白马过隙...

Keep in mind the following phrase:

Clean and bright is always right;
Dull and gray is not the way.
A pretty sight that will delight,
The client will pay without delay.

What is CMS? What can it do?

An ICC Profile is a piece of data that defines the color and reproduction characteristics of a device. ICC Profiles are written in a standard data format thant is OS independent.

Everybody can read and write ICC profiles if they know the data format.

In order to represent a color on a device, we need to know the color’s coordinates for the device. This is done by the Color Management System. The CMS is capable of translating colors specified in a device dependent coordinate into the coordinates for another device, thus matching colors between an original image, scanner, monitor, printer…ColorSync is the built-in CMS for Apple computers and is also used by some third party vendors. Colorsync ‘links together’ ICC-profiles to get a translation from one device to anoter. Another important CMS is Image Color Matching (ICM) for a Windows platform.
