A BOUT RGB AND CMYK COLOR
Some application programs give you the choice to create and edit
documents using either RGB color or CMYK color. Typically, only
professional graphics and desktop publishing software support
CMYK color. Most application programs only support RGB color,
for example Microsoft Office programs or web browsers.
If your application program does not give you the choice of RGB
or CMYK color, you should assume that it only supports RGB.
The RGB color model is based on the three primary colors of light;
Red, Green and Blue. This model is used by scanners, digital
cameras and computer monitors.
The CMYK color model is based on Cyan, Magenta, Yellow and
Black printer inks or toners.
A BOUT THE PRINTER DRIVERS
Depending on your operating system, you may have the choice
of different drivers to use with your MFP. You may wish to select
a printer driver based on whether it supports CMYK data.
