4. Under Color Mode, use the Color Control drop-down list to
select one of the following Color Control Methods:
a. OKI Color Matching
This is OKI’s proprietary color matching system, and affects
RGB data only. See “OKI Color Matching” on page 329.
b. PostScript Color Matching
This uses PostScript Color Rendering Dictionaries built into
the printer, and affects both RGB and CMYK data. See
“PostScript Color Matching” on page 331.
c. Using ICC Profiles
This option provides a method of matching RGB colors similar
to Windows ICM matching. See “Using ICC Profiles” on
page 333.
d. Windows ICM
This is the color management system built into Windows.
See “Windows ICM Color Matching” on page 335.
e. No Color Matching
Use this option to switch off all printer 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.
f. Print in Grayscale
This option prints all documents as monochrome. No color
prints. The printer interprets all colors as a variation of grays.
