G-6 Glossary
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 iR C2100/2100S 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 process colors that are printed using
combinations of cyan, magenta,
yellow, and black.
Status T
A spectral response for graphic arts
reflection densitometers defined by
ANSI (the American National
Standards Institute).
subtractive color model
A system in which color is produced
by combining colorants such as paint,
inks, or dyes on media such as paper
or transparent film or acetate. All
printing devices use the subtractive
color model.
