Colour management is a collection of rules and procedures in digital imagery which govern the control and management of every process involved in the colour transformations which occur during image capture or rendering images between input devices such as a digital camera or scanner or output devices such as our monitors or printers which render our images with ink on a substrate..
To boil it down, colour management is rather like a protocol for the translation of one language into another – say French into English with a person between having the ability to handle the translation between the two – except that instead of languages the subject of translation is a product of light. An example is an image captured by a digital camera which must be translated so that it can be shown by, i.e. output on a screen display or printed with ink on paper.
So, you might ask why is a translation necessary and what are we translating?
