There are four predefined renderings: Relative Colormetric, Perceptual, Saturation, and
Absolute Colormetric. You would probably select Relative Colormetric or Perceptual for
image or picture intensive files. Saturation would be most appropriate for documents
with a lot of business graphics (bar and pie charts). Even though Absolute Colormetric
often truncates out of gamut colors, it might be most appropriate for situations where
you must reproduce a color exactly, such as a shirt color in a catalogue or the logo color
for an important client.
Within the RIP, each of these Color Rendering Intents has the effect of mapping all the
ICC color data (LAB, CalRGB, CalGray) through a PostScript Color Rendering Dictionary
(CRD). In theory, there should be a different CRD for each rendering intent. But in some
devices, more than one Color Rendering Intent may be mapped into a single CRD.
