To create successful color documents and presentations, you can take advantage of the features
of color management software as they are implemented by the Color Server and on your
desktop computer. This chapter is devoted to various elements of color management that
contribute to predictable color results.

Understanding color management systems
A
color management system (CMS)
is a “translator” between the
color space
of the source
device (for example, the monitor or a scanner) and the color space of the destination device
(for example, the printer). It compares the color space in which the source image was created
to the color space in which the job will be output, and adjusts the colors in the document to
maintain consistency across different devices. A CMS typically uses a device-independent
color space, such as CIELAB, as its intermediate color space. To perform its translation, a
CMS needs information about the color space of the source image and the
(for example, the printer). It compares the color space in which the source image was created
to the color space in which the job will be output, and adjusts the colors in the document to
maintain consistency across different devices. A CMS typically uses a device-independent
color space, such as CIELAB, as its intermediate color space. To perform its translation, a
CMS needs information about the color space of the source image and the
gamut
of the
printer. This information is provided through
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.

There has been progress toward standardization in the field of digital color management
systems. Both the Windows and Mac OS operating systems support an industry standard
format developed by the International Color Consortium (ICC). This ICC format is
implemented on Windows computers and on Mac OS computers. Other software developers
are also incorporating color management systems into high-end applications.
