G-4 Glossary
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.
gamut
A range of colors. A device gamut is the
range of colors that a device, such as a
device, can produce. An image gamut is
the range of colors in a particular image.
gamut mapping
The conversion of color coordinates
from one device's gamut to another—
usually accomplished with algorithms or
look-up tables.
GCR
See Gray component replacement.
GDI (Graphics Device Interface)
Graphics and display technology used by
computers running Windows. GDI
applications rely on GDI (rather than
the PostScript language) to send text and
pictures to devices.
GIF (Graphics Interchange Format)
A standard developed by CompuServe
for bitmap graphics of up to 256 colors
and used for posting photographic
images on the Internet or intranet pages;
rarely used for professional printing.
gradient
A smooth transition between two
different colors or two shades of a color.
Graphics Device Interface
See GDI.
Graphics Interchange Format
See GIF.
gravure
A printing technology that uses an
etched cylinder that has been immersed
in ink. The ink that remains in the
etched areas is applied to the paper.
The non-etched surfaces of the cylinder
are non-printing areas.
gray component replacement (GCR)
A method for improving wet ink
trapping and reducing ink costs in
process color printing. In shadow,
midtone, and quarter-tone areas where
all three process colors (C, M, Y)
overprint, the gray components of those
colors are reduced and replaced by black.
