Terminology
Specific terms are explained as they are introduced. However, the following general
terms are used throughout:
•
PostScript (PS)
—A computer language designed as a page description language. The
ColorPASS uses this language for imaging the page and for communication with
applications and with the print engine.
The term “PostScript” can also be used to refer to PDF data jobs. PDF is a
structured form of PostScript that provides the ability to preview, scale, and reorder
pages. Where applicable, the term “PDF” is specifically used to refer to PDF data or
jobs.
•
Job
—A file consisting of PostScript commands and comments that describe the
graphics, sampled images, and text that should appear on each page of a document,
and the printer options that should be used in printing, such as media or color
rendering style.
•
Spool
—Write to a disk. Usually used in this manual to refer to a PostScript print job
being saved to the ColorPASS hard disk in preparation for processing and printing.
•
RIP
—Acronym for raster image processing, which changes text and graphics
commands into descriptions of each mark on a page. In common use as a noun, a
“raster image processor” (RIP) is the computer processor that performs this function.
•
Print
—The process of rendering, or imaging, a page or a job on a printer.
These concepts can explain how the ColorPASS and the copier work together as a
powerful printing system. The ColorPASS RIP changes text and graphics commands
in PostScript into color specifications for each dot of toner deposited on a page by the
copier.
