Color Management Guide
For CMYK images, using System Specified (default)
rendering is perfectly acceptable. The Saturation
intent for CMYK 4x4 LUT is derived from the Relative
Colorimetric intent.
In general, use Relative Colorimetric to match a proof.
Use the other rendering intents based upon
preference.

Use Saturation for rendering business graphics
such as Microsoft Power Point documents, charts,
graphs, etc.
Use Perceptual for rendering photographic
images to achieve a more press-like appearance.
Use Relative Colorimetric when attempting to
apply the closest color values in the print engine
color profile to the input profile, taking into
consideration the white point of the media. Used
for color matching such as matching a SWOP™
proof.
Use Absolute Colorimetric when attempting to
apply the closest color values in the print engine
color profile to the input profile using a standard
white point. Absolute Colorimetric is used for
comparing to an absolute value. Highlights tend to
be washed out and colors appear light using
Absolute Colorimetric rendering.
Use Pure for rendering text and line art, as it
subdues halftone textures to increase the visibility
of text on colored backgrounds. Pure works best
with RGB text.
