Xerox Phaser 340 User Guide

There are three printing press color correction options.  Each press option 
conforms to a different printing standard.  Use a press option if you are 
previewing work for a four-color job to be printed on a printing press.  These 
options simulate a four-color commercial printing press, not solid spot 
colors, such as PANTONE Colors.         

If you are selecting PANTONE Colors in your application, use 
the None option; see page 6-4Turning off all color corrections for 
details.  Also, use the None option with other color management 
systems, such as EfiColor.
