Introduction
Printer gamut
Different color reproduction techniques have different color capabilities, or
gamuts
.
Color transparency films have comparatively large gamuts, as do color monitors.
The color gamut that can be produced using process inks or
CMYK
toners on paper is
smaller. This is why some colors that can be displayed on a color monitor, especially
bright saturated colors, cannot be reproduced exactly by your Color Server—nor, for
that matter, can they be reproduced on a press using
process colors
. Moreover,
different printers have different gamuts—some colors your printer can produce cannot
be reproduced on an offset press, and vice versa. The following figure illustrates this
concept of differing gamuts.
You must account for the gamut of your printer when designing on a color monitor.
When printed, colors that fall outside the printer gamut are “mapped” to printable
colors. This process, referred to as
gamut mapping
, takes place when color data is
converted or adjusted to meet the gamut requirements of a printer.
The Color Server is specially designed to perform gamut mapping at high speed with
high-quality results. It provides these color management features automatically, using
either built-in default settings or settings you select for a particular print job. For added
flexibility, you can also use the Color Server color management system in combination
with the color management systems on Windows and Mac OS computers.
