Introduction
• The Glossary defines words in bold—for example, output profile—that appear
throughout this manual. 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, check the Glossary.
Key features of ColorWise
ColorWise is the color management system (CMS) designed and 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 great out-of-box color
from many Windows and Mac OS applications. This allows casual users to achieve
good 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
a simple-to-use calibrator, which allows you to calibrate using either the scanner that
comes with the copier/printer or an optional spectrophotometer or densitometer
(see Chapter 2).
ColorWise features let you 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.
• 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 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.
xiii
Key features of ColorWise
ColorWise color management (ColorWise) offers an open color architecture, letting
users 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 copier/printer), as well as accurately print colors
from a particular monitor or a 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 B). In this case, it is important to note that the quality of the
instrument used will determine the quality of the calibration.

Chapter 1:
Fiery Color
Management
Managing color on the Fiery
The first part of this chapter describes the options available from the ColorWise
color management system and explains how to customize the color settings for your
particular needs. It provides descriptions of the preset ColorWise default settings and
covers additional options for users who need to customize ColorWise.
Beginning on page 1-14 is a detailed explanation of what a PostScript Level 2 or 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 and
Mac OS computers.
Managing color on the Fiery
To modify the Fiery’s 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 page 3-37). Defaults can also be set from Fiery 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 1-9), Simulation Method (see page 1-10), Appear in
Driver as (see page 3-8), default Source Profile (see page 1-7), RGB Separation
(see page 1-8), and associated calibration set (see page 2-4).
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 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 Color Management
Fiery color management generates CMYK data to be sent to the copier/printer.
The following diagram illustrates the print options in the Fiery color management
process that affect color data conversions. You access these print options when you
send a print job to the Fiery. 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 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.

Managing color on the Fiery
Settings for the following options can be specified via print options when you send a
job to the Fiery. Some can also be set as defaults by the administrator during Fiery
Setup or using ColorWise Pro Tools. Settings specified via print options override the
defaults.

(Default set at Setup)
Quick simulation applies one-dimensional transfer curves that adjust output
density only. The Full simulations apply colorimetric transformations that
adjust hue as well as output density (see page 1-10).
Adjusts color output to compensate for the white point value of the paper
stock used. This option is only available as part of the Fiery Graphic Arts
Package feature set.
The output profile is applied to all data in the print job (see page 1-10).
User-defined output profiles can be downloaded to the Fiery using
ColorWise Pro Tools (see Chapter 3).

What it does
The On setting overprints black text placed on colored backgrounds; it
automatically activates the Pure Black Text/Graphics option (see page 1-11).
Black Overprint
On/Off (Default set at Setup)
Specifies whether black overprinting should apply to text only or to both text

be set to On (see page 1-11).
Black Overprint Style
Text/Text & Graphics
The On setting enables Fiery-defined matching of spot colors to their best
CMYK equivalents. If you have the Fiery Graphic Arts Package option
installed, you can use Spot On to manage and edit these spot color matches
(see page 3-22). Off instructs the Fiery to match color output to a CMYK
combination specified by the source application for the document (see
page 1-13).

Detailed explanations of how these and other settings affect your print jobs are
provided in subsequent sections of this chapter.
Combine Separations
The Combine Separations setting specifies how to print separated CMYK data. If you
have the Fiery Graphic Arts Package option, 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 constrains the
settings of the following print options: Color Mode (CMYK), Rendering Style
(None), Pure Black Text/Graphics (Off ), Spot Color Matching (Off ).
EX12
• 1–PgAutomatic combines separations as a single, composite-color document,
overprinting plates in the order defined by the source application.

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 Adobe Photoshop. The Fiery allows you to
select from the four rendering styles currently found in industry standard ICC profiles.

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

Managing color on the Fiery
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.
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
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 will be 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 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 page 3-4.
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 pop-up 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 the User Software Installation Guide.

Fiery Color Management
• 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 page 1-6). 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.
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 copier/printer (output) 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 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
condition. When the desired printing condition is found, you can then 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 copier/printer
(when set to the printer’s default), or a customized CMYK color space for your
copier/printer (when set to Output 1-10).
1
1-9
Managing color on the Fiery
• 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).
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 9x/Me or Windows NT printer driver, you can also view an
unlimited number of custom Full simulations created using ColorWise Pro Tools.
On Windows 2000/XP and 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 pop-up 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.
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.
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 3-4.

1-10
Fiery Color Management
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 in the cyan,
magenta, yellow, and black channels.
• Full (Source GCR) provides a more complete and accurate simulation by applying
colorimetric transformations that adjust the hue as well as output density of the
cyan, magenta, and yellow channels. This option preserves the black amount
determined by the simulation profile. Choose this option if you are printing a
color proof to simulate output from a device represented by the simulation profile.
• Full (Output GCR) applies the same simulation method as Full (Source GCR), but
preserves the black amount determined by the output profile. Choose this option if
you are printing final output on the Fiery.
You should choose one of the Full options if you are printing an image separated using
an optimized black generation (UCR/GCR) setting, either from a scan or from within
an application such as Photoshop.
Output profile
The output profile is applied to all data in the print job, so make sure the selected
profile is the right one 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 3-10).
If you do so, the new customized output profile is applied to all data in the print job.
Changing the output profile only does not affect its associated calibration target
(since the target is based on a copier/printer model). You can edit D-Max values of the
calibration target separately (see page 3-6).
1
1-11
Managing color on the Fiery
You can use the ColorWise Pro Tools Profile Manager to download your own output
profile to the Fiery (see page 3-4). 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.
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 pop-up 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.
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.

Spot
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
copier/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 copier/printer, set the Pure Black Text/Graphics option to On.
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.
1
1-13
Managing color on the Fiery
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 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). This transition may cause visible artifacts because of the practical
limitations of the copier/printer.
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 copier/printer can produce. (New tables are generated when you add
new output profiles.) If you have the Graphics Art option installed, the Fiery uses
the CMYK matches determined through Spot On (see page 3-22).
N OTE : Spot colors not included in the built-in table are treated as CMYK.
• 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 page 1-9).
N OTE : You can use the Spot Color Matching option only when printing composites,
not when printing separations.

Fiery Color Management
Spot Color Matching and the PANTONE Coated Color Reference
The PANTONE Coated Color Reference (described in the Fiery Color Reference)
prints differently depending on the Spot Color Matching setting.
• On—The Fiery uses a built-in table or, if you have the Fiery Graphic Arts Package
option, the Spot On color dictionaries (see page 3-22) 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 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.
PostScript printer driver for Windows and Mac OS
You can access the printer driver options described in this section by choosing
Start\Settings\Printers, right-clicking the appropriate PPD name, and choosing
Properties (Windows 9x/Me), Document Defaults (Windows NT), or Printing
Preferences (Windows 2000/XP) from the pop-up menu. To access the Mac OS driver
options, choose Print from the File menu of your application. These settings are also
accessible from the Print Setup or Page Setup dialog boxes of most applications.
For Windows computers, the Fiery 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 print options you chose. The printer driver sends the
PostScript file to the Fiery. The Fiery then performs PostScript processing and color
conversions and sends raster color data to the print device.

The AdobePS driver includes the following Color Matching options.
• Color/Grayscale—When this setting is used to print to the Fiery, ColorWise
provides all color conversions on the Fiery. Typically, you should use this option
when printing to the Fiery.
• PostScript Color Matching—Can be used with PostScript devices such as the Fiery.
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 selected.
N OTE : If you use the PostScript Color Matching option, the driver may, depending on
the application in use, attach a CMYK source definition to the CMYK data in your
document. In such a case, the CMYK data in the document is reseparated using a Fiery
CRD. The destination color space for the CRD is determined by the RGB Separation
print option. When RGB Separation is set to Simulation, CMYK data is printed
according to all specified CMYK Simulation Profile and CMYK Simulation Method
settings. When RGB Separation is set 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, but it is intended
for use with PostScript Level 1 devices. If you use this option, be sure to specify
the Fiery ICC profile as the Printer Profile. ColorSync Color Matching is not a

Color Calibration
An overview of calibration
Calibrating the Fiery ensures consistent, reliable color output. You can calibrate
the Fiery using ColorWise Pro Tools in combination with any of the following color
measurement instruments, available as separately purchased options:
• X-Rite DTP41 automatic scanning spectrophotometer
• X-Rite DTP32 automatic scanning densitometer
• EFI Densitometer ED–100 hand-held densitometer
• EFI Spectrometer ES–1000 hand-held spectrometer
By connecting the instrument to the serial port on your computer, you can quickly
measure calibration color patches and download measurements to the Fiery. For
information on setting up and operating the DTP41 and DTP32, see Appendix A.
EX12
You can also obtain measurements from the copier’s built-in scanner and calibrate
using AutoCal™ or ColorCal™, which do not require the use of a measurement
instrument and can be run from ColorWise Pro Tools or the Control Panel.
This chapter explains how calibration works and provides instructions for all
calibration procedures.
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 Appendix B.
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. This chapter shows screens and
dialog boxes for the Windows version.
N OTE : The term computer is used to refer to any computer running
ColorWise Pro Tools.

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 copier/printer.
• Calibration sets are sets of measurements.
• A calibration target that describes the expected behavior of the copier/printer is
contained in each output profile.
Once 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.
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 in Fiery Setup to control access to calibration (see the
Configuration Guide).
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 Fiery.
• Ensure consistent color quality over time.
• Produce consistent output across Fiery servers that are connected to the same
copier/printer.
• 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.
2
2-3
Understanding calibration
How calibration works
Success in obtaining satisfactory print quality from a color server such as a Fiery
connected to a copier/printer 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 can 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 data you start with.
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.
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. Then measure the
patches using either a color measurement instrument connected to a computer on the
network or, if it is available, the print device’s scanner. The new measurements are
automatically downloaded to the Fiery.
2
2-4
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. When you
calibrate the Fiery, 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 1-10.)
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
copier/printer is subject to wide fluctuations in temperature or humidity, calibrate
every few hours. For 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 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, 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.
Print color reference pages. You can print Color Charts from the Control Panel (see the
Configuration Guide) or Command WorkStation (see the Job Management Guide), and
the color reference pages included with the user software (see the User Software
Installation Guide ). 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, calibrate the Fiery.
2
2-5
Using Calibrator
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. 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 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.
• Select a calibration set in Calibrator—the last calibration and the user who
performed it are displayed.
Using Calibrator
ColorWise Pro Tools Calibrator lets you calibrate the Fiery using the measurement
method of your choice.
Changing the 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 to control access to calibration (see the Configuration Guide).
N OTE : Multiple users can be connected to one server 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 already using ColorWise Pro Tools to calibrate.

Using the EFI Spectrometer ES-1000 and
EFI Densitometer ED-100
The EFI Spectrometer ES-1000 is a hand-held spectrophotometer that measures the
spectral light reflected from printed output and other colored materials. Since the ES1000 accurately measures both the density and color of printed output, it is an
effective tool for calibrating the Fiery.
The EFI Densitometer ED-100 is a hand-held instrument that measures the density
of printed ink and toner. Like the DTP32, the ED-100 is a reflection densitometer
that you can use to calibrate the Fiery.
The ES-1000 and the ED-100 are available as separately purchased options.
Setting up the ES-1000
To use the ES-1000 for calibration purposes, you must first set it up for use with your
computer. For best results, you should also calibrate the ES-1000 itself using the white
point calibration card that is included with the instrument.
For complete instructions on setting up and calibrating the ES-1000, see the
documentation that is included with the instrument.

ColorWise Pro Tools
Simulation profiles should only be profiles for those devices you want the Fiery to
match in terms of color output characteristics. Output profiles should only be profiles
for the device to which your Fiery is connected. Although CMYK printer profiles can
be downloaded 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.
If you have a custom profile of the copier/printer your Fiery is connected to, 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 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 3-8).
N OTE : When an output profile is downloaded, it inherits the calibration target of the
current default output profile.
Editing profiles
The profiles on the Fiery can be customized to meet your specific needs and the
characteristics of your copier/printer using Color Editor, either directly or through
Profile Manager. For more information on editing profiles, see “Color Editor” on
page 3-10.

Defining profiles
For Mac OS computers, before you can 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 the profile as the default for all print jobs (see setting default profiles, page 3-3).
Ten names are available for custom profiles—Source-1 through Source-10 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 PPD so you can select profiles for each job even if
your driver does not have the capability to obtain an updated list from the server.
N OTE : A custom simulation profile is used to illustrate this procedure. The same steps
apply for defining custom or downloaded output profiles.

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. If you try to
define two profiles with the same name, you will get an error message.
For an output profile, the predefined custom names would be Output-1 through
Output-10.
N OTE : While you cannot delete a preset profile, you can use the name of a preset
profile name for your edited profile when you select the “Appear in Driver as” option.
This replaces the preset profile with your own profile.
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 will be used. For more information about calibration sets, see page 2-2.
In Profile Settings, you can also change profile descriptions for all non-locked profiles.

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.

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 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—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 2-2).
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
page 1-10.
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.

To adjust the dot gain value for simulating press output, click Dot Gain.
You can 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.

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 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, 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 10 predefined
custom profile names (Simulation-1 through Simulation-10 for Simulation or
Output-1 through Output-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 3-8.
If you are using the printer driver for Windows, custom profiles will appear in the
driver window without being associated with a predefined profile name.
If you set a custom profile as the default, you can access it from the printer driver
without linking it to one of the predefined custom names. Simply select “Printer’s
default” from the printer driver.

Using Spot On (Fiery Graphic Arts Package option)
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 copier/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 lets you maintain multiple Spot Color Dictionaries—one
for each output profile on the Fiery.

ColorWise Pro Tools
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 center patch color lies at
the edge of the copier/printer’s printable gamut and may not be reproducible. In such
cases it is recommended that you use an approximate target that lies within the gamut,
rather than the out-of-gamut color.
You can also click the center patch to enter CMYK values directly. For more
information, see the procedure on page 3-34.
3.
Use the following techniques to control how neighboring color patches are generated:
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 center of 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, you will want to 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

You can use Color Setup to set the default ColorWise settings for the Fiery. To access
Color Setup, click its icon in the ColorWise Pro Tools main window.
Setting default ColorWise options
Color Setup allows you to configure the default color management settings for the
Fiery. These settings are applied to all print jobs sent to the Fiery, unless a user
overrides them for an individual job by changing settings in the printer driver.
These default settings can also be overridden using Command WorkStation or Fiery
WebSpooler™. Color Setup maintains a connection to the Fiery, so changes made in
Profile Manager appear automatically. In addition, the defaults set in Color Setup are
automatically reflected in other Fiery tools that list default settings.
You can also reset the Fiery to its factory default settings by clicking Factory Default in
the lower-left corner of the Color Setup window.
The options in Color Setup are arranged in a pattern representing the flow of color
processing that takes place on the Fiery.

Color Measurement Instruments
This appendix explains how to set up and calibrate the following color measurement
instruments, available as separately purchased options:
• X-Rite DTP41 automatic scanning spectrophotometer
• X-Rite DTP32 automatic scanning densitometer
Using the X-Rite DTP41 spectrophotometer
ColorWise Pro Tools Calibrator supports the X-Rite DTP41 spectrophotometer, a
device that measures density and color data. The DTP41 communicates directly with
the Calibrator application in ColorWise Pro Tools, sending measurements to the Fiery
automatically.
Setting up the DTP41
Before you calibrate the Fiery, you must connect, configure, and calibrate the
spectrophotometer to prepare for measuring the printed patches. For additional
information about setting up and using the DPT41, see the documentation included
with the instrument.

Calibrating the DTP41
For the best color accuracy, you should 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.
Multiple users can be connected to one Fiery server with ColorWise Pro Tools, but
only one user at a time can use the Calibrator module. An error message appears if you
try to calibrate when another user is already using ColorWise Pro Tools to calibrate.
You will need the Color Reflection Reference strip that is included with the
spectrophotometer. Remove the strip from its protective envelope, handling it by the
edges only. Keep the strip free of dust and smudges and always store it in the protective
envelope.

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 and is 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, 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 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.

and reduces ink costs in process color
printing.
vector graphic
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
graphics include artwork created with
illustration applications (such as
Illustrator or FreeHand) and page layout
applications (such as PageMaker).
