ICC is the acronym of the International Color Consortium.

ICC profiles help you to get the correct color reproduction when you input images from a scanner or camera and display them on a monitor or print them. They define the relationship between the digital counts your device receives or transmits and a standard color space defined by ICC and based on a measurement system defined internationally by CIE. Thus, if you have a profile for each of your scanner, camera, display and printer, the fact that they refer to a standard color space lets you combine them so that you obtain the correct color as you get images from the scanner or camera and print or display them.

An ICC profile is one that conforms to the ICC specification. By conforming to this specification profiles may be exchanged and correctly interpreted by other users. The two main types of profiles are source (input) and destination (output) profiles and essentially consist of tables of data that relate the device co-ordinates to those of the standard color space defined by ICC. There are various relationships defined in each profile (known as rendering intents ? see a later question). Special types of profiles (devicelink, and abstract) are defined for special workflow applications.
