Relative colorimetric
“Relative Colorimetric” is one of four rendering intents in gamut mapping.
Lexicon
Rendering intent
In gamut mapping, the rendering intent (rendering priority) is the strategy by which colours are converted from one colour space to another.
There are four types of rendering intents, defined by ICC: Perceprtual, Saturation, Absolute Colorimetric and Relative Colorimetric.
RGB
RGB stands for red, green and blue. Human colour vision is based on these colours.
RIP
A RIP is a raster image processor. A RIP is normally understood as a software, sometimes also a hardware or a software / hardware combination, that converts Postscript or PDF data of a page description language into raster points or image files that a “imagesetter” can expose to a plate, film or a proof output.
