G-6 Glossary

presentation graphics rendering

A color rendering style that creates

saturated colors but does not match

printed colors precisely to displayed

colors. It is appropriate for bright

saturated colors used in illustrations and

graphs.

process colors

The four colors used in printing to

simulate full-spectrum color images:

Cyan, Magenta, Yellow, 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 printers.

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 Fiery 3850C 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.
