4.Under Color Mode, use the 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 155.

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 157.

c.Using ICC Profiles

This option provides a method of matching RGB colors similar to Windows ICM matching. See “Using ICC Profiles” on page 159.

d.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.

e.Print in Grayscale

This option prints all documents as monochrome. No color prints. The printer interprets all colors as a variation of grays.
