Introduction

xii Introduction
•TheFiery Colour Reference Glossary defines words in bold—for example, output
profile—that appear throughout this manual. Colour terms and concepts, such as
“colour space,” “spot colour,” “gamut,” and “source profile,” are used throughout
this manual. If you are new to desktop colour, or if any terms are unfamiliar, check
the Glossary.
Key features of ColorWise
ColorWise is the colour management system (CMS) built into the ES3640e MFP
and designed to provide both casual and expert users with the best colour output for a
variety of purposes. The ColorWise default settings provide high-quality out-of-box
colour from many Windows and Mac OS applications. This allows casual users to
achieve quality output without knowing about or changing any colour settings on the
ES3640e MFP.
For consistent colour, calibrate the ES3640e MFP on a regular basis. ColorWise Pro
Tools include an easy-to-use calibrator, which allows you to calibrate using either the
scanning unit that is part of the ES3640e MFP or 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 colours for the best match when printed using
four-colour press conditions or when printed using presses with extra, custom plates.
• Select a colour 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 colour data for better screen matching and
provide for better colour conversion of RGB data with no source information.

xiii Key features of ColorWise
• 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 colour management (ColorWise) offers an open colour architecture,
allowing users to customize the ES3640e MFP to meet new printing needs as they
arise. ColorWise supports ICC profiles, which are industry standard colour profiles
that describe the colour behavior of a device. Downloading ICC profiles to the
ES3640e MFP enables it to simulate a custom press (or another printer), as well as
accurately print colours from a particular monitor or a scanner. In addition, you can
create customized ICC profiles for the ES3640e MFP.
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
1-1 Managing colour on the ES3640e MFP
The following sections describe the options available from the ColorWise colour
management system and explain how to customize the colour 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 1-14. The section
also contains information on the capabilities of printer drivers and instructions for
setting colour options with the PostScript drivers for Windows and Mac OS
computers.
Managing colour on the ES3640e MFP
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 3-29). Defaults can also be set from 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 1-10), CMYK Simulation Method (see page 1-11),
Appear in Driver as (see page 3-7), default Source Profile (see page 1-9), RGB
Separation (see page 1-12), and associated calibration set (see page 2-4).
Applications can generate colour data for the ES3640e MFP in many different colour
spaces. The most common type of colour data produced from office applications is
RGB, while prepress applications generally produce CMYK data. Desktop applications
can also generate spot colours, such as PANTONE colours. To complicate matters, a
single page may contain a mix of RGB, CMYK, and spot colours. The ES3640e MFP
allows users to control the printing of these mixed-colour documents with features that
apply specifically to RGB, CMYK, or spot colour data. ES3640e MFP colour
management generates CMYK data to be sent to the printer.

1-2 Fiery Colour Management
The following diagram illustrates the print options in the ES3640e MFP colour
management process that affect colour data conversions. You can access these print
options when you send a print job to the ES3640e MFP. Most of these options and
settings are described in subsequent sections of this chapter.
RGB Source Profile is the only colour option that applies strictly to RGB colour data.
The other options that affect RGB colour also affect the more rarely used Lab, XYZ,
and other calibrated colour spaces.
N OTE : For users who are familiar with PostScript 3 colour, RGB Source Profile affects
all CIEBasedABC colour spaces (if the source space is RGB). If you send CMYK data
to the ES3640e MFP in CIEBasedDEFG format, for example, by choosing PostScript
Colour Management in Adobe Photoshop, the ES3640e MFP Rendering Style
selection—which normally affects only RGB data—will also affect this CMYK data.

1-3 Managing colour on the ES3640e MFP
You can specify settings for the following options by selecting print options when you
send a job to the ES3640e MFP. Some can also be set as defaults by the administrator
during Setup or using ColorWise Pro Tools. Settings specified using print options
override the defaults. .
Fiery colour print option What it does
Brightness
85% Lightest to 115% Darkest
Performs a colour adjustment on all colour 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 1-11).
CMYK Simulation Profile
SWOP-Coated (EFI)/DIC (EFI)/
Euroscale (EFI)/Match Copy/None
(Default set at Setup or in ColorWise Pro
Tools)
Adjusts CMYK colour data to simulate an offset press standard or a custom
colour gamut defined at your site. The Match Copy setting bypasses
calibration to match a copy made from the ES3640e MFP copier glass.
Choosing None bypasses simulation (see page 1-10).
Color Mode (Mac OS)
CMYK/Grayscale
or
Print Mode (Windows)
Standard Colour/Expert Colour/Grayscale
Specifies the output colour space of the job. Select CMYK, Standard Colour,
or Expert Colour for a full-colour 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 1-9). 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 colour space
definition (see page 1-9). 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 1-9). To use this print option, you must choose
Other as the RGB Source Profile setting.
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 1-13). User-
defined output profiles can be downloaded to the ES3640e MFP using
ColorWise Pro Tools. For more information about using ColorWise Pro Tools,
see Chapter 3.

1-4 Fiery Colour Management
Detailed explanations of how these and other settings affect your print jobs are
provided in subsequent sections of this chapter.
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 1-6).
Rendering Style
Photographic/Presentation/Relative
Colorimetric/Absolute Colorimetric
(Default set at Setup or with ColorWise Pro
Tools)
Applies a ES3640e MFP colour rendering dictionary
(CRD) to RGB data (see
page 1-5), or to any incoming data with a PostScript source colour space
definition, including CMYK.
RGB Separation
Output/Simulation
(Default set at Setup or with ColorWise Pro
Tools)
Determines which CMYK colour 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 1-12.
N
OTE :When RGB Separation is set to Simulation, RGB colours 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 1-9). 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 colour spaces.
Spot Colour Matching
On/Off
(Default set at Setup or with ColorWise Pro
Tools)
The On setting enables Fiery-defined matching of spot colours to their best
CMYK equivalents. With Spot-On, you can manage and edit these spot colour
matches (see page 3-16). Off instructs the ES3640e MFP to match colour
output to a CMYK combination specified by the source application for the
document (see page 1-8).

Rendering Style
The Rendering Style option specifies a CRD for colour conversions. To control the
appearance of images, such as prints from office applications or RGB photographs
from Photoshop, select the appropriate Rendering Style. The ES3640e MFP 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 colours.
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 colours but does not
match printed colours precisely
to displayed colours. In-gamut
colours 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 colour
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 colour
matching is important, but you
prefer white colours in the
document to print as paper
white. It may also be used with
PostScript colour 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 colours
are needed and visible borders
are not distracting. It may also
be used with PostScript colour
management to affect CMYK
data for simulation purposes.

1-6 Fiery Colour Management
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 colours 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 colour spaces.
N OTE : Use the Pure Black Text/Graphics option only when printing composites, not
when printing separations.
N OTE : PostScript applications (such as QuarkXPress) may convert elements defined as
RGB = 0, 0, 0 to four-colour CMYK black before sending the job to the
ES3640e MFP. 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-
colour black (CMYK = 0%, 0%, 0%, 100%) by the Microsoft PostScript Level 3
driver for Windows 2000/XP. To print this single-colour black at the maximum toner
density of the printer, set the Pure Black Text/Graphics option to On.

RGB Prints 100% black With the default profile, prints a rich black using
all toners.
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 colour
simulations preserve the black channel. The actual
amount of toner used depends on the current
simulation and the calibration state of the printer.
