Color Reference Guide for C9800 - 98
CMYK
A subtractive color model that uses cyan,
magenta, yellow, and black, or process
colors, used in color printing; a color
model used in the printing of colors in
four-color process printing.
color channel
A single-color image that can be edited
separately from the other color channels
comprising a color space—for example,
the red channel of an RGB image.
color gamut
See
color management system (CMS)
System used to match color across
different input, display, and output
devices.
color rendering dictionary
See
(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 printers,
respectively. Other color spaces, such as
CIE Lab, are based on mathematical
models and are device-independent (that
is, not based on the color response of a
particular device).
See
colorant
An ink, dye, toner, paint, or other
pigment that modifies the color of media
to which it is applied.
ColorWise

ColorWise color management
An 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.
