xix Key features of ColorWise
Key features of ColorWise
ColorWise
is the
color management system
(CMS) built into the Fiery X3e and
designed to provide both casual and expert users the best color output for a variety of
purposes. The ColorWise default settings were specifically selected to provide great
out-of-box color from many applications and Windows and Mac OS platforms. This
means that casual users can get good quality output without knowing about or
changing any color settings on the Fiery X3e.
To get consistent color you should be sure that the Fiery X3e is calibrated on a regular
basis. ColorWise Pro Tools include a simple-to-use calibrator, which allows you to
calibrate using either the scanner that comes with the copier or optional densitometer
(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
color rendering dictionary
(CRD), also called a rendering style, for RGB
printing. CRDs allow for rich, saturated printing of presentation graphics; smooth,
accurate printing of photographs; and relative or absolute colorimetric rendering for
specialized needs
• Define the source of incoming RGB color data for better screen matching, and you
can provide for better color conversion of RGB data with no source information
• Define whether RGB data is converted into the full gamut of the copier 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.
xx Introduction
ColorWise offers an open color architecture, letting users customize the Fiery X3e to
meet new printing needs as they arise. ColorWise supports ICC profiles, which are
industry standard color profiles that define the color behavior of a device. By
downloading ICC profiles to the Fiery X3e, it can simulate a custom press (or another
copier) 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.

1-1 Managing color on the Fiery X3e
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 X3e
There are three ways to modify the Fiery X3e’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 Fiery X3e Setup or
from the Control Panel, as described in the
Configuration Guide
. These defaults will
apply to all subsequent print jobs unless you override them.
• You can select some ColorWise options, particularly default
ICC profile
settings
and calibration options, from ColorWise Pro Tools. These options include default
Simulation Profile (see page 1-8), Appear in Driver as (see page 4-8), default Source
Profile (see page 1-6), and associated calibration set (see page 3-4).
Applications can generate color data for the Fiery X3e in many different
color spaces
.
The most common type of color data produced from office applications is RGB, while
prepress applications generally produce CMYK data. Desktop applications can also
generate spot colors such as PANTONE colors. To complicate matters, a single page
may contain a mix of RGB, CMYK, and spot colors. The Fiery X3e lets users control
the printing of these mixed-color documents with features that apply specifically to
RGB, CMYK, or spot color data.
Chapter 1:
Fiery X3e Color
Management
1
1-2 Fiery X3e Color Management
Fiery X3e color management generates CMYK data to be sent to the copier; additional
processing may then be performed before printing begins.
The diagram below illustrates the print options in the Fiery X3e color management
process that affect color data conversions. You access these print options when you
send a print job to the Fiery X3e. Most of these options and settings are described in
subsequent sections of this chapter.
RGB Source Profile is the only color option that applies strictly to RGB color data.
The other options that affect RGB color also affect the more rarely used Lab, XYZ, and
other calibrated color spaces.
N
OTE
:
For users who are familiar with PostScript 3.0 color, RGB Source Profile affects
all CIEBasedABC color spaces (if the source space is RGB). Also, if you send CMYK
data to the Fiery X3e in CIEBasedDEFG format, for example, by choosing PostScript
Color Management in Adobe Photoshop, the Fiery X3e’s Rendering Style selection—
which normally affects only RGB data—will also affect this CMYK data.

1-3 Managing color on the Fiery X3e
Settings for the following options can be specified via print options when you send a
job to the Fiery X3e. Some can also be set as defaults by the administrator during
Fiery X3e Setup. Settings specified via print options override the defaults.
Fiery X3e color print option: What it does:
Brightness
85% Lightest to 115% Darkest
Performs a color adjustment on all color channels to make the printed output
lighter or darker.
Rendering Style
Photographic/Presentation/Relative
Colorimetric/Absolute Colorimetric
(Default set at Setup)
Applies a Fiery X3e color rendering style (CRD) to RGB data (see page 1-5),
or to any incoming data with a PostScript source color space definition,
including CMYK.
RGB Source Profile
EFIRGB/sRGB (PC)/Apple Standard/Other/
Source 1–10/None
(Default set at Setup or with
ColorWise Pro Tools)
Applies an RGB source space definition to RGB data (see page 1-6). If you
choose the Other setting, you can 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, are the only
ColorWise options that affect only DeviceRGB or calibrated RGB color spaces.
(Other) Gamma
1.0/1.2/1.4/1.6/1.8/2.0/2.2/2.4/2.6/2.8/3.0
Applies the specified gamma value to the RGB source space definition (see
page 1-6). To use this print option, you must choose Other as the RGB Source
setting.
(Other) Phosphors
Hitachi EBU/Hitachi-Ikegami/NTSC/
Radius Pivot/SMPTE/Trinitron
Applies the specified phosphor (monitor type) information to the RGB source
space definition (see page 1-6). To use this print option, you must choose
Other as the RGB Source setting.
(Other) White Point
5000 K (D50)/5500 K/6500 K (D65)/
7500 K/9300 K
Applies the specified white point value to the RGB source color space
definition (see page 1-6). To use this print option, you must choose Other as
the RGB Source setting.
RGB Separation
Output/Simulation
Determines which CMYK color space your original RGB data will be
separated into—CMYK for the copier (Output) or CMYK for a specified
simulation (Simulation) (see page 1-7). It is important to note that when RGB
Separation is set to Simulation, RGB colors are affected by CMYK Simulation
Profile and CMYK Simulation Method.
CMYK Simulation Profile
SWOP-Coated/DIC/Euroscale/Simulation
1–10/Match Copy/None
(Default set at Setup or in
ColorWise Pro Tools)
Adjusts CMYK color data to simulate an offset press standard or a custom
color gamut defined at your site. The Match Copy setting bypasses Fiery X3e
calibration to match a copy made from the copier glass. Choosing None
bypasses simulation (see page 1-8).
N
OTE: Some of the Simulation settings have slightly different names depending
on the model of copier.

1-4 Fiery X3e Color Management
Detailed explanations of how these and other settings affect your print jobs are
provided in subsequent sections of this chapter.
CMYK Simulation Method
Quick/Full
(Default set at Setup or in
ColorWise Pro Tools)
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 1-8).
Output Profile
default output profile/Output 1–10
(Default set at Setup or in
ColorWise Pro Tools)
The Output Profile is applied to all data in the print job (see page 1-9). User-
defined output profiles can be downloaded to the Fiery X3e with
ColorWise Pro Tools (see Chapter 4).
Pure Black Text/Graphics
On/Off
(Default set at Setup)
The On setting optimizes the quality of black text and line art output (see
page 1-9).
Black Overprint
On/Off (Default set at Setup)
The On setting overprints black text placed on colored backgrounds; it
automatically activates the Pure Black Text/Graphics option (see page 1-11).
Spot Color Matching
On/Off
(Default set at Setup or with
ColorWise Pro Tools)
The On setting enables Fiery X3e matching of PANTONE colors; Off
instructs the Fiery X3e 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 X3e lets you select from
the four rendering styles currently found in industry standard ICC profiles.
Fiery X3e rendering style: Best used for:
Equivalent
ICC rendering
style:
Photographic—Typically results in less
saturated output than presentation
rendering when printing out-of-gamut
colors. It preserves tonal relationships
in images.
Photographs, including scans and
images from stock photography CDs.
Image,
Contrast, and
Perceptual
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.
Artwork and graphs in presentations.
In many cases it can be used for mixed
pages that contain both presentation
graphics and photographs.
Saturation,
Graphics
Relative Colorimetric
—Provides
white-point transformation between
the source and destination white
points. For example, the bluish gray of
a monitor will map to neutral gray.
You may prefer this style to avoid
visible borders when not printing full-
bleed.
Advanced use when color matching is
important but you prefer white colors
in the document to print as paper
white. It may also be used with
PostScript color management to affect
CMYK data for simulation purposes.
Same
Absolute Colorimetric
—Provides no
white point transformation between
the source and destination white
points. For example, the bluish gray of
a monitor will map to a bluish gray.
Situations when exact colors are
needed and visible borders are not
distracting. It may also be used with
PostScript color management to affect
CMYK data for simulation purposes.

1-6 Fiery X3e Color Management
RGB Source Profile
The RGB Source Profile setting allows you to define the characteristics of the RGB
data in your document so that the appropriate color conversion can occur on the
Fiery X3e. Commonly used monitor color spaces are available from the driver and
from the ColorWise Pro Tools Profile Manager. In addition, for special needs you can
use ColorWise Pro Tools to download custom monitor or scanner profiles.
When you specify a setting other than None for the RGB Source Profile, the Fiery X3e
overrides source color space definitions or profiles that other color management
systems may have specified. For example, if you specified a ColorSync System Profile
on your Mac OS computer, the RGB Source Profile setting overrides it. In cases where
you do not want this setting to override another specified source color space, choose the
None setting.
When you specify a setting other than None for the RGB Source Profile—since the
color space definitions are overridden—the prints from the Fiery X3e will be consistent
across platforms. Below are the Fiery X3e’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, you can choose settings for the Gamma, Phosphors, and White
Point options.
• Sources 1-10 specify the definitions you download as RGB source profiles. (For
more information about downloading RGB source profiles, see Chapter 4.)
• None instructs the Fiery X3e to allow the RGB sources you defined elsewhere, such
as in the application, to be used. When you set RGB Source to None, the
appearance of colors will not be independent of the file type. For example, RGB EPS
files will look different from RGB TIFF files.
1
1-7 Managing color on the Fiery X3e
With RGB Source set to None, PostScript RGB data that contains a source color
space definition is converted using the CRD specified by the Rendering Style option
(see page 1-5). 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 X3e to
“separate” the RGB data into CMYK values.
The two choices available for this option determine whether RGB data is converted
into the full gamut of the copier (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 RGB colors into the CMYK color space of your copier (when the
Output Profile option is set to Printer’s default), or a customized CMYK color space
for your copier (when the Output Profile option is set to Output 1-10).
• Simulation converts all RGB colors into the CMYK color space for a specified
simulation (make sure to select the desired simulation with the CMYK Simulation
Profile print option).

1-8 Fiery X3e Color Management
CMYK Simulation Profile
The CMYK Simulation Profile print option allows you to print press proofs or
simulations. This setting specifies the offset press standard or other color printing
device that you want to simulate. This option affects CMYK data only.
You can view up to 10 Quick and 10 Full custom simulations from the printer driver.
The number of custom simulations is limited by the disk space on the Fiery X3e.
The CMYK Simulation Profile setting you should specify depends on the press
standard for which the CMYK data was separated.
• For images that were separated using a custom separation (such as a separation
produced with an ICC profile), choose the corresponding profile on the Fiery X3e
with the CMYK Simulation Profile setting.
• For images that were separated for SWOP, choose SWOP as the CMYK Simulation
Profile setting.
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 X3e. For more information
about downloading ICC profiles to the Fiery X3e, see “Downloading profiles” on
page 4-5.
• The Match Copy setting bypasses Fiery X3e calibration to simulate the color of a
copy produced by the copier. 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.

1-9 Managing color on the Fiery X3e
Output Profile
The output profile is applied to all data in the print job, so make sure the selected
profile is right for your job. The default output profile consists of both a profile for
your copier, 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 X3e (see page 4-5). Downloaded output profiles are at first
associated with the calibration target that is tied to the default output profile. As
mentioned above, you can edit calibration target D-Max values separately.
Pure Black Text/Graphics
The Pure Black Text/Graphics option affects the printout for black text and vector
graphics on a page. Under most circumstances it is preferable to leave this option set to
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.

1-10 Fiery X3e Color Management
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 X3e.
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.
