This manual introduces the concepts and issues associated with printing to the
Color Server ™ . It outlines key workflow scenarios and provides application notes that
explain how to print to the Color Server from popular Microsoft Windows and
Apple Mac OS applications. This reference guide also provides basic background
information on color theory and color management.
The Glossary at the back of this manual defines terms and concepts—for example,
output profile—that appear throughout this manual. Color terms and concepts such
as "RGB data," "color space," "spot color," "gamut," and "source profile" are used

Basics of color management

The past several years have seen progress toward standardization in the field of digital
color management systems. Both the Windows and Mac OS operating systems now
support an industry standard format developed by the International Color
Consortium (ICC). This ICC format is implemented on Windows computers in
Image Color Matching (ICM) and on Mac OS computers in ColorSync. More and
more software developers are also incorporating color management systems into
high-end applications. The Color Server color management system,
supports this standard profile format.
A color management system (CMS)
the source image (for example, the monitor or a scanner) and the color space of the
printer. The CMS uses a device-independent color space, such as CIELAB, as its
intermediate color space. To perform its translation, the CMS needs information about
the color space of the source image and the gamut of the printer. This information is
provided in the form of profiles, often created by the makers of the computer monitor
or printer. The end product of a CMS conversion is a printed document or an image
file in the gamut of a particular printer.
