Select the drop down choice next to CHROMA to select the color type.
POSTSCRIPT
There are two levels; level 2 is the default setting, but level 1 should be selected when using an older model PS printer.
RUN LENGTH ENCODE and ASCII 85 ENCODE are used to reduce the postscript file size. Usually the reductions are significant. (For PS Level 1 these are automatically turned off.)
