converted to the gamut of the printer. Whether performed by the
Fiery or a host-based CMS, the process of converting color data
for a printer is the same: the CMS interprets
according to a specified
CMYK data according to a specified
destination profile by some color management systems.
Input data
The source profile defines the RGB color space of the image's
source—characteristics such as the
type of
an output device, such as a printer. The Fiery (or the host-based
CMS) uses a device-independent color space to translate between
the source color
The Fiery allows you to specify default and override settings for
the source color space information and the output profile
information (see the
settings, you do not need to use the features of other color
management systems. Your Fiery software includes
for use with other color management systems, although conflicts
may arise when the Fiery CMS is used in conjunction with a host
CMS.
You can also use color management systems to adjust color data
to the gamut of an output device other than the one to which you
are printing. This process of simulating another output device is
commonly used for proofing jobs that will be printed on an offset
press. The Fiery simulation feature is described in detail in
