Rendering Intents
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.
The printer driver provides the rendering intents listed below:
–Auto
Best choice for printing general documents.
–Perceptual
Best choice for printing photographs. Compresses the
source gamut into the printer's gamut while maintaining
the overall appearance of an image. This option attempts
to simulate RGB color.
– 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.
Unlike Absolute Colorimetric, Relative Colorimetric
attempts to take the paper white into account.
– Absolute Colorimetric
Best for printing solid colors and tints (such as Company
logos). Matches colors common to both devices exactly.
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.
