CRD (Color Rendering Dictionary)
A feature of color management systems
and PostScript Level 2 and PostScript 3
color devices 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
device’s PostScript interpreter when
converting data between color spaces.
The Fiery includes several CRDs, each of
which provides a different color
rendering style.
custom color system
A system of named color swatches that
can be matched on press using spot
colors or approximated using process
colors. PANTONE and TruMatch are
examples of custom color systems.
DCS (Desktop Color Separation)
A data file standard defined by Quark,
Inc., to assist in making color separations
with desktop publishing systems; five
files are created—four color files (one
each for C, M, Y, and K) and a
composite color preview file of the color
image. It allows an image-editing
application to perform color separation
and pass it through to final output with
its integrity intact.
densitometer
An instrument commonly used in the
graphic arts industry to measure density
according to a specified standard.
density
A measurement of the light-absorbing
quality of a photographic or printed
image.
desktop color separation
See DCS .
DIC
A Japanese standard of specifications for
separations, proofs, and color printing.
EPS (or EPSF)
See Encapsulated PostScript .
Encapsulated PostScript
A PostScript file format designed to be
embedded in another PostScript stream.
Euroscale
A European standard of specifications
for separations, proofs, and color
printing.
flexography
A printing technology that uses flexible
raised-image plates. Flexography can be
used to print on non-flat materials such
as cans.
four-color printer
A printing device that uses cyan,
magenta, yellow, and black ink or toner.
gamma
A numeric value representing the
relationship (gamma curve) between the
input and output values of a color
device. If gamma equals 1, input values
are mapped exactly to output values.
