Xerox DocuColor 12 Printer with Fiery EX12 Fascicule

A standard developed by CompuServe 
for bitmap graphics of up to 256 colors 
and used for posting photographic 
images on the Internet or intranet pages; 
rarely used for professional printing.

A smooth transition between two 
different colors or two shades of a color.

See GDI.

A printing technology that uses an 
etched cylinder that has been immersed 
in ink. The ink that remains in the 
etched areas is applied to the paper. The 
non-etched surfaces of the cylinder are 
non-printing areas. 

In shadow, midtone, and quarter-tone 
areas where all three process colors 
(C, M, Y) overprint, the gray 
components of those colors are 
reduced and replaced by black. This 
improves wet ink trapping and reduces 
ink costs in process color printing.

A method for representing an original 
continuous tone image using a pattern of 
dots, lines, or other patterns. 

A color model where each color is 
represented by its hue, saturation, and 
brightness components; supported by 
most color applications.

An industry standard color profile 
format developed by the International 
Color Consortium (ICC) that describes 
the color capabilities, including the 
gamut, of a color device based on the 
differences between an ideal and the 
current device. The ideal is often 
provided by the manufacturer as a color 
reference file. ICC profiles are 
implemented on Mac OS computers in 
ColorSync and on Windows computers 
in Image Color Matching (ICM). The 
Color Server color management system, 
ColorWise, supports ICC profiles.

Raster-based film output device; a high-
resolution laser output device that writes 
bitmapped data onto photosensitive 
paper or film.

A graphics file format defined by the 
Joint Photographic Experts Group 
committee of International Standards 
Organization (ISO); a standard for 
digital compression of still image graphic 
data.
