PostScript
A device-independent page description
language developed by Adobe, which is
used to print and display pictures and
text. PostScript 3 includes many
enhancements to older versions of
PostScript, including improved image
quality and color with Enhanced Image
Technology, faster performance with
Advanced Page Processing, and ease of
use and setup with NetWorks System.

prepress proof
A print made from a set of film
separations or other file to simulate the
results of printing. A prepress proof is
the last opportunity to catch problems
before the print job goes to press.

presentation graphics rendering
A color rendering style that creates
saturated colors but does not match
printed colors precisely to displayed
colors. It is appropriate for bright
saturated colors used in illustrations
and graphs.

rendering intent
The style of color rendering, or gamut
mapping, designed for a particular type
of color job. An example of a rendering
intent is Photographic rendering—also
referred to as Image rendering or
Contrast rendering—which is designed
for photographic images.

An additive color model that makes a
range of colors by combining red, green,
and blue light, called the additive
primaries. Commonly used to refer to
the color space, mixing system, or
monitor in color computer graphics.
