B-2 Color Management Guide
Destination Profile The color profile that converts PCS to the output device’s color
space. In other words, a destination profile can be sent to the
printer.
Gamut The complete range of colors a device can produce. Most
printers have unique gamuts compared to other printers. Often,
however, the printer can emulate the output of a different printer
through use of a Color Space Transformation.
GCR Gray Component Replacement: the process of removing the
graying component, or dirtying color, from a color and replacing it
with black. For example, a red containing 100% magenta, 80%
yellow and 20% cyan without GCR might contain 90% magenta,
70% yellow, 10% cyan, and 10% black after GCR has been
applied.
Halftone A pattern of dots of varying sizes applied to an image of varying
tones, or same-sized dots applied to a tint of color. Used to
reduce moire and other artifacts of the printing process.
ICC International Color Consortium
JPEG An image file format which is in RGB color space. The .jpg files
in a print job will need to be converted to CMYK prior to printing.
Lightness The perceived reflectance of a surface.
Matte Matte refers to an attribute of a stock which is a flat color with no
glossiness. Matte stocks tend to appear halfway between
uncoated stock and coated stock.
OPI Open PrePress Interface: the process of substituting full-
resolution images residing in a repository for low-resolution
images at RIP time.
PCS Profile Connection Space. DocuSP employs XYZ as its Profile
Connection Space. XYZ is a color space model that maps colors
according to human eye response.
Perceptual A rendering intent that maps colors to the nearest hue relative to
the white point of the media and compresses the printer’s gamut.
The intent maps colors relative to each other, allowing more
distinction between colors and increased shadow detail.
Press Emulation The DocuSP controller can emulate outputs from other types of
printers. Examples include SWOP Fogra Matte, Fogra
Uncoated, Fogra Coated, Commercial Coated, as well as either
iGen3 CMYK or DC 2000/6000 CMYK (depending upon your
printer).
Pure A rendering intent that warps colors close to a pure colorant (C,
M, Y, K, R, G, and B) to the pure colorant.
