Glossary
output profile
A file that describes the color
characteristics of a printing device.
The output profile is associated with
a calibration target that defines the
expected density response of the device.

phosphor
Material used in making computer
monitors; phosphors glow and emit red,
green, and blue light when struck by an
electron beam, thus creating an image.

photographic rendering
A color rendering style that preserves
tonal relationships in images.
Unprintable colors are mapped to
printable colors in a way that retains
differences in lightness, sacrificing color
accuracy as necessary.

image. The term is a combination of the
words “picture” and “element.”

used to print and display pictures and
text. PostScript 3 includes many
enhancements to older versions of
PostScript, including improved image
quality and color.

PPD (PostScript Printer Description
file)
file)
A file containing information about
a particular PostScript print device’s
capabilities and restrictions. The
information in the PPD is presented
via the printer driver.

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.

process colors
The colors used in printing to simulate
full-spectrum color images: Cyan,
Magenta, Yellow, blacK (CMYK).

profile
Systematically describes how a color
maps to a particular space. By
identifying a source profile and an
output profile, you initiate the
appropriate workflow to maintain
consistent color values.
