Choosing a Color Matching Method

There is no one correct way to achieve a good color match between
the document displayed on your monitor, and it's printed equivalent.
There are many factors involved in achieving accurate and
reproducible color.
However, the following guidelines may help in achieving good color
output from your printer. There are several suggested methods,
depending on the type of document you are printing.

RGB or CMYK?

The guidlines for choosing a color matching method makes
distinctions between Red, Green, Blue (RGB) and Cyan, Magenta,
Yellow, Black (CMYK).
Generally, most office documents you print will be in RGB format.
This is the most common, and, if you do not know your document’s
color mode, assume that it is RGB.
Typically CMYK documents are only used in professional Desktop
Publishing and Graphics applications.

Oki’s Color Matching (found in the printer driver under Printer
Features Features 2) is a generally a good choice. Select a
matching method appropriate to your monitor.
NOTE
These suggestions are for guidance only. Your results may
vary depending on the application from which you are
printing. Some applications will override any color matching
settings in the printer driver without warning.
