Co-op Color

General reference

The ICC standard is built upon the idea of the PCS (Profile Connection Space) reference media. ICC profiles therefore contain data that transforms device colors to the PCS, and from the PCS to device space.

While this system has been widely accepted throughout the printing industry, it isn't immune to criticism. The definition of the PCS is sometimes categorized as too narrow, because it does not define such aspects of the reference space as blackpoint and flare.
