Xerox Phaser EX7750 Reference Guide

Use the following information to implement alternative, more complex, color 
workflows with Photoshop.

To use PostScript color management with Photoshop 6.x, choose PostScript 

Color Management from the Profile menu in the Photoshop pane of the printer driver.

Selecting the PostScript Color Management option when saving either a CMYK or 
RGB EPS file prompts Photoshop to embed PostScript color information—which is 
independent of 

s—in the resulting document. This information is 

intended for PostScript devices like the Color Server.

When you print an RGB EPS file that contains an embedded profile to the 
Color Server, you can use the working space information from the embedded RGB 
profile as an RGB source definition for Color Server 

. To use this source color 

space information from the embedded profile with Color Server CRDs, choose None 
as the ColorWise RGB Source when you print. This applies when you print directly 
from Photoshop, or when the same RGB EPS file is output from another application.

To override the embedded profile in an EPS file using an RGB Source definition made 
available by the Color Server, choose anything except None as the Color Server RGB 
Source Profile.

If you select an RGB 

 and decide to use PostScript Color Management, 

Photoshop sends RGB data to the Color Server along with PostScript color 
information defining this RGB color space. When you select PostScript Color 
Management, a CRD is used to perform color conversions to CMYK.

The included RGB source color space information is overridden by the 

ColorWise RGB Source option unless it is set to None. The ColorWise Rendering 
Style option specified will take effect if the ColorWise RGB Source Profile option is set 
to None.
