About this document
This document is organized to supply you with key information about managing the color
output of your CX3641MFP.
This document covers the following topics:
• Installing and configuring ColorWise Pro Tools
• Using Color Editor, Profile Manager, and Color Setup
• Overview of calibration and description of how to calibrate the CX3641MFP using
various ColorWise Pro Tools Calibrator methods
• Using Spot-On to manage spot colors
• Setting ColorWise print options from Windows and Mac OS computers
• Descriptions of Simple ASCII File Format (SAIFF), which can be used to import toner
density measurements from measurement devices
NOTE: The Glossary defines words in bold, for example, output profile, that appear
throughout this document. Color terms and concepts, such as “color space,” “spot color,”
“gamut,” and “source profile,” are used throughout this document. If you are new to
desktop color, or if any terms are unfamiliar, see the Glossary.
Key features of ColorWise
ColorWise is the color management system (CMS) built into the CX3641MFP 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 CX3641MFP.
For consistent color, calibrate the CX3641MFP on a regular basis. ColorWise Pro Tools
includes an easy-to-use calibrator, which allows you to calibrate using either the scanning
unit that is part of the copier/printer or an optional spectrophotometer or densitometer
(see “Calibration” on page 33).
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, SWOP, and other
offset press standards.
• Match PANTONE and other spot colors for the best match when printing using
four-color press conditions or presses with extra, custom plates.

INTRODUCTION 9
• 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 color conversion of RGB data
with no source information.
• Determine whether RGB data is converted into the full gamut of the copier/printer or is
first converted into the gamut of another device, such as a press standard. This feature
is useful for making one device behave like another for RGB data. It also allows you to
evaluate the appearance of an RGB file under different printing conditions without
having to convert the RGB file to CMYK first.
ColorWise color management (ColorWise) offers an open color architecture, allowing
users to customize the CX3641MFP 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. Note that ICC specification version 4 profiles (profile version
4.2.0.0) are supported as well as version 2. Downloading ICC profiles to the CX3641MFP
enables the CX3641MFP to simulate a custom press (or another copier/printer), as well as
accurately print colors from a particular monitor or scanner. In addition, you can create
customized ICC profiles for the copier/printer.
ColorWise also allows you to use any Status T densitometer by importing data in a
standard file format (see “Importing Density Measurements” on page 101). In this case, it
is important to note that the quality of the instrument used determines the quality of the
calibration.

COLORWISE PRO TOOLS
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 color settings on the CX3641MFP. The ColorWise
color management system (CMS) also allows expert users to obtain the best color output.
ColorWise Pro Tools allows users to customize settings to achieve the best output for a
variety of purposes.
Designed to give flexible control of color printing, ColorWise Pro Tools includes the
following color management tools:
• Calibrator (calibrate the CX3641MFP in various ways)
• Color Editor (customize simulation and output profiles)
• Profile Manager (manage profiles)
• Spot-On (define CMYK equivalents for spot colors)
Spot-On is offered as an option.
• Color Setup (set defaults for ColorWise print options)

COLORWISE PRO TOOLS 20
Using ColorWise Pro Tools
ColorWise Pro Tools gives you flexible control of color printing by allowing you to
calibrate the CX3641MFP, customize simulation and output profiles, manage profiles on
the CX3641MFP, manage spot colors, and set default values for ColorWise print options.
Using Calibrator
ColorWise Pro Tools Calibrator allows you to calibrate the CX3641MFP using one of a
number of measurement methods. For information about calibrating the CX3641MFP, see
page 33.
Using Color Editor
ColorWise Pro Tools Color Editor allows you to create custom profiles by editing existing
simulation or output profiles, and then saving the changes as a new profile. Use Color
Editor to fine-tune a profile on the CX3641MFP to meet your exact specifications. Access
Color Editor directly, by clicking its icon in the ColorWise Pro Tools main window, or
indirectly, through the Profile Manager.
NOTE: You cannot edit source profiles. Only simulation and output profiles can be
customized.
TOUSE COLOR EDITOR
1 Start ColorWise Pro Tools and connect to the CX3641MFP.
