four-color process
the use of four subtractive pigment-based primaries,
Yellow, Magenta Cyan, and blacK, to reproduce the
full spectrum in print. Can also be achieved with
three color process, Yellow, Magenta, and Cyan,
which are theoretically the compliment (opposite) to
the three additive primaries, Blue, Green, and Red.
exposure shift
a change in a lighter or darker direction.
GCR
gray component replacement is the use of black ink
to substitute for common quantities of colored inks.
In other words, when the print has a large gray area
that is being reproduced using approximately equal
quantities of cyan, magenta, and yellow ink, the
common component of the three colors can be
replaced with a similar density of black ink. Also
called ‘achromatic’ reproduction.
gray balance
the relative proportion of primary colors, additive or
subtractive, needed to produce a neutral tone from
dark to light intensities.
GPIB
General Purpose Interface Bus, sometimes called
HP-IB for Hewlett Packard Interface Bus, and
standardized as the IEEE-488 bus.
