xv Key features of ColorWise
Key features of ColorWise
ColorWise
designed to provide both casual and expert users the best color output for a variety of
purposes. The ColorWise default settings were specifically selected to provide great
out-of-box color from many applications and Windows and Mac OS platforms. This
means that casual users can get good quality output without knowing about or
changing any color settings on the Fiery X40.
To get consistent color you should be sure that the Fiery X40 is calibrated on a regular
basis. ColorWise Pro Tools include a simple-to-use calibrator, which allows you to
calibrate using optional densitometers (see Chapter 3).
There are a number of features that can be used to modify printing results. Depending
on your particular needs, you can:
• Set the behavior of CMYK printing to emulate DIC, Euroscale, and SWOP offset
press standards
• Match PANTONE colors for the best match when printed using four-color press
conditions or when printed using presses with extra, custom plates
• Select a

accurate printing of photographs; and relative or absolute colorimetric rendering for
specialized needs
is the
color management system
color rendering dictionary
(CMS) built into the Fiery X40 and
(CRD), also called a rendering style, for RGB
• Define the source of incoming RGB color data for better screen matching, and you
can provide for better color conversion of RGB data with no source information
• Define whether RGB data is converted into the full gamut of the copier 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
xvi Introduction
ColorWise offers an open color architecture, letting users customize the Fiery X40 to
meet new printing needs as they arise. ColorWise supports ICC profiles, which are
industry standard color profiles that define the color behavior of a device. By downloading ICC profiles to the Fiery X40, it can simulate a custom press (or another
copier) as well as accurately print colors from a particular monitor or a particular scanner. In addition, you can create customized ICC profiles for the copier.
ColorWise also lets you use any Status T densitometer by importing data in a standard
file format (see Appendix C). In this case, it is important to note that the quality of the
instrument used will determine the quality of the calibration.

Chapter 1:
Fiery X40 Color
Management
The first part of this chapter describes the options available from the ColorWise color
management system and explains how you can customize the color settings for your
particular needs. It provides descriptions of the preset default settings of ColorWise
and covers additional options for users who need to customize ColorWise.
Beginning on page 1-13 is a detailed explanation of what a PostScript Level 2 or
PostScript 3 printer driver does, as well as information on the capabilities of various
printer drivers and instructions for setting color options with the PostScript drivers for
Windows NT 4.0, Windows 2000, Windows 95/98, and Mac OS.
Managing color on the Fiery X40
There are three ways to modify the Fiery X40’s printing behavior:
• You can select ColorWise options for an individual print job using menus that
appear from the printer driver.
• You can select most ColorWise options as server defaults from the Color Setup
application in ColorWise Pro Tools (see page 4-23). Defaults can also be set from
Fiery X40 Setup or from the Control P anel, as described in the
These defaults will apply to all subsequent print jobs unless you override them.

• You can select some ColorWise options, particularly default
and calibration options, from ColorWise Pro Tools. These options include default
Simulation Profile (see page 1-8), Simulation Method (see page 1-9), Appear in
Driver as (see page 4-8), default Source Profile (see page 1-6), RGB Separation (see
page 1-7), and associated calibration set (see page 3-3).
Applications can generate color data for the Fiery X40 in many different
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 X40 lets users control
the printing of these mixed-color documents with features that apply specifically to
RGB, CMYK, or spot color data.
Fiery X40 color management generates CMYK data to be sent to the copier; additional
processing may then be performed before printing begins.

Quick simulation applies one-dimensional transfer curves that adjust output
density only. Full simulation applies colorimetric transformations that adjust
hue as well as output density (see page 1-9).
The Output Profile is applied to all data in the print job (see page 1-9). Userdefined output profiles can be downloaded to the Fiery X40 with
ColorWise Pro Tools (see Chapter 4).
The On setting optimizes the quality of black text and line art output (see
page 1-10).
The On setting overprints black text placed on colored backgrounds; it
automatically activates the Pure Black Text/Graphics option (see page 1-11).
The On setting enables Fiery X40 matching of PANTONE colors; Off
instructs the Fiery X40 to match color output to a Pantone-specified CMYK
combination (see page 1-12).

Rendering styles
The Rendering Style option specifies a CRD for color conversions. You can modify the
Rendering Style option to control the appearance of images, such as prints from office
applications or RGB photographs from Photoshop . The Fiery X40 lets you select from
the four rendering styles currently found in industry standard ICC profiles.

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 X40. 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 R GB Source P r ofile, the F iery X40
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 ov erride 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 X40 will be
consistent across platforms. Below are the Fiery X40’s RGB Source Profile options.
• 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, y ou can choose settings for the Gamma, Phosphors, and White
Point options.
• Sources 1-10 specify the definitions you download as RGB source profiles. (For
more information about downloading RGB source profiles, see Chapter 4.)
If you are printing with the PostScript driver for Windows 95/98 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 or Windows NT computer, or the Micr osoft P ostScript driver
from a Windows 2000 computer, downloaded profiles appear as Source-1 through
Source-10. For more information on two-way communication, see Getting Started.
1-7 Managing color on the Fiery X40

• None instructs the Fiery X40 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, R GB 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 1-5). NonPostScript RGB data and PostScript RGB data that does not
contain a source color space definition is converted using a general undercolor
removal conversion method.
RGB Separation
The RGB Separation option determines how RGB colors (as well as Lab and XYZ
colors) are converted to CMYK. The name of this option is meant to be descriptive,
since the option defines the color spaces that will be used by the Fiery X40 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 (Output) or whether it is first converted into the
gamut of another digital printer or a press standard (Simulation). This feature is
helpful for making one device behave like another for RGB data. For example, if a
high-quality ICC profile is available for another print device, the copier can simulate
the behavior of that device.
RGB Separation is also useful for prepress applications. For example, it lets you
experiment with the appearance of an RGB scan under different press printing
conditions without having to convert the RGB data to CMYK data for each printing
condition. When the desired printing condition is found, you can then convert the file
to CMYK, if desired, using the same CMYK simulation profile that was used during
the experimentation.
NOTE: The RGB Separation print option should be used in conjunction with the
Output Profile or CMYK Simulation Profile print options.
• Output converts all R GB colors into the CMYK color space of your copier (when the
Output Profile option is set to P rinter ’s default), or a customized CMYK color space
for your copier (when the Output Profile option is set to Output 1-10).
1-8 Fiery X40 Color Management

• 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 95/98 printer driver, you can also view an unlimited number of
custom Quick and Full simulations created using ColorWise Pro Tools. On Windows
NT, Windows 2000, and Mac OS computers, you can view up to 10 Quick and 10
Full custom simulations. The number of custom simulations is limited by the disk
space on the Fiery X40.
If you are printing with the PostScript driver for Windows 95/98 and have two-way
communication enabled, the name of each downloaded or custom profile is
represented in the CMYK Simulation P rofile setting pop-up menu. I f you ar e printing
with the AdobePS driver from a Mac OS or Windo ws NT computer, or the Microsoft
PostScript driver from a Windows 2000 computer, downloaded or custom profiles
appear as Simulation-1 through Simulation-10. For more information on two-way
communication, see Getting Started.
The CMYK Simulation Profile setting you should specify depends on the press
standard for which the CMYK data was separated.
• For images that were separated using a custom separation (such as a separation
produced with an ICC profile), choose the corresponding profile on the Fiery X40
with the CMYK Simulation Profile setting.
• For images that were separated for SWOP, choose SWOP as the CMYK Simulation
Profile setting.
NOTE: 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 X40. F or mor e information
about downloading ICC profiles to the Fiery X40, see “Downloading profiles” on
page 4-5.
1-9 Managing color on the Fiery X40

• The Match Copy setting bypasses Fiery X40 calibration to simulate the color of a
copy produced by the copier. Use this setting when you print images scanned with
the Fiery Scan plug-in set to Match Copy.
CMYK Simulation Method
The CMYK Simulation Method setting specifies the quality of simulation to perform.
• Quick applies one-dimensional transfer curves that adjust output density only.
• Full provides a more complete and accurate simulation by applying colorimetric
transformations that adjust hue as well as output density. The Full Simulation
option also maintains the integrity of the black channel by adjusting it
independently. This is especially important for images separated using an optimized
black generation (UCR/GCR) setting either from a scan or from within an
application such as Photoshop.
Output Profile
The output profile is applied to all data in the print job, so make sure the selected
profile is right for your job. The default output profile consists of both a profile for
your copier, describing its color characteristics, and a calibration target that describes
the expected behavior of the copier.
In certain cases you may wish to customize the default output profile using
ColorWise Pro Tools’ Color Editor to achieve particular color effects (see page 4-12).
If so, the new customized output profile is applied to all data in the print job.
Changing only the output profile does not affect its associated calibration target (since
the target is based on a copier model). If you wish, you can edit D-Max values of the
calibration target separately (see page 4-7).
You can also use ColorWise Pro Tools’ Profile Manager to download your own output
profile to the Fiery X40 (see page 4-5). Downloaded output profiles are at first
associated with the calibration target that is tied to the default output profile. As
mentioned above, you can edit calibration target D-Max values separately.
If you are printing with the PostScript driver for Windows 95/98 and have two-way
communication enabled, 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 or Windows NT computer, or the Microsoft

PostScript driver from a Windows 2000 computer, downloaded or custom profiles

communication, see Getting Started.
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
the On position. 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 turn this option Off, for example, if the page includes
gradient fills that use black. The table below describes the behavior of the Pure Black
Text/Graphics option with black data defined in different color spaces.
NOTE: The Pure Black Text/Graphics option can be used only when printing
composites, not when printing separations.

NOTE: 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 X40.
These elements are not affected by the Pure Black Text/Graphics option. See the
application notes for details. Also, black text and line art defined as RGB = 0, 0, 0 in
office applications (such as Microsoft Word) are converted to single-color black
(CMYK = 0%, 0%, 0%, 100%) by the Microsoft PostScript Level 2 driver for
Windows NT 4.0. To print this single-color black at the maximum toner density of the
copier, 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.
NOTE: PostScript applications may perform their own black overprint conversions
before sending the print job to the Fiery X40.
One example of how you might use this setting is with a page that contains some black
text on a light blue background. The background blue color is CMYK = 40%, 30%,
0%, 0% and the black text is CMYK = 0%, 0%, 0%, 100%.
• With Black Overprint On, the final text portions of the page are overprinted, or
combined with the underlying colors. This results in CMYK = 40%, 30%, 0%,
100% for the color used for the text. There is no transition in the cyan and magenta
toners, and the quality of the output is improved since it will not show artifacts near
the edges of the text. The option also works with text defined in the RGB color
space, that is RGB = 0, 0, 0.
• With Black Overprint Off, the border of the text is on an edge that has cyan and
magenta toners on one side (outside the text) and black toner on the other side
(inside the text). On many devices, this transition causes visible artifacts because of
the practical limitations of the copier.
1-12 Fiery X40 Color Management

Spot Color Matching
The Spot Color Matching option provides automatic matching of PANTONE colors
with their best CMYK equivalents.
• On—The Fiery X40 uses its built-in table to generate the closest CMYK matches of
PANTONE colors your copier can produce. (New tables are generated when you
add new output profiles.)
• Off—The Fiery X40 uses the CMYK equivalents defined by your application to
print PANTONE colors.
For jobs that include PANTONE spot colors, set Spot Color Matching to On unless
you are printing press simulations. In that case, set Spot Color Matching to Off and
choose the appropriate CMYK Simulation setting (see page 1-8).
NOTE: You can use the Spot Color Matching option only when printing composites,
not when printing separations.
Spot Color Matching and the PANTONE Coated Color Reference
The PANTONE Coated Color Reference (described on page 5-7) prints differently
depending on the Spot Color Matching setting.
• On—The Fiery X40 uses its built-in table to generate the best matches of the
PANTONE colors that your copier can produce. The PANTONE number is
printed below each swatch.
• Off—The Fiery X40 prints swatches using the CMYK values recommended by
Pantone (and used by applications that provide PANTONE color libraries). The
CMYK values used to generate the color, as well as the PANTONE number of the
color, are printed below each swatch. These CMYK values are printed through the
selected CMYK Simulation and Output Profile settings.

Printer Drivers and Print Options
This section describes the role of the printer driver and explains how to use Windows
and Mac OS printer drivers for Fiery X40 printing.
NOTE: The term “PostScript” by itself is used to refer to Adobe PostScript Level 2 or
later.
What a printer driver does
To take full advantage of the features of the Fiery X40, your print jobs must be sent as
PostScript data. Since most applications cannot generate PostScript data directly, it is
the function of a printer driver to interpret instructions from the application and
convert them to PostScript data.
A PostScript printer driver also allows you to select print options specific to your
copier. To do this, the printer driver must be matched with a PostScript printer
description file (PPD) for your Fiery X40. The PPD contains information about the
particular features supported by the Fiery X40 and the copier. The PPD can be
thought of as the lines of PostScript code in the file that ar e device-specific. When you
print a job, the printer driver lets you choose among features by displaying print
options.
A few PostScript applications can send PostScript data directly to the copier and
present print options within the application interface. Even these applications,
however, require that you use a PostScript printer driver.
Your Fiery X40 user software includes Adobe PostScript printer drivers for
Windows 95/98, Windows NT 4.0, and Mac OS and the Microsoft PostScript printer
driver for Windows 2000. These are the recommended printer drivers for printing to
the Fiery X40. (See Getting Started for information on installing printer drivers.)
It is recommended that you set the print options initially in Fiery X40 Setup (see the
Configuration Guide). This provides you with a default configuration that is
appropriate for most Fiery X40 print jobs.
1-14 Fiery X40 Color Management

PostScript printer driver for Windows 95/98, Windows NT 4.0,
and Windows 2000
The printer driver options described in this section can be accessed by clicking
Start\Settings\Printers, right-clicking the appropriate PPD name, and selecting
Properties (Windows 95/98), Document Defaults (Windows NT), or Printing
Preferences (Windo ws 2000) from the pop-up menu. These settings are also accessible
from the Print Setup or Page Setup dialog boxes of most applications.
For W indow 95/98, the Fiery X40 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 P ostScript file containing the instructions generated by your
application and the Fiery X40 print options you selected. The printer driver sends the
PostScript file to the Fiery X40. The Fiery X40 then performs PostScript processing
and color conversions and sends raster color data to the print device.
NOTE: The following illustrations and instructions do not apply to all applications.
Many applications, such as PageMaker, Photoshop, Illustrator, QuarkXPress, and
CorelDRAW, have other color management options in addition to those presented in
the printer driver. For information on specific applications, see Chapters 6 through 9.
