G-2 Glossary
color management system (CMS)
System used to match color across
different input, display, and output
devices.
color rendering dictionary
See CRD (color rendering dictionary).
color separation
The process of separating a color
image into the color components for
printing—cyan, magenta, yellow, and
black. Also used to refer to the four
sheets of film that result from the process
of separating a color image.
color space
A model for representing color in terms
of measurable values, such as the amount
of red, green, and blue in an image. RGB
and CMYK color spaces correspond to
color devices—monitors and copier/
printers respectively. Other color spaces,
such as CIE Lab, are based on
mathematical models and are device-
independent. They are not based on the
color response of a particular device. See
gamut.
colorant
An ink, dye, toner, paint, or other
pigment that modifies the color of media
to which it is applied.
ColorWise
See ColorWise color management.
ColorWise color management
Fiery ICC-open color management
solution, which is an easy-to-use system
that addresses the needs of both casual
and experienced color management
users.
composite printer
Any output device that can print directly
in color without first creating color
separations. A composite print can be
used as an early proof of an offset print
job.
continuous tone (contone)
Describes a photographic image that
contains gradient tones from black to
white (such as a 35mm transparency or a
photograph). Continuous tones cannot
be reproduced in that form for printing,
but must be screened to translate the
image into dots.
continuous tone (contone) image
An image containing fine gradations of
tones, such as a photographic image.
CRD (Color Rendering Dictionary)
A feature of color management systems
and PostScript Level 2 and PostScript 3
color copier/printers that maintains the
best possible translation of color from
one color device to another. A color
rendering dictionary (CRD) is used by
the color management system or the
copier/printer's PostScript interpreter
when converting data between color
spaces. The Fiery includes several CRDs,
each of which provides a different color
rendering style.
