes an ally in this creative process to the extent that results are predictable .
• If you designed a poster to print on the Fiery X3e, you want the printed colors to match the design specification.
• If you are printing presentations on the Fiery X3e, you want to preserve the vivid colors you see on your monitor.
• If you are working with color that will be printed on an offset press, you want the
Fiery X3e output to match other prepress proofs or PANTONE color swatch books.
The type of print job and the final print device, Fiery X3e or offset press, determine the methodology you use to achieve the best results.
No matter what your goals are, two factors always impact color print output: print device consistency and the range of colors the device can print, known as its gamut.
These concepts are covered briefly in this chapter. Creating successful color documents and presentations also requires an understanding of color management software as it is implemented by the Fiery X3e and on your desktop computer. Most of this chapter is devoted to discussing the various elements of color management that contribute to predictable color results.

Maintaining copier/printer consistency
The factors described below affect print device consistency as well as color fidelity and overall output quality.
Paper stock and toner
The paper and toner used by your copier/printer can greatly affect printed color. For best results, use the supplies recommended by the manufacturer of the copier/printer.
Maintenance
Problems such as streaking and insufficient or excessive amounts of one or more toners arise when a copier/printer does not receive periodic maintenance or needs major repairs. In addition to having it serviced regularly, monitor the condition of your copier/printer by making standard test prints at regular intervals. You can do this easily by printing the Fiery X3e Test Page. Save the prints and show them to the service technician whenever output densities vary from the norm or other problems appear.
Print device gamut
Different color reproduction techniques have different color capabilities, or gamuts .
Color transparency films have comparatively large gamuts, as do color monitors. The color gamut that can be produced using process inks or CMYK toners on paper is smaller. This is why some colors that can be displayed on a color monitor, especially bright saturated colors, cannot be reproduced exactly by your Fiery X3e copier/ printer—nor, for that matter, can they be reproduced on a press using process colors.
Moreover, different print devices have different gamuts—some colors that your copier/ printer can produce cannot be reproduced on an offset press, and vice versa. The following illustration provides a graphical representation of this concept.
B
B-3 Color Management
You need to account for the gamut of your print device when designing on a color monitor. When printed, colors that fall outside the print device gamut are “mapped” to printable colors. This process, referred to as gamut mapping , takes place when color data is converted or adjusted to meet the gamut requirements of a print device.
The Fiery X3e is specially designed to perform gamut mapping at high speed with high quality results. It provides these color management features automatically, using either built-in default settings or settings that you specify for a particular print job. For added flexibility, the Fiery X3e color management system can also be used in combination with color management systems on Windows and Mac OS computers.
Basics of color management
The past several years have seen progress toward standardization in the field of digital color management systems. Both the Windows and Mac OS operating systems now support a standard format developed by the International Color Consortium (ICC).
This ICC format is implemented on Windows 95/98/Me, Windows NT 4.0, and
Windows 2000 computers in Image Color Matching (ICM) and on Mac OS computers in ColorSync. More and more software developers are also incorporating color management systems into high-end applications. The Fiery X3e color management system, ColorWise, supports this industry standard profile format.
A color management system, or CMS, is a “translator” between the color space of the source image (the monitor, or a scanner, for example) and the color space of the output device. The CMS uses a device-independent color space, such as CIELAB, as its intermediate color space. To perform its translation, the CMS needs information about the color space of the source image and the gamut of the print device. This information is provided in the form of profiles, often created by the makers of the monitor or print device. The end product of a CMS conversion is a printed document or an image file in the gamut of a particular device.
N OTE : If color matching between computer display and printed output is critical, you should calibrate your monitor as well as your printer. For most users, predictability of printed color output is adequate and monitor calibration is not necessary. For information on monitor calibration, see your Photoshop or Illustrator documentation.
B
B-4 Color Management
Color conversion
Before a color document can be printed, the color data in it must be converted to the gamut of the print device. Whether performed by the Fiery X3e or by a host-based
CMS, the process of converting color data for a print device is the same: the CMS interprets RGB image data according to a specified source profile and adjusts both
RGB and CMYK data according to a specified output profile, also called a destination profile by some color management systems.
Color management system
Source profile
Device-independent color space
Output profile
Input data Printed data or file
The source profile defines the RGB color space of the image’s source—characteristics such as the white point, gamma, and type of phosphors used. The output profile defines the gamut of the output device. The Fiery X3e (or the host-based CMS) uses a device-independent color space to translate between the source color space and the color space of the output device.
The Fiery X3e allows you to specify default and override settings for the source color
space information and the output profile information (see page 1-1). When you use
these settings, you do not need to use the features of other color management systems.
Your Fiery X3e software includes ICC profiles for use with other color management systems, if you choose to use them, although conflicts may arise when the Fiery X3e
CMS is used in conjunction with a host CMS.
Color management systems can also be used to adjust color data to the gamut of a print device other than the one to which you are printing. This process of simulating another print device is commonly used for proofing jobs that will print on an offset
press. The Fiery X3e simulation feature is described on page 1-8.

C-1 Importing densitometer measurements
Appendix C:
Importing densitometer measurements
This appendix describes Simple ASCII File Format, which can be used to import density measurements from measurement devices. To use your own measurement data from an alternate densitometer, record your individual readings in a text file and structure it as described below.
Simple ASCII Import File Format (SAIFF)
This format describes Status T measurement data and is for import into the
ColorWise Pro Tools Calibrator. There are three possible file formats:
• 1D Status T density for EFI 34 patch page
• 1D Status T density for EFI 21 patch page
• 1D Status T density for other pages (maximum of 256 patches per ink)
The file format is ASCII and has no tabs. A single space or multiple spaces are used as delimiters. Blank lines are not allowed. Each line in the file represents four patches (C,
M, Y, K) of a specific ink value. Comments may be on any line in the file, and these lines start with a pound sign (#) followed by a space. A line with a pound sign followed by any character other than a space has been reserved. Comments must be on an entire line by themselves.
Each line of data contains five values. The first number is the sequential patch number
(for EFI 34 and EFI 21 pages) or the ink value percentage (for other pages). The following four values are the density values of C, M, Y, and K of the corresponding patch. Lines are ordered either by increasing sequential patch numbers or by increasing the ink percentage.
For Windows computers, the file extension must be .cm1. For Mac OS computers, the file type must be ‘TEXT’.
Measurement data in EFI 34 and EFI 21 are paper-relative. For other pages, if the first line corresponds to zero ink value, the Calibrator assumes that the measurement data is absolute and adjusts it to become paper-relative by subtracting the density values of the first line from the remaining patches.

Graphics and display technology used by computers running Windows. GDI applications rely on GDI (rather than the PostScript language) to send text and pictures to copier/printers.
G-4 Glossary
GIF (Graphics Interchange Format)
A standard developed by CompuServe for bitmap graphics of up to 256 colors and used for posting photographic images on the Internet or intranet pages; rarely used for professional printing.
gradient
A smooth transition between two different colors or between two shades of a color.
Graphics Device Interface
See GDI.
Graphics Interchange Format
See GIF.
gravure
A printing technology that uses an etched cylinder that has been immersed in ink. The ink that remains in the etched areas is applied to the paper. The non-etched surfaces of the cylinder are non-printing areas. halftoning
A method for representing an original continuous tone image using a pattern of dots, lines or other patterns.
HSB
A color model where each color is represented by its hue, saturation, and brightness components; supported by most color applications.
ICC profile
An industry standard color profile format developed by the International
Color Consortium (ICC) that describes the color capabilities, including the gamut, of a color device based on the differences between an ideal and the current device. The ideal is often provided by the manufacturer as a color reference file. ICC profiles are implemented on Mac OS computers in ColorSync and on Windows 95/98,
Windows NT 4.0, and Windows 2000 computers in Image Color Matching
(ICM). The Fiery X3e’s color management system, ColorWise, supports ICC profiles.
imagesetter
Raster-based film output device; a highresolution laser output device that writes bitmapped data onto photosensitive paper or film.
JPEG
A graphics file format defined by the
Joint Photographic Experts Group committee of ISO (International
Standards Organization); a standard for digital compression of still image graphic data.
metamerism
Phenomenon in which two colors composed of different combinations of light wavelengths appear identical under a specific light source, but may look different under other light sources. The colors are called “metamers.”
G-5 Glossary moiré
An undesirable pattern in images made using halftone screens. Moiré can be caused by the improper line frequency of the screens, improper screen angles, improper alignment of halftone screens, or by the combination of a halftone screen with patterns in the image itself.
named color
A color that is defined according to a custom color system. For example,
PANTONE 107 C is a named color.
office applications
Software applications commonly used for business purposes, including presentation applications, spreadsheets, and word processing programs. offset lithography
Printing in which ink is transferred from printing plates to a rubber blanket and then from the blanket to paper.
output profile
The output profile describes the color characteristics of a printing device. It consists of both a profile for your copier/ printer and a calibration target that defines the expected density response of the copier/printer. phosphor
Material used in making computer monitors; phosphors glow and emit red, green, and blue light when struck by an electron beam, thus creating an image.
photographic rendering
A color rendering style that preserves tonal relationships in images.
Unprintable colors are mapped to printable colors in a way that retains differences in lightness, sacrificing color accuracy as necessary.
pixel
The smallest distinct element of a raster image. The term is a combination of the words “picture” and “element.”
PostScript
A device-independent page description language developed by Adobe, which is used to print and display pictures and text. PostScript 3 includes many enhancements to older versions of Post-
Script, including improved image quality and color with Enhanced Image Technology, faster performance with
Advanced Page Processing, and ease of use and setup with NetWorks System.
PPD (PostScript Printer Description file)
A file containing information about a particular PostScript print device’s capabilities and restrictions. The information in the PPD is presented via the printer driver.
prepress proof
A print made from a set of film separations or other file to simulate the results of printing. A prepress proof is the last opportunity to catch problems before the print job goes to press.
G-6 Glossary presentation graphics rendering
A color rendering style that creates saturated colors but does not match printed colors precisely to displayed colors. It is appropriate for bright saturated colors used in illustrations and graphs.
process colors
The four ink colors used in printing to simulate full-spectrum color images:
Cyan, Magenta, Yellow, and blacK
(CMYK).
QuickDraw
Graphics and display technology built into Mac OS computers. QuickDraw applications rely on QuickDraw (rather than the PostScript language) to send text and pictures to copier/printers.
raster image
Electronic representation of a page or image using a grid of points called pixels. rendering intent
The style of color rendering, or gamut mapping, designed for a particular type of color job. An example of a rendering intent is Photographic rendering—also referred to as Image rendering or
Contrast rendering—which is designed for photographic images.
resolution
The number of pixels per inch (ppi) in a bitmap image or the number of dots per inch (dpi) that a device can render.
RGB
An additive color model that makes a range of colors by combining red, green, and blue light, called the additive primaries. Commonly used to refer to the color space, mixing system, or monitor in color computer graphics.
simulation profile
The simulation profile describes the color characteristics of another print device, such as a printing press, that you want the Fiery X3e to simulate. solid color rendering
A color rendering style intended for use when color accuracy is crucial.
Unprintable colors are mapped to the closest printable colors. Solid color rendering does the best job of preserving the saturation of displayed colors.
source color space
The color environment of the originating source of an image, including scanners and color monitors. source profile
A profile used by the color management system to determine the characteristics of the color values specified in a source digital image.
spectral light
The wavelengths of electromagnetic radiation emitted by a given light source that can be seen by the human eye.
G-7 Glossary spot color
A color that is printed on its own separation plate when separations are specified. A spot color is printed using a custom ink for that color, in contrast to process colors that are printed using combinations of cyan, magenta, yellow, and black.
Status T
A spectral response for graphic arts reflection densitometers defined by
ANSI (the American National Standards
Institute).
subtractive color model
A system in which color is produced by combining colorants such as paint, inks, or dyes on media such as paper or transparent film or acetate. All printing devices use the subtractive color model.
subtractive primaries
Cyan, magenta, and yellow colorants used in subtractive color systems for color printing. Combining the subtractive primaries produces darker colors. Black is added to the subtractive primaries to compensate for deficiencies of the toners or inks, and for more efficient black printing.
substrate
In printing, the material upon which the job is printed.
SWOP
The abbreviation for Specifications for
Web Offset Publications. A standard of specifications for separations, proofs, and color printing on a web offset press ( not a sheet fed press).
undercolor removal
In areas where all three process colors (C,
M, Y) overprint, the amounts of those colors are reduced and replaced by black.
This improves wet ink trapping and reduces ink costs in process color printing.
vector image
Graphic illustration created on computers where picture objects are defined mathematically as lines or curves between points. These mathematical definitions are interpreted by an image language such as PostScript. Vector images include artwork created with illustration applications (such as
Illustrator or FreeHand) and page layout applications (such as PageMaker). white point
The color temperature of any white light source, typically expressed in degrees
Kelvin (for example, 6500 K, typical for the white of a monitor).
workflow
The path a print job follows from creation to destination. A workflow may originate with an RGB scan imported to the client workstation and opened on the desktop in an image processing application, such as Photoshop. After adjustments are made to the scanned image, it is evaluated on a color proofing device for eventual color printing on the same device or on press.
