11 About this manual
Introduction
This manual explains how to manage color output on the Fiery, and provides information on calibration and color profiles.
This manual is part of a set of documentation that includes manuals for users and system administrators. The other manuals are available at your site—refer to them for a complete description of your Fiery.
N OTE : The term “Fiery” is used in this manual to refer to the Fiery Network Controller for C9800. The name “Aero” is used in illustrations to represent the Fiery. The term
“Windows” is used to refer to Windows 98, Windows Me, Windows NT 4.0,
Windows 2000, Windows XP, and Windows Server 2003, wherever appropriate.
Illustrations of Windows software may not necessarily reflect the version of Windows that you use.
About this manual
This manual is organized to supply you with key information about managing the color output of your Fiery.
•
describes the Fiery print options and how to get the best color results.
•
covers various methods of calibrating the Fiery.
•
discusses the features of ColorWise Pro Tools. ColorWise Pro Tools include Profile Manager, used to manage color profiles on the Fiery, and Color
Editor, which allows you to customize simulation and output profiles. This chapter also describes Spot-On ® , which allows you to define CMYK equivalents for spot colors. Spot-On ® is a utility supplied with C9800 GA only. It is not available for standard models.
•
Appendix A provides information about setting up and calibrating color
measurement instruments.
•
describes the Simple ASCII File Format (SAIFF), which can be used to import toner density measurements from measurement devices.
C9800 Color Guide - 11
12 Introduction
• The Fiery Color Reference Glossary defines words in bold—for example, output profile—that appear throughout this manual. Color terms and concepts, such as
“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, check the
Glossary.
Key features of ColorWise
ColorWise is the color management system (CMS) built into the Fiery and designed to provide both casual and expert users with the best color output for a variety of purposes. The ColorWise default settings provide high-quality out-of-box color from many Windows and Mac OS applications. This allows casual users to achieve quality output without knowing about or changing any color settings on the Fiery.
For consistent color, calibrate the Fiery on a regular basis. ColorWise Pro Tools include an easy-to-use calibrator, which allows you to calibrate using a spectrophotometer or
densitometer (see Chapter 2 ).
ColorWise features allow you 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 and other spot 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.
C9800 Color Guide - 12
13 Key features of ColorWise
• Define the source of incoming RGB color data for better screen matching and provide for better color conversion of RGB data with no source information.
• Define whether RGB data is converted into the full gamut of the printer or whether it is first converted into the gamut of another device, such as a press standard. This feature is 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.
ColorWise color management (ColorWise) offers an open color architecture, allowing users to customize the Fiery to meet new printing needs as they arise. ColorWise supports ICC profiles, which are industry standard color profiles that describe the color behavior of a device. Downloading ICC profiles to the Fiery enables the Fiery to simulate a custom press (or another printer), as well as accurately print colors from a particular monitor or a scanner. In addition, you can create customized ICC profiles for the printer.
ColorWise also allows you to use any Status T densitometer by importing data in a standard file format (see
Appendix B ). In this case, it is important to note that the
quality of the instrument used will determine the quality of the calibration.

1-14 Managing color on the Fiery
The following sections describe the options available from the ColorWise color management system and explain how to customize the color settings for your particular needs. They provide descriptions of the preset ColorWise default settings and cover additional options for users who need to customize ColorWise.
For information on PostScript Level 2 or 3 printer drivers, see
. The section also contains information on the capabilities of printer drivers and instructions for setting color options with the PostScript drivers for Windows and Mac OS computers.
Managing color on the Fiery
To modify printing behavior, do any of the following:
• Select ColorWise options for an individual print job using menus that appear in the printer driver.
• Select most ColorWise options as server defaults from the “Color Setup” application in ColorWise Pro Tools (see
). Defaults can also be set from Fiery Setup, as described in the Configuration Guide Chapter 4. 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
), CMYK Simulation Method (see page 1-24
),
Appear in Driver as (see page 3-61
), default Source Profile (see page 1-22 ), RGB
Separation (see
), and associated calibration set (see
Applications can generate color data for the Fiery 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 allows users to control the printing of these mixed-color documents with features that apply specifically to
RGB, CMYK, or spot color data. Fiery color management generates CMYK data to be sent to the printer.

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 color, RGB Source Profile affects all
CIEBasedABC color spaces (if the source space is RGB). If you send CMYK data to the Fiery in CIEBasedDEFG format, for example, by choosing PostScript Color
Management in Adobe Photoshop, the Fiery Rendering Style selection—which normally affects only RGB data—will also affect this CMYK data.

N OTE : When RGB Separation is set to Simulation, RGB colors are affected by
CMYK Simulation Profile and CMYK Simulation Method.
Applies an RGB source space definition to RGB data (see page 1-22
). If you choose the Other setting, you must also specify particular settings for Gamma,
Phosphors, and White Point. See the corresponding options in this table. This option, along with Gamma, Phosphors, and White Point, only affects
DeviceRGB or calibrated RGB color spaces.
The On setting enables Fiery-defined matching of spot colors to their best
CMYK equivalents. With Spot-On, you can manage and edit these spot color matches (see
page 3-70 ). Off instructs the Fiery to match color output to a
CMYK combination specified by the source application for the document (see
).
Detailed explanations of how these and other settings affect your print jobs are provided in subsequent sections of this chapter.

Rendering Style
The Rendering Style option specifies a CRD for color conversions. To control the appearance of images, such as prints from office applications or RGB photographs from Photoshop, select the appropriate Rendering Style. The Fiery allows you to select from the four rendering styles currently found in industry standard ICC profiles.
Fiery 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 and digital camera images.
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 color of a monitor will map to neutral gray. You may prefer this style to avoid visible borders when not printing full-bleed.
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.
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.
Relative Colorimetric
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.

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, leave this option set to On. When Pure
Black Text/Graphics is on, black colors generated by applications (for example, RGB =
0, 0, 0; CMYK = 0%, 0%, 0%, 100%; or K = 100%) are printed using the maximum amount of black toner allowed by the calibration curve. This means the black text and line art will not exhibit halftone artifacts (as long as the printer is calibrated correctly) and will not be misregistered, since there is only one toner used. In addition, this setting eliminates blasting.
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 : Use the Pure Black Text/Graphics option only when printing composites, not when printing separations.

With the default profile, prints a rich black using all toners.
Prints only with black toner, because CMYK simulations preserve the black channel. The actual amount of toner used depends on the current simulation and the calibration state of the printer.
Prints only with black toner, because spot color simulations preserve the black channel. The actual amount of toner used depends on the current simulation and the calibration state of the printer.
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. 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 3 driver for Windows
2000/XP. To print this single-color black at the maximum toner density of the printer, set the Pure Black Text/Graphics option to On.

1-20 Fiery Color Management
Black Overprint
The Black Overprint option allows you to specify whether or not black text or text/graphics—defined as RGB = 0, 0, 0, or as CMYK = 0%, 0%, 0%, 100%— overprints colored backgrounds.
• Text —Black text overprints colored backgrounds, eliminating white gaps and reducing halo effects or misregistration of colors.
• Text & Graphics —Black text and graphics overprint colored backgrounds, eliminating white gaps and reducing halo effects or misregistration of colors.
• Off —Black text or text/graphics knocks out colored backgrounds.
N OTE : PostScript applications may perform their own black overprint conversions before sending the print job to the Fiery.
One example of how you might use this setting is with a page that contains 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 set to Text or Text & Graphics, the final text or text/graphic portions of the page are overprinted, or combined with the underlying colors. Black colors generated by applications (for example, RGB = 0%, 0%, 0%; CMYK = 0%,
0%, 0%, 100%) are printed using the maximum amount of black toner allowed by the calibration curve. This means that black text and line art will not exhibit halftone artifacts (as long as the printer is calibrated correctly). 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 or text/graphics. 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 or text/graphics 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). This transition may cause visible artifacts because of the practical limitations of the printer.
C9800 Color Guide - 20

1-21 Managing color on the Fiery
Spot Color Matching
The Spot Color Matching option provides automatic matching of spot colors with their best CMYK equivalents.
• On —The Fiery uses a built-in table to generate the closest CMYK matches of spot colors your printer can produce. (New tables are generated when you add new output profiles.) With Spot-On, the Fiery uses the CMYK matches determined through Spot-On (see
).
• Off —The Fiery uses CMYK equivalents defined by the spot color manufacturer, such as PANTONE. These are the same CMYK equivalents used by applications that include spot color libraries.
For jobs that include 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
).
For PDF jobs that include spot colors and where the spot colors are not included in the built-in table, setting Spot Color Matching to On retains the spot color originally specified. The Fiery references the built-in table to generate the closest CMYK matches of the original spot color.
N OTE : 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 in the Fiery Color Reference
Chapter 4 ) prints differently depending on the Spot Color Matching setting.
• On —The Fiery uses a built-in table or, with Spot-On, the Spot-On color dictionaries
(see
) to generate the best matches of the PANTONE colors that your
C9800 can produce. The PANTONE number is printed below each swatch.
• Off —The Fiery prints swatches using the CMYK values recommended by Pantone
Inc. (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.
C9800 Color Guide - 21

1-22 Fiery Color Management
RGB Source Profile
The RGB source profile setting allows you to define the characteristics of the RGB data in your document so the appropriate color conversion can occur on the Fiery.
Commonly used monitor color spaces are available from the printer driver and from the ColorWise Pro Tools Profile Manager. For special needs, 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 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 output from the Fiery is consistent across platforms. The Fiery 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 computer 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 Profile setting, you must 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 page 3-58 .
If you are printing with the PostScript driver from a Windows computer and have
Two-Way Communication enabled, the name of each downloaded profile is represented in the RGB Source Profile setting menu. If you are printing with the
AdobePS driver from a Mac OS computer, downloaded profiles appear as Source-1 through Source-10. For more information on Two-Way Communication, see
Chapter 1 of the User Software Installation Guide .
C9800 Color Guide - 22

1-23 Managing color on the Fiery
• None instructs the Fiery 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.
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
). Non-PostScript RGB data and PostScript RGB data that does not contain a source color space definition are converted using a general undercolor removal (UCR) conversion method.
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.
With the Windows printer drivers, you can also view an unlimited number of custom
Full simulations created using ColorWise Pro Tools. On Mac OS computers, you can view up to 10 Full custom simulations. The number of custom simulations is limited by the disk space on the Fiery.
If you are printing with the PostScript driver from a Windows computer and have
Two-Way Communication enabled, the name of each downloaded or custom profile is represented in the CMYK Simulation Profile setting menu. If you are printing with the
AdobePS driver from a Mac OS computer, downloaded or custom profiles appear as
Simulation-1 through Simulation-10. For more information on Two-Way
Communication, see the User Software Installation Guide Chapter 1 .
The None setting sends your original CMYK data to the printer in its calibrated state, without conversions to simulate another printer.
The CMYK Simulation Profile setting you 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 with the CMYK Simulation Profile setting.
• For images that were separated for SWOP, choose SWOP as the CMYK Simulation
Profile setting.
C9800 Color Guide - 23

1-24 Fiery Color Management
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. For more information about downloading ICC profiles to the Fiery, see
“Downloading profiles” on page 3-58.
CMYK Simulation Method
The CMYK Simulation Method allows you to define your preferred
CMYK-to-CMYK conversion technique.
• Quick applies one-dimensional transfer curves to adjust output densities in the cyan, magenta, yellow, and black channels. This technique leads to pleasant color output from your printer because pure primary colors are not “contaminated” by other colorants. While it is the fastest simulation method and perfect for drafts, avoid using it for final documents that will be used as press proofs. Other techniques offer more color simulation accuracy, which is expected by proofing applications.
• Full (Source GCR) provides a complete and accurate simulation based on colorimetric transformations. Hues are preserved, even for primary colors. The Gray Component
Replacement (GCR) level that was specified in the original (source) document is also preserved. Full (Source GCR) is therefore an excellent simulation technique for the highest quality press proofing applications.
• Full (Output GCR) is also a complete and accurate simulation method based on colorimetric transformations. Hues are preserved, even for primary colors. With this method, the Gray Component Replacement (GCR) level that was specified in the original document is not preserved. Instead, all CMYK data is reseparated using the
GCR level specified by the Output Profile. This simulation technique is similar to traditional ICC color matching methods and is appropriate for most documents designed for the press, but reproduced on your C9800.
N OTE : When you specify On for Pure Black Text/Graphics, and specify Full (Output
GCR) for CMYK Simulation Method, the black text and graphics in your document are printed with 100% black-only toner.
C9800 Color Guide - 24

1-25 Managing color on the Fiery
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 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 printer (see output profile) or is first converted into the gamut of another digital printer or 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 Fiery can simulate the behavior of that device.
RGB Separation is also useful for prepress applications. For example, it allows you to 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 condition. When the desired printing condition is found, convert the file to CMYK, using the same CMYK simulation profile you 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 printer (when set to the printer’s default), or a customized CMYK color space for your printer (when set to Output 1-10).
• Simulation converts all RGB colors into the CMYK color space for a specified simulation (select the desired simulation with the CMYK Simulation Profile print option).

Output profile
An output profile consists of a profile for your printer, describing its color characteristics.
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
you do so, the new customized output profile is applied to all data in the print job.
Changing the output profile does not affect its associated calibration target (since the target is based on a printer model). You can edit D-Max values of the calibration target
Use the ColorWise Pro Tools Profile Manager to download your own output profile to
the Fiery (see page 3-58 ). Downloaded output profiles are at first associated with the
calibration target that is tied to the default output profile. You can edit calibration target D-Max values separately.
If you are printing with the PostScript driver from a Windows computer and have enabled Two-Way Communication, the name of each downloaded or custom profile is represented in the Output Profile setting menu. If you are printing with the AdobePS driver from a Mac OS computer, downloaded or custom profiles appear as Output-1 through Output-10. For more information on Two-Way Communication, see the
User Software Installation Guide Chapter 1 .
Combine Separations
The Combine Separations setting specifies how to print separated CMYK data. With
Spot-On, you can combine an unlimited number of spot color separations along with the CMYK separations.
The Combine Separations options are:
• Off prints each separation individually.
• On combines separations as a single, composite-color document and automatically makes these settings for the following print options: Color Mode (CMYK),
Rendering Style (None), Pure Black Text/Graphics (Off ), Spot Color Matching
(Off ), or Black Overprint (Off ).
For information about using the Combine Separations option with applications such as Photoshop, see the Fiery Color Reference .

Calibration
Calibrating the Fiery ensures consistent, reliable color output. This chapter explains how calibration works and provides instructions for all calibration procedures. You can calibrate the Fiery using ColorWise Pro Tools in combination with any of the following color measurement instruments:
• EFI Spectrometer ES-1000 hand-held spectrometer
• EFI Densitometer ED-100 hand-held densitometer
• X-Rite DTP41 automatic scanning spectrophotometer
• X-Rite DTP32 automatic scanning densitometer
By connecting one of these instruments to a serial or USB port on your computer, you can quickly measure calibration color patches and download measurements to the
Fiery.
N OTE : To use the ES-1000 or ED-100 with a Mac OS computer, you must connect the instrument to a USB port. For more information, contact your service technician/representative. For information on setting up and operating the DTP41
.
For information on advanced calibration and simulation features available with
ColorWise Pro Tools, such as editing profiles and creating custom profiles, see
Chapter 3 . A format for inputting color measurements from other densitometers is
described in
.
N OTE : The procedures described in this chapter are fundamentally the same for
Windows and Mac OS computers. The main differences are the interface cable and the port used to connect to the measurement instrument. The illustrations in this chapter describe the Windows version.
N OTE : The term computer is used to refer to any computer running ColorWise Pro
Tools.

2-34 Color Calibration
An overview of calibration
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 printer.
• Calibration sets are sets of measurements.
• A calibration target that describes the expected behavior of the printer is contained in each output profile.
After you have calibrated the Fiery, a calibration set is stored. 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.
If you change the calibration after a saved job has been processed (RIPped), you do not need to reprocess (reRIP) the job. The new calibration affects the job without a need for reprocessing.
N OTE : Changing calibration has the potential to affect all jobs for all users, so consider limiting the number of people authorized to perform calibration. Set an Administrator password in Fiery Setup to control access to calibration (see the Configuration Guide
Chapter 7 ).
C9800 Color Guide - 34

2-35 Understanding calibration
Understanding calibration
Although most users’ needs are met by the default calibration set, the Fiery allows you to choose a calibration set to customize calibration for specialized jobs.
Calibration allows you to:
• Maximize the color reproduction capabilities of the C9800.
• Ensure consistent color quality over time.
• Produce consistent output across Fiery servers.
• Achieve better color matches when reproducing spot colors, such as PANTONE colors or other named color systems.
• Optimize the Fiery for using ColorWise rendering styles (CRDs) and CMYK simulations, and for using ICC profiles.
How calibration works
Success in obtaining satisfactory print quality from the Fiery depends on many factors.
Among the most important are establishing and maintaining optimal toner densities.
The density is the measure of the light absorbed by a surface. By carefully regulating toner densities, you obtain consistent printed color.
Even with a calibrated system, toner density is affected by service settings, humidity, and temperature; density also tends to drift over time. Regular measurement detects day-to-day variations in densities, and calibration corrects for them.
Calibration works by creating calibration curves on the Fiery that compensate for the difference between actual (measured) and desired (target) density values. These calibration curves are the graphic equivalent of transfer functions, which are mathematical descriptions of changes that will be made to the initial data. Transfer functions are often graphed as input or output curves.
The Fiery 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.
C9800 Color Guide - 35

2-36 Color Calibration
Measurements
Measurement files contain numerical values that correspond to the toner density produced by the printer when it prints solid cyan, magenta, yellow, and black, and graduated tints of those colors.
To create a measurement file, print a page of color patches. Then measure the patches using a color measurement instrument connected to a computer on the network. The new measurements are automatically downloaded to the Fiery.
Output profiles and calibration sets
Output profiles and calibration sets define desired calibration results. One or more output profiles and calibration sets are provided with the Fiery. When you calibrate the
Fiery, 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 1-26
.
Scheduling calibration
In general, you should calibrate the Fiery at least once a day, depending on the volume of print jobs. If it is very important to maintain consistent color, or if the printer is subject to wide fluctuations in temperature or humidity, calibrate every few hours. For optimal 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 after printer maintenance.
N OTE : Because printed output from the printer is very sensitive to changes in temperature and humidity, the C9800 should not be installed near a window or in direct sunlight, or 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.
C9800 Color Guide - 36
2
2-37 Understanding calibration
To monitor print quality, print the following color reference pages:
• Color Charts from the Control Panel (see the Configuration Guide Chapter 4 )
• Color Charts from Command WorkStation/Command WorkStation LE (see
“Printing Fiery Information Pages” in the Job Management Guide Chapter 2 )
• Color reference pages included with the user software (see “Introduction” in the
User Software Installation Guide )
All 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. Save and compare pages you printed at different times. If there is a noticeable change in appearance, calibrate the Fiery.
When you examine the Test Page, all color patches should be visible, even though they may be very faint in the five percent and two percent range. 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 printer service technician to determine whether adjusting the printer can improve output.
Checking calibration status
To verify whether the Fiery is calibrated, which calibration set and output profile were used, and when the printer was last calibrated:
• Print a Configuration page or Test Page from the Control Panel or Command
WorkStation/Command WorkStation LE.
• Select a calibration set in Calibrator (available from ColorWise Pro Tools); the last calibration and the user who performed it are displayed.

Using Calibrator
ColorWise Pro Tools Calibrator allows you to calibrate the Fiery using the measurement method of your choice.
Changing the calibration has the potential to affect all jobs for all users, so consider limiting the number of people authorized to perform calibration. Set an Administrator password to control access to calibration (see “Setting Passwords” in the
Configuration Guide Chapter 7 ).
N OTE : Multiple users can be connected to one Fiery with ColorWise Pro Tools, but only one user at a time can use Calibrator. An error message appears if you try to calibrate when another user is using ColorWise Pro Tools to calibrate.

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.
Simulation profiles should be profiles only for those devices you want the Fiery to match in terms of color output characteristics. Output profiles should be profiles only for the printer to which you print. Although you can download CMYK printer profiles as Simulation or Output, consider how they will be used. If you want the Fiery prints to look like another printer, download that profile as a Simulation.
4.
Click the arrow to download the profile and click OK when the download is complete.
The new profile now appears in the list of profiles on the right side of the Profile
Manager main window.
For Mac OS computers, this profile must be associated with one of the predefined names (Source-1 through Source-10 for RGB Source, Simulation-1 through
Simulation-10 for Simulation, or Output-1 through Output-10 for Output) or set as the default before it can be used. For Windows computers, all profiles can appear in
the printer driver by their profile descriptions (see “Defining profiles” on page 3-61).
N OTE : When an output profile is downloaded, it inherits the calibration target of the current default output profile.
Editing profiles

Defining profiles
For Mac OS computers, before you apply any downloaded or edited profile to a print job, that profile must be linked to one of the predefined custom names, or you can set
for RGB Source, Simulation-1 through Simulation-10 for Simulation, or Output-1 through Output-10 for Output.
For Windows computers, all profiles appear by their actual names in the printer driver.
These fixed names are used in the printer driver, so you can select profiles per job even if your driver does not have the capability to obtain an updated list from the Fiery.
N OTE : A custom simulation profile is used to illustrate this procedure. The same steps apply for defining output profiles.
T O DEFINE A CUSTOM SIMULATION PROFILE
1.
Start ColorWise Pro Tools and click Profile Manager.
Custom profile created with
Color Editor
For the purposes of this example, assume DIC-new is a custom simulation profile created with Color Editor and, as such, no information is displayed for DIC-new under the heading “Appear in Driver as.”
C9800 Color Guide - 61

3-62 ColorWise Pro Tools
N OTE : You can define custom profiles only. Default profiles are predefined and cannot be changed.
2.
Select DIC-new in the Simulation list, and click Profile Settings or double-click
DIC-new.
3.
Select the “Appear in Driver as” option, choose one of the predefined custom simulation names (Simulation-1 through Simulation-10) from the menu, and then click Apply.
N OTE : Choose a name that is not already linked with another simulation. You cannot define two profiles with the same name.
N OTE : Although you cannot delete a preset profile, you can use the name of a preset profile for your edited profile when you select the “Appear in Driver as” option. This replaces the preset profile with your own profile.
In Profile Settings, you can also change profile descriptions for all non-locked profiles.
4.
Click OK.
Simulation-1 now appears under the “Appear in Driver as” column for DIC-new.
Choosing Simulation-1 from the CMYK Simulation option of the printer driver applies the DIC-new simulation to the print job.
If you do not define a custom simulation profile, your job will print with CMYK
Simulation Profile set to None. If you do not define a custom RGB Source or Output profile, the default profile is used.
C9800 Color Guide - 62

3-63 Color Editor
Considerations for defining Output Profiles
The procedures for defining Output Profiles is similar to the preceding example for defining Simulations profiles. However, note these differences:
For output profiles, the predefined custom names are Output-1 through Output-10.
When you choose Profile Settings for an output profile, the Use Calibration Set options also appear. You must calibrate the Fiery with this calibration set before this option has any effect. If you have never measured for this calibration set, default
measurements are used. For more information about calibration sets, see page 2-35 .
Color Editor
Color Editor allows you to customize simulation and output profiles. 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. Use Color Editor to fine-tune a profile on your Fiery to meet your exact specifications. For example, you can create a custom profile for printing to a specific media type.
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 —Edit output profiles and save customized versions of them.
• % Density —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 2-35 ).
C9800 Color Guide - 63

3-64 ColorWise Pro Tools
Color Editor also has several Edit Modes for editing simulations:
• Master —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 , Full (Source GCR) , or Full (Output GCR) —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, the master simulation is automatically applied. For detailed information about simulation methods, see
N OTE : If you made edits to a master simulation after you created a linked simulation, the edits are not applied to the linked simulation.

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 in any combination. Working with only one or two colors at a time allows you to fine-tune 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.
To adjust the dot gain value for simulating press output, click Dot Gain.
Choose either the North American or
European standard. Use the sliders to adjust to 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.
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).

For greater precision, type percentages in the Input and Output fields or use the arrow keys on the keyboard to adjust the curve. To use the arrow keys, you must first click the curve to establish an anchor point that serves as a reference.
9.
For an output profile, set maximum densities of the C, M, Y, and K channels.
Enter the maximum densities, called D-Max values, of individual colors for profiles that support density settings. D-Max settings are not available when you edit
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 with the new name. If you edit one of the press standard targets (for example, SWOP-Coated, DIC, or Euroscale), consider including the original name as part of the new target name (for example, DIC-new) 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.
For Mac OS computers, custom profiles must be linked to one of the ten predefined custom profile names (Simulation-1 through Simulation-10 for Simulation, or
Output-1 through Output-10 for Output) to be accessible from the printer driver.
Create as many custom profiles as you want, but a maximum of ten are available from

N OTE : When editing a simulation profile in Quick mode, clicking Import at the bottom of the Color Editor window allows you to import a custom Quick Simulation created on another Fiery using the previous version of ColorWise. The current version of ColorWise does not allow you to save custom CMYK Quick, Full (Source GCR) or
Full (Output GCR) Simulations independently; rather, they are saved as components of the same profile.
4.
Edit and save the simulation, as described in steps 5 through

For this new simulation to be automatically applied to a print job, the CMYK
Simulation, Simulation Method, and Output Profile settings must be the same as those used when you edited the profile. If the Simulation Method is different or a different output profile is selected, the Master simulation is applied.
N OTE : A CMYK Simulation Profile can have a custom Master and one or more custom links—up to three links (Quick mode and the two Full modes) for each output profile on the system. For the CMYK Simulation Profile option in the printer driver, note that if you select a custom profile for which the output ink percentage is greater than 0 and the input ink percentage is 0, the Use Master print option will have no effect.
Undoing CMYK simulation edits
You can undo the changes you made to CMYK simulations (master and linked) in the following ways:
• If you have not yet saved your edits, click Done on the Color Editor menu bar and do not save the changes.
• If you saved your edits under a new CMYK simulation name and want to delete all edits—in Master, Quick, and Full (Source GCR) or Full (Output GCR) modes—to the simulation, see

Using Spot-On
N OTE : The Spot-On utility is included with C9800 GA models only. It cannot be used with other C9800 models.
The ColorWise Spot Color Matching option automatically matches spot colors with their best CMYK equivalents so that spot colors can be simulated using the CMYK toner of the printer. However, you may want to adjust the default CMYK equivalents to achieve a better match for your specific printing conditions.
Spot-On allows you to adjust and manage lists of spot colors and their CMYK equivalents. The matching lists of spot colors and CMYK values are known as Spot
Color Dictionaries. Spot-On allows you to maintain multiple Spot Color
Dictionaries—one for each output profile on the Fiery.
N OTE : In order to use Spot-On CMYK equivalents, you must enable the Spot Color
Matching option (see
Starting Spot-On
You can start Spot-On from ColorWise Pro Tools. To work with Spot-On, you must first specify the output profile associated with the Spot Color Dictionary that you want to edit. However, you may switch to a different output profile at any time while working with Spot-On.

To update the centerpatch to a neighboring color that more closely matches the target, click the corresponding neighbor patch.
Neighboring patches represent variations from the centerpatch and can be selected if they offer a closer match to the desired color. Clicking one of these patches updates the centerpatch to the new color and provides a new selection of neighboring colors. These patches are either lightness or saturation neighbors, depending on the option you choose in the following step.
N OTE : When you select certain colors, an exclamation point icon may appear in the upper-right corner of the window. This icon indicates that the centerpatch color lies at the edge of the printer’s printable gamut and may not be reproducible.

3-79 Using Spot-On
Select either Lightness or Saturation in the Color Directions Legend.
Lightness generates neighbor patches based on darker to lighter shades of the original color. This variation is displayed from left to right, with the original color remaining in the centerof the middle group.
Saturation generates neighbor patches based on less saturated to more saturated variations of the original color. This variation is displayed from left to right, with the original color remaining in the center of the middle group.
Choose a setting from the Color Spacing menu to control the closeness of the neighbor patches.
A higher setting generates neighbor patches that differ more noticeably from the center color. As you get closer to your target color, reduce the color spacing to a smaller value.
Select Monitor Compensation to simulate how all the on-screen color patches will appear when printed on paper.
This simulation depends on the monitor profile that has been configured for the display. To specify the monitor profile, choose Preferences from the Edit menu in the

For the best color accuracy, calibrate the X-Rite DTP41 spectrophotometer every time you calibrate the Fiery. You can initiate the calibration sequence in ColorWise Pro
Tools Calibrator as part of the process of Fiery calibration. The computer may also prompt you that it is necessary to calibrate the spectrophotometer.
Alternatively, you can initiate the DTP41 calibration process using the Instrument button on the DTP41. For more information on this method, see the documentation that came with the X-Rite DTP41.

Using the X-Rite DTP32 densitometer
ColorWise Pro Tools are designed to work with the X-Rite DTP32 reflection densitometer, which feeds color measurements to the Fiery automatically.
N OTE : Measurements from other densitometers can be input using a simple ASCII file
Setting up the DTP32
Before you calibrate the Fiery using the X-Rite DTP32, you need to connect, configure, and calibrate the densitometer to prepare for measuring the printed patches
(see “Calibrating the DTP32” on page A-93). For additional information about setting
up and using the DTP32, see the separate documentation included with the densitometer.
T O CONNECT THE X-R ITE DTP32 TO THE COMPUTER
1.
Turn off the computer.
2.
Plug the square end of the interface cable (looks like a modular phone plug) into the
I/O port on the side of the X-Rite DTP32.

B-95 Importing Density Measurements
Appendix B:
Importing
Density
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 measurement instrument, record your individual readings in a text file and structure it as follows.
Simple ASCII Import File Format (SAIFF)
This format describes Status T measurement data for import into the ColorWise Pro
Tools Calibrator. The three possible file formats are:
• 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. Comment lines must 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 four values that follow 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.
