Rendering intents - PCL5c driver only
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.
SETTING
Off
Perceptual
Saturation
Relative Colorimetric
Absolute
Colorimetric
To change these settings in your printer driver:
1. Click the Colour tab.
2. Select Manual Settings and click Options....
3. Select Printer Colour Matching and choose the desired rendering intent from the
drop-down list.
DESCRIPTION
Default setting.
Best choice for printing photographs.
Compresses the source gamut into the printer's gamut while
maintaining the overall appearance of an image. This may
change the overall appearance of an image as all the colours are
shifted together.
This option attempts to simulate RGB colour.
Best choice for printing bright and saturated colours if you don't
care how accurate the colours are.
Best choice for graphs, charts, diagrams etc.
Maps fully saturated colours in the source gamut to fully
saturated colours in the printer's gamut.
Good for proofing CMYK colour 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.
Best for printing solid colours and tints (such as Company logos).
Matches colours common to both devices (monitor and printer)
exactly. 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.
