Using ColorWise and application color management
The Color Server color management system,
ColorWise
is designed to provide both casual
and expert users the best color output for a variety of purposes. Several applications also
provide their own color management system. This manual describes how to optimize print
output using both ColorWise color management and application color management.

output using both ColorWise color management and application color management.
The Color Server can intelligently manage the printed appearance of
RGB
,
CMYK
, and
spot
colors
. You can allow the Color Server to manage color for most color printing jobs without
adjusting any settings.
A desktop (host-based) color management system uses
ICC profiles
to convert colors from
one device gamut to another (see
“Desktop Color Primer”
on page 73). The color data is
converted when it passes from one application to another or when the job is sent to the
printer; thus, the processing occurs on your computer, as opposed to the Color Server.

Conventional color management systems typically address only color conversions, and they
occupy your computer processor. When you use ColorWise, jobs leave your computer and are
processed faster on the Color Server.

The advantages to ColorWise color management versus desktop (application) color
management include the following:
management include the following:
• Relieving your computer from performing additional processing. Delaying color
conversions until the color data reaches the Color Server frees your computer so that you
can continue working, and color conversions on the Color Server are, in most cases, much
faster than similar conversions on a host computer.

• Eliminating the potential for undesirable color management-related conflicts, such as
iterative color conversions and inconsistent color. The Color Server applies global
corrections to specific groups of RGB, CMYK, and spot colors to avoid such conflicts.
corrections to specific groups of RGB, CMYK, and spot colors to avoid such conflicts.
• Accepting RGB files in addition to larger CMYK files from applications, which minimizes
network traffic and enables jobs to print faster.
ColorWise uses ICC profiles to convert colors to the device gamut or simulate other devices,
such as an offset printing press. ColorWise manages color conversions for all users printing to
the Color Server from Windows and Mac OS computers. It allows users to follow a simple
workflow with minimal intervention using robust default settings, while giving advanced
users the control and precision they need.
