Relative Colorimetric
Good for proofing CMYK colour images on a desktop printer.
Best for solid colours and tints.
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.
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.
5. Always use Printer Halftone
YOUR PRINTER
5
This option prevents the halftone of a high-end graphic
application from printing by using the printer's halftone
pattern instead of the application's one.
Click on the checkbox to enable the option.
