Xerox Phaser EX7750 Reference Guide

The Color Server is highly optimized for the specific printer it supports. ColorWise 
addresses issues unique to your printer, including screens, individual toner response, 
interactions among toners, natural smoothness of blends, and the capability to render 
spot and custom colors. The Color Server distinguishes text and graphics from image 
elements, so that black channel information is preserved while parameters used for 
CMYK 

 are maintained.

The recommended standard color workflow uses ColorWise calibration and color 
management. The Color Server comes into play near the end of the color workflow. 

For this workflow:

• Bypass any color management in the applications and printer drivers.

This ensures that the colors you selected reach the Color Server and ColorWise 
in a usable form. Keep in mind, however, that ColorWise fully supports color 
management from applications and printer drivers (see 

• Set the CMYK Simulation Profile option in ColorWise to match the CMYK color 

space used in the application to select the colors. Any CMYK Simulation setting 
(except Match Copy, if available) applies calibration, so the response of the printer 
will appear to be stable.

The recommended values for CMYK Simulation are 

 in the U.S., 

in Europe, and 

 in Japan—choices that reflect the color standard for each 

region. If colors have been selected specifically for your calibrated Color Server, set 
CMYK Simulation to None.

• Set other ColorWise print options as appropriate. For a list and descriptions of 

ColorWise print options that affect CMYK, RGB, spot, and other colors, see the
