Glossary
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 devices.
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
See simulation profile.
simulation profile
The simulation profile describes the 
color characteristics of another print 
device, such as a printing press, that you 
want the Color Server 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 a colored element, 
including scanners and color monitors. 
source profile
A file 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. 
spectrophotometer
An instrument commonly used in the 
graphic arts industry to measure spectral 
light according to a specified standard.
