ES3640e MFP Color Reference Guide - 14
To create successful color documents and presentations, you can
take advantage of the features of color management software as
they are implemented by the Fiery 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
of the printer. This information is provided through
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 as 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 Fiery color management
system,
, supports this standard profile format.
