B-3

Relative

Colorimetric

A rendering intent that maps colors to the nearest hue relative to
the white point of the media. The gamut mapping strategy will
clip out-of-gamut colors to the gamut boundary.

Rendering Intent

As part of the Profile Color Conversion in the Profile Connection
Space, rendering intents can be applied to the job to achieve
specific results. The DocuSP controller provides 5 rendering
intents:

Absolute Colorimetric

Relative Colorimetric

Perceptual

Saturation

Pure

RGB

A color space model that defines the relative amounts of Red,
Green, and Blue light in the image. The RGB color space is
generally seen as an input profile; the printer will need to convert
RGB to CMYK in order to print the job.

Saturation

A rendering intent that maps RGB CMYK to CMYK. The G is the
printer’s G, the B is the printer’s B, and the R is a saturated Red.

Source Profile

The color profile with which the job was created at the client
workstation prior to submission. It is often embedded as part of
the PDL, but if not embedded, a source profile can be assigned
by the DocuSP controller at the job or queue level.

Spectro-

photometer

A tool which measures the quality of the printed test pattern and
enables calibration of the printer. This is accomplished by
measuring the spectral wavelength of light reflected from a
substrate (surface).

Spot Color

Spot colors are selected from books or charts that contain
printed color samples, each of which is identified by some
number. Usually, the numbered colors are also described in the
CMYK system. One widely used numbering scheme is known as
the PANTONE® Matching System, or PMS. The DocuSP
controller contains a spot color editor that provides PANTONE®
Coated and Uncoated color definitions.

sRGB

Standard (device-independent) RGB.

SWOP

Standard Web Offset Press. A type of printing press for which the
DocuSP controller provides an emulation.

TIFF

Tagged Image File Format.
