POSTSCRIPT COLOUR MATCHING
This uses PostScript Colour Rendering Dictionaries built into the
printer, and affects both RGB and CMYK data.

Rendering Intents
When a document is printed, a conversion takes place from the
document’s colour space to the printer colour space. The rendering
intents are essentially a set of rules that determine how this colour
conversion takes place.

conversion takes place.
The rendering intents that the printer driver provides are listed below:
>
Auto
The best default selection, 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 colours are shifted together.

Saturation
Best choice for printing bright and saturated colours if you
don’t necessarily care how accurate the colours are. This
makes it the recommended choice for graphs, charts, diagrams
etc. Maps fully saturated colours in the source gamut to fully
saturated colours in the printer’s gamut.

Absolute Colorimetric
Matches colours common to both devices exactly, and clips the
“out of gamut” colours 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 colour casts, especially in the lighter areas of an
image.
