This is a powerful colour management system based on
ICC colour profiles.
Profiles can be down loaded to the printer hard disk using
a special utility, and then colour matching can be applied
to all incoming print jobs.
The Graphic Pro colour management system is
recommended for users who are already familiar with ICC
profile-based colour matching and require more control
over colour.

COLOUR
Some application programs give you the choice to create and edit
documents using either RGB colour or CMYK colour. Typically,
only professional graphics and desktop publishing software
support CMYK colour. Most application programs only support
RGB colour, for example Microsoft Office programs or web
browsers.
If your application program does not give you the choice of RGB
or CMYK colour, you should assume that it only supports RGB.
The RGB colour model is based on the three primary colours of
light;
Red , Green and Blue . This model is used by scanners,
digital cameras and computer monitors.
The CMYK colour model is based on Cyan , Magenta , Yellow and
Black printer inks or toners.
