Understanding color 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 Fiery—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 Fiery 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 Fiery color management system in
combination with the color management systems on Windows and
Mac OS computers.
