11 About this manual
C9800 Color Guide - 11
This manual explains how to manage color output on the Fiery, and provides
information on calibration and color profiles.
This manual is part of a set of documentation that includes manuals for users and
system administrators. The other manuals are available at your site—refer to them for
a complete description of your Fiery.
NOTE:The term “Fiery” is used in this manual to refer to the Fiery Network Controller
for C9800. The name “Aero” is used in illustrations to represent the Fiery. The term
“Windows” is used to refer to Windows 98, Windows Me, Windows NT 4.0,
Windows 2000, Windows XP, and Windows Server 2003, wherever appropriate.
Illustrations of Windows software may not necessarily reflect the version of Windows
that you use.
About this manual
This manual is organized to supply you with key information about managing the
color output of your Fiery.
•Chapter 1 describes the Fiery print options and how to get the best color results.
•Chapter 2 covers various methods of calibrating the Fiery.
•Chapter 3 discusses the features of ColorWise Pro Tools. ColorWise Pro Tools
include Profile Manager, used to manage color profiles on the Fiery, and Color
Editor, which allows you to customize simulation and output profiles. This chapter
also describes Spot-On®, which allows you to define CMYK equivalents for spot
colors. Spot-On®is a utility supplied with C9800 GA only. It is not available for
standard models.
•Appendix A provides information about setting up and calibrating color
measurement instruments.
•Appendix B describes the Simple ASCII File Format (SAIFF), which can be used to
import toner density measurements from measurement devices.
Introduction

12 Introduction
C9800 Color Guide - 12
•TheFiery Color Reference Glossary defines words in bold—for example, output
profile—that appear throughout this manual. Color terms and concepts, such as
“color space,” “spot color,” “gamut,” and “source profile,” are used throughout this
manual. If you are new to desktop color, or if any terms are unfamiliar, check the
Glossary.
Key features of ColorWise
ColorWise is the color management system (CMS) built into the Fiery and designed to
provide both casual and expert users with the best color output for a variety of
purposes. The ColorWise default settings provide high-quality out-of-box color from
many Windows and Mac OS applications. This allows casual users to achieve quality
output without knowing about or changing any color settings on the Fiery.
For consistent color, calibrate the Fiery on a regular basis. ColorWise Pro Tools include
an easy-to-use calibrator, which allows you to calibrate using a spectrophotometer or
densitometer (see Chapter 2).
ColorWise features allow you to modify printing results. Depending on your particular
needs, you can:
• Set the behavior of CMYK printing to emulate DIC, Euroscale, and SWOP offset
press standards.
• Match PANTONE and other spot colors for the best match when printed using
four-color press conditions or when printed using presses with extra, custom plates.
• Select a color rendering dictionary (CRD), also called a rendering style, for RGB
printing. CRDs allow for rich, saturated printing of presentation graphics; smooth,
accurate printing of photographs; and relative or absolute colorimetric rendering for
specialized needs.

13 Key features of ColorWise
C9800 Color Guide - 13
• Define the source of incoming RGB color data for better screen matching and
provide for better color conversion of RGB data with no source information.
• Define whether RGB data is converted into the full gamut of the printer or whether
it is first converted into the gamut of another device, such as a press standard. This
feature is helpful for making one device behave like another. It is also useful for
evaluating the appearance of the RGB file under different printing conditions
without having to reprocess the RGB data each time.
ColorWise color management (ColorWise) offers an open color architecture, allowing
users to customize the Fiery to meet new printing needs as they arise. ColorWise
supports ICC profiles, which are industry standard color profiles that describe the
color behavior of a device. Downloading ICC profiles to the Fiery enables the Fiery to
simulate a custom press (or another printer), as well as accurately print colors from a
particular monitor or a scanner. In addition, you can create customized ICC profiles
for the printer.
ColorWise also allows you to use any Status T densitometer by importing data in a
standard file format (see Appendix B). In this case, it is important to note that the
quality of the instrument used will determine the quality of the calibration.

1-14 Managing color on the Fiery
C9800 Color Guide - 14
The following sections describe the options available from the ColorWise color
management system and explain how to customize the color settings for your
particular needs. They provide descriptions of the preset ColorWise default settings
and cover additional options for users who need to customize ColorWise.
For information on PostScript Level 2 or 3 printer drivers, see page 1-27. The section
also contains information on the capabilities of printer drivers and instructions for
setting color options with the PostScript drivers for Windows and Mac OS computers.
Managing color on the Fiery
To modify printing behavior, do any of the following:
• Select ColorWise options for an individual print job using menus that appear in the
printer driver.
• Select most ColorWise options as server defaults from the “Color Setup” application
in ColorWise Pro Tools (see page 3-83). Defaults can also be set from Fiery Setup, as
described in the Configuration Guide Chapter 4. These defaults will apply to all
subsequent print jobs unless you override them.
• Select some ColorWise options, particularly default ICC profile settings and
calibration options, from ColorWise Pro Tools. These options include default
Simulation Profile (see page 1-23), CMYK Simulation Method (see page 1-24),
Appear in Driver as (see page 3-61), default Source Profile (see page 1-22), RGB
Separation (see page 1-25), and associated calibration set (see page 2-36).
Applications can generate color data for the Fiery in many different color spaces. The
most common type of color data produced from office applications is RGB, while
prepress applications generally produce CMYK data. Desktop applications can also
generate spot colors, such as PANTONE colors. To complicate matters, a single page
may contain a mix of RGB, CMYK, and spot colors. The Fiery allows users to control
the printing of these mixed-color documents with features that apply specifically to
RGB, CMYK, or spot color data. Fiery color management generates CMYK data to be
sent to the printer.

C9800 Color Guide - 15
The following diagram illustrates the print options in the Fiery color management
process that affect color data conversions. You can 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.
NOTE: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.

You can specify settings for the following options by selecting 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 using print options over-
ride the defaults. Some options are only available with Spot-On, which is supplied
with C9800 GA only.
Fiery 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.
CMYK Simulation Method
Quick/Full (Source GCR)/Full (Output
GCR)
(Default set at Setup or with ColorWise Pro
Tools)
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 1-24).
CMYK Simulation Profile
SWOP-Coated (EFI)/DIC (EFI)/
Euroscale (EFI)/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. Choosing None bypasses simulation (see
page 1-23).
Color Mode (Mac OS)
CMYK/Grayscale
or
Print Mode (Windows)
Standard Color/Expert Color/Grayscale
Specifies the output color space of the job. Select CMYK, Standard Color, or
Expert Color for a full-color document.
(Other) Gamma
1.0/1.2/1.4/1.6/1.8/2.0/2.2/2.4/2.6/2.8/3.0
(Default set with ColorWise Pro Tools)
Applies the specified gamma value to the RGB source space definition (see
page 1-22). To use this print option, you must choose Other as the RGB
Source Profile setting.
(Other) White Point
5000 K (D50)/5500 K/6500 K (D65)/
7500 K/9300 K
(Default set with ColorWise Pro Tools)
Applies the specified white point value to the RGB source color space
definition (see page 1-22). To use this print option, you must choose Other as
the RGB Source Profile setting.
(Other) Phosphors
Hitachi EBU/Hitachi-Ikegami/NTSC/
Radius Pivot/SMPTE/Trinitron
(Default set with ColorWise Pro Tools)
Applies the specified phosphor (monitor type) information to the RGB source
space definition (see page 1-22). To use this print option, you must choose
Other as the RGB Source Profile setting.

C9800 Color Guide - 17
Detailed explanations of how these and other settings affect your print jobs are
provided in subsequent sections of this chapter.
Output Profile
Output1-10
(Default set at Setup or with ColorWise Pro
Tools)
The output profile is applied to all data in the print job (see page 1-26). User-
defined output profiles can be downloaded to the Fiery using ColorWise Pro
Tools. For more information about using ColorWise Pro Tools, see Chapter 3.
Pure Black Text/Graphics
On/Off
(Default set at Setup or with ColorWise Pro
Tools)
The On setting optimizes the quality of black text and line art output (see
page 1-19).
Rendering Style
Photographic/Presentation/Relative
Colorimetric/Absolute Colorimetric
(Default set at Setup or with ColorWise Pro
Tools)
Applies a Fiery color rendering dictionary (CRD) to RGB data (see page 1-18),
or to any incoming data with a PostScript source color space definition,
including CMYK.
RGB Separation
Output/Simulation
(Default set at Setup or with ColorWise Pro
Tools)
Determines which CMYK color space your original RGB data will be
separated into—CMYK for the printer (Output) or CMYK for a specified
simulation (Simulation). For more information, see page 1-25.
NOTE:When RGB Separation is set to Simulation, RGB colors are affected by
CMYK Simulation Profile and CMYK Simulation Method.
RGB Source Profile
EFIRGB/sRGB (PC)
/Apple Standard/Other/
None
(Default set at Setup or with ColorWise Pro
Tools)
Applies an RGB source space definition to RGB data (see page 1-22). If you
choose the Other setting, you must also specify particular settings for Gamma,
Phosphors, and White Point. See the corresponding options in this table. This
option, along with Gamma, Phosphors, and White Point, only affects
DeviceRGB or calibrated RGB color spaces.
Spot Color Matching
On/Off
(Default set at Setup or with ColorWise Pro
Tools)
The On setting enables Fiery-defined matching of spot colors to their best
CMYK equivalents. With Spot-On, you can manage and edit these spot color
matches (see page 3-70). Off instructs the Fiery to match color output to a
CMYK combination specified by the source application for the document (see
page 1-21).

Rendering Style
The Rendering Style option specifies a CRD for color conversions. To control the
appearance of images, such as prints from office applications or RGB photographs
from Photoshop, select the appropriate Rendering Style. The Fiery allows you to select
from the four rendering styles currently found in industry standard ICC profiles.
Fiery rendering style Best used for Equivalent ICC
rendering style
Photographic—Typically results
in less saturated output than
presentation rendering when
printing out-of-gamut colors. It
preserves tonal relationships in
images.
Photographs, including scans
and images from stock
photography CDs and digital
camera images.
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 color
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.
Relative Colorimetric
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.

Pure Black Text/Graphics
The Pure Black Text/Graphics option affects the printout for black text and vector
graphics on a page. Under most circumstances, leave this option set to On. When Pure
Black Text/Graphics is on, black colors generated by applications (for example, RGB =
0, 0, 0; CMYK = 0%, 0%, 0%, 100%; or K = 100%) are printed using the maximum
amount of black toner allowed by the calibration curve. This means the black text and
line art will not exhibit halftone artifacts (as long as the printer is calibrated correctly)
and will not be misregistered, since there is only one toner used. In addition, this
setting eliminates blasting.
For some jobs, it is preferable to clear this option, for example, if the page includes
gradient fills that use black. The following table describes the behavior of the Pure
Black Text/Graphics option with black data defined in different color spaces.
NOTE:Use the Pure Black Text/Graphics option 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. These
elements are not affected by the Pure Black Text/Graphics option. For details, see the
application notes. Also, black text and line art defined as RGB = 0, 0, 0 in office
applications (such as Microsoft Word) are converted to single-color black (CMYK =
0%, 0%, 0%, 100%) by the Microsoft PostScript Level 3 driver for Windows
2000/XP. To print this single-color black at the maximum toner density of the printer,
set the Pure Black Text/Graphics option to On.

CMYK Prints only with black toner, because CMYK
simulations preserve the black channel. The actual
amount of toner used depends on the current
simulation and the calibration state of the printer.
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 printer.

Black Overprint
The Black Overprint option allows you to specify whether or not black text or
text/graphics—defined as RGB = 0, 0, 0, or as CMYK = 0%, 0%, 0%, 100%—
overprints colored backgrounds.
•Text—Black text overprints colored backgrounds, eliminating white gaps and
reducing halo effects or misregistration of colors.
•Text & Graphics—Black text and graphics overprint colored backgrounds,
eliminating white gaps and reducing halo effects or misregistration of colors.
•Off—Black text or text/graphics knocks out colored backgrounds.
NOTE:PostScript applications may perform their own black overprint conversions
before sending the print job to the Fiery.
One example of how you might use this setting is with a page that contains black text
on a light blue background. The background blue color is CMYK = 40%, 30%, 0%,
0% and the black text is CMYK = 0%, 0%, 0%, 100%.
• With Black Overprint set to Text or Text & Graphics, the final text or text/graphic
portions of the page are overprinted, or combined with the underlying colors. Black
colors generated by applications (for example, RGB = 0%, 0%, 0%; CMYK = 0%,
0%, 0%, 100%) are printed using the maximum amount of black toner allowed by
the calibration curve. This means that black text and line art will not exhibit
halftone artifacts (as long as the printer is calibrated correctly). There is no transition
in the cyan and magenta toners, and the quality of the output is improved since it
will not show artifacts near the edges of the text or text/graphics. The option also
works with text defined in the RGB color space, that is RGB = 0, 0, 0.
• With Black Overprint Off, the border of the text or text/graphics is on an edge that
has cyan and magenta toners on one side (outside the text) and black toner on the
other side (inside the text). This transition may cause visible artifacts because of the
practical limitations of the printer.
