Xerox Phaser EX7750 Guia De Referência

A file that describes the color 
characteristics of a printing device. 
The output profile is associated with 
a calibration target that defines the 
expected density response of the device. 

Material used in making computer 
monitors; phosphors glow and emit red, 
green, and blue light when struck by an 
electron beam, thus creating an image.

A color rendering style that preserves 
tonal relationships in images. 
Unprintable colors are mapped to 
printable colors in a way that retains 
differences in lightness, sacrificing color 
accuracy as necessary.

The smallest distinct element of a raster 
image. The term is a combination of the 
words “picture” and “element.”

A device-independent page description 
language developed by Adobe, which is 
used to print and display pictures and 
text. PostScript 3 includes many 
enhancements to older versions of 
PostScript, including improved image 
quality and color.

A file containing information about 
a particular PostScript print device’s 
capabilities and restrictions. The 
information in the PPD is presented 
via the printer driver.

A print made from a set of film 
separations or other file to simulate the 
results of printing. A prepress proof is 
the last opportunity to catch problems 
before the print job goes to press.

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.

The colors used in printing to simulate 
full-spectrum color images: Cyan, 
Magenta, Yellow, blacK (CMYK).

Systematically describes how a color 
maps to a particular space. By 
identifying a source profile and an 
output profile, you initiate the 
appropriate workflow to maintain 
consistent color values.
