What is an input profile / standardization?

Definition
An input profile / standardisation defines what colour space you must use to interpret
the colour information of the file you want to print in a correct manner.
The two main input profiles (colour spaces) are the following.
• RGB
The RGB colour space is based on the RGB colour model. RGB (Red, Green, Blue)
is a suitable colour model for computer graphics because the human visual system
operates in a similar manner.
The RGB colour space is an additive colour space, where you can mix colours based
on light. You can create white light if you add equal parts of each of the three primary
colours: Red, green and blue All three colours are required to produce white and the
absence of all three produces black. In additive mixing, the RGB colours are the pri-
mary colours and cyan, magenta, and yellow (CMY) are the secondary colours.
• CMYK (Colours you print)
The CMYK colour space is based on the CMYK colour model. The CMYK (Cyan,
Magenta, Yellow and Black colour space is a subtractive colour space, where you can
mix colours based on subtracting light energy from the spectrum. The CMY toners
are used to create RGB colours. All three inks are required to produce black and the
absence of all three produces white. In subtractive colour mixing the CMY colours
are the primary colours and RGB are the secondary colours.
