How Color Management Works
The aim of color management is to preserve true color information by making up
for the differences in the way devices communicate color. Your CMS does this by
using a scientifically designed system including:
for the differences in the way devices communicate color. Your CMS does this by
using a scientifically designed system including:
• A Color Matching Processor
• A Device-Independent color space, frequently called a Reference Color Space
or Profile Connection Space (PCS), which acts as a Rosette Stone in the transla-
tion process
tion process
• Device Color Profiles (DCPs)
DCPs relate a device dependent color space to the Profile Connection Space.
The CMS uses the Color Profile to translate from one device dependent color
space to another.
space to another.
How CMS Translates between Devices
When you scan an image, a CMS uses the information about the scanner—stored
in the Scanner Color Profile—to translate the RGB image from the scanner to the
Profile Connection Space. The CMS then uses the information about your
monitor—stored in the Monitor Color Profile—to translate the image from the
Profile Connection Space to your monitor color space, where you see it displayed.

In this example, the scanner is the “source” device, and the monitor is the
