Color Control
OKI Color Matching
This is OKI's proprietary color matching system and affects RGB
data only. This is the default setting and provides the fastest, best
color matching for your printer.
Postscript Color Matching
This uses PostScript Color Rendering Dictionaries built-in to the
printer, and affects both RGB and CMYK data.
No Color Matching
No color correction occurs when selected. This option is beneficial
when other matching regimens are used, specifically if you select a
Color Simulation option.
Print In Grayscale
No color will print. The printer will interpret all colors as a variation of
grays.
