G-6 Glossary
colors. It is appropriate for bright
saturated colors used in illustrations and
graphs.
process colors
The four ink colors used in printing to
simulate full-spectrum color images:
Cyan, Magenta, Yellow, and blacK
(CMYK).
QuickDraw
Graphics and display technology built
into Mac OS computers. QuickDraw
applications rely on QuickDraw (rather
than the PostScript language) to send
text and pictures to copiers.
raster image
Electronic representation of a page or
image using a grid of points called pixels.
rendering intent
The 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 (ppi) in a
bitmap image or the number of dots per
inch (dpi) that a device can render.
RGB
An additive color model that makes a
range of colors by combining red, green,
and blue light, called the additive
primaries. Commonly used to refer to
the color space, mixing system, or
monitor in color computer graphics.
simulation profile
The simulation profile describes the
color characteristics of another print
device, such as a printing press, that you
want the ColorPASS to simulate.
solid color rendering
A color rendering style intended for use
when color accuracy is crucial.
Unprintable colors are mapped to the
closest printable colors. Solid color
rendering does the best job of preserving
the saturation of displayed colors.
source color space
The color environment of the
originating source of an image, including
scanners and color monitors.
source profile
A profile used by the color management
system to determine the characteristics of
the color values specified in a source
digital image.
spectral light
The wavelengths of electromagnetic
radiation emitted by a given light source
that can be seen by the human eye.
spot color
A color that is printed on its own
separation plate when separations are
specified. A spot color is printed using a
custom ink for that color, in contrast to
