How Color Management Works; How Cms Translates Between Devices - Microtek ArtixScan 120tf Reference Manual

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 Connection 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.
