Glossary
pixel
The smallest distinct element of a raster
image or an image displayed on a
monitor. The term is a combination of
the words “picture” and “element.”
PostScript
Adobe Systems’ computer language for
defining text and pictures. The current
version is PostScript 3. PostScript Level 2
included many enhancements to
PostScript Level 1 including improved
color matching and the ability to control
printer-specific features from
applications. EPS (Encapsulated
PostScript) images are PostScript files.
PostScript Printer Description file
(PPD)
A file containing information about a
particular PostScript print device’s
capabilities and restrictions. The
information in the PPD is presented to
you via the printer driver.
prepress proof
A print made from a set of film
separations, or from an electronic file, to
simulate the results of printing. A film
proof is the last opportunity to catch
problems before the final printing.
presentation graphics rendering
A color rendering style that does not try
to precisely match printed colors to
displayed colors. It is appropriate for
bright saturated colors used in
illustrations and graphs.
process colors

A digital file that describes the color
capabilities, including the gamut, of a
color device.
QuickDraw
Graphics and display technology built

applications rely on QuickDraw (rather
than the PostScript language) to send
words and pictures to printers.
raster image
Electronic representation of a page or
image using a grid of points called pixels.
rendering intent
A 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.
resolution
The number of pixels per inch in a
bitmap image or the number of dots per
inch that an output device can print.
solid color rendering
A color rendering style intended for use
when color accuracy is crucial.
Unprintable colors are mapped to the
