color management systems.
The source profile defines the RGB color space of the image’s source—characteristics 
such as the

 used. The output profile 
defines the gamut of an output device, such as a printer. The Color Server (or the 
host-based CMS) uses a device-independent color space to translate between the 
 
 
The Color Server allows you to specify default and override settings for the source 
color space information and the output profile information (see the 
 
Color Guide
 
). 
When you use these settings, you do not need to use the features of other color 
management systems. Your Color Server software includes 
 
 
other color management systems, although conflicts may arise when the Color Server 
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 Color Server simulation feature is described in detail in the
 
Color Guide
 
.
The type of print job and the final output device—Color Server or offset press—
determines the workflow that allows you to achieve the best results. For information
