PostScript language file format
PostScript is a page description lan-
guage that is built into many desktop
printers and virtually all high-end print-
ing systems. Because it is built into so
many printers, most Macintosh, Win-
dows, and UNIX® application can create
PostScript files for printing.
PostScript files can describe a single
page, but typically they represent entire
documents.
The first version of the PostScript file
format, PostScript Level 1, represents
both grayscale vector graphics and
grayscale bitmap images. The second
version, PostScript Level 2, represents
color as well as grayscale vector and
bitmap images, and supports RGB,
CYMK, and CIE-based color models for
both vector and bitmap graphics. (Some
PostScript Level 1 files also represent
color with extensions to the PostScript
language that were generalized in Post-
Script Level 2.)
