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.
Separations
This option affects output only, allowing you to print all colors or
separate plates.

Description (PPD) file for a printer that supports color
separations.
Printer Halftone
