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:
• A Color Matching Processor
• A Device-Independent color space, frequently called a Reference Color Space or Profile Con-
nection Space (PCS), which acts as a Rosette Stone in the translation 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.
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 “destination” device.
