Rendering Intent
When a document is printed, a conversion takes place from the
document's color space to the printer color space. The rendering
intents are essentially a set of rules that determine how this color
conversion takes place.
Auto
The best default select as this selects the optimal settings for a
general office environment.
Perceptual
Best choice for printing photographs. Compresses the source
gamut into the printer's gamut whilst maintaining the overall
appearance of an image. This may change the overall appearance
of an image as all the colors are shifted together.
Saturation
Best choice for printing bright and saturated colors if you don't
necessarily care how accurate the colors are. This makes it the
recommended choice for graphs, charts, diagrams, etc. Maps fully
saturated colors in the source gamut to fully saturated colors in the
printer's gamut.
Relative Colorimetric
Good for proofing CMYK color images on a desktop printer. Much
like Absolute Colorimetric, except that it scales the source white to
the (usually) paper white; i.e. unlike Absolute Colorimetric, this
attempts to take the paper white into account.
Absolute Colorimetric
Best for printing solid colors and tints, such as company logos etc.
Matches colors common to both devices exactly, and clips the out
of gamut colors to their nearest printed equivalent. Tries to print
white as it appears on screen. The white of a monitor is often very
different from paper white, so this may result in color casts,
especially in the lighter areas of an image.
