“Absolute colorimetric” (also known as colorimetric) is one of four rendering intents in gamut mapping.
When converting from a larger colour space to a smaller colour space, all displayable colours, including the white point, of the original colour space are directly transferred to the destination colour space.
Any colours that lie outside the destination colour space are positioned at its edge (Clipping).
This method is particularly suitable for the most accurate colour reproduction of spot colours with CMYK or for digital proofs, as long as the colour spaces are of similar size.
