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 RGB image data
according to a specified source profile and adjusts both RGB and
CMYK data according to a specified output profile , also called a
destination profile by some color management systems.
The source profile defines the RGB color space of the image’s
source—characteristics such as the
white point , gamma , and the
type of phosphors used. The output profile defines the gamut 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 space and the color space of the output device.
The Fiery allows you to specify default and override settings for
the source color space information and the output profile
information (see the
Color Guide Chapter 1 ). When you use these
settings, you do not need to use the features of other color
management systems. Your Fiery software includes
ICC profiles
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
Chapter 1 of the
Color Guide .
