Managing color
Color tools overview
The CX print server provides you with a number of tools and
options that enable you to adjust and improve the color quality in
your jobs.
The following tools are available:
Profile Manager
Spot Color Editor
Gradation Tool
Calibration table manager
Media and Color Manager
Managing color and profiles
A profile is a file that describes how a particular device reproduces
color. It represents the colorimetric behavior of a given device for
known media and imaging parameters (such as substrate/paper
stock, resolution, and inks). Profiles are used to reproduce color
from one device’s color space to another device's color space in a
consistent manner. They provide the necessary information to
convert color data between device-dependent color spaces and
device-independent color spaces. You use profiles to color manage
your system.
Color management is a series of steps taken to ensure that colors
are accurate and repeatable when transferred from one device to
another. Color management helps us reproduce the color
conceived by a graphic artist or photographer as closely as
possible on a monitor, a proof, or a press sheet. Color
management enables accurate and repeatable color reproduction,
within each device’s color capability, throughout the entire workflow.
Before you can print a color document, the color data in it must be
converted to the gamut of the printer. Whether performed by the
CX print server or a host-based CMS, the process of converting
color data for a printer is the same: the CMS interprets RGB object
data according to a specified source profile and adjusts both RGB
and CMYK data according to a specified output profile, also called
a destination profile by some color management systems.
