Color Management Guide
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.
