Xerox Phaser EX7750 Reference Guide

The Frequency and Angle settings in the Application Defined halftone screen are used 
regardless of whether the setting for Combine Separations is set to On or Off. For 
special instructions for printing separations with Photoshop, see 

In general, using halftone screens is not recommended because the print output 

will have visible dots of toner rather than smooth blends. Use halftone screens only 
when necessary to achieve a specific style of print output.

You can take the following steps to ensure color accuracy:

• When saving EPS files, do not include PostScript Color Management information. 

This minimizes the risk of conflicting data and multiple color conversions. 
PostScript Color Management causes your CMYK and RGB colors to be interpreted 
by the Color Server as though they were supplied in the Lab color space and, as a 
result, processed by CRDs, rather than your simulation settings.

• Include ICC color information in files. ColorWise does not conflict with this 

information, and such data is useful for identifying the specific color space used by 
your files.

• Do not include halftone and transfer functions.

• Turn off color management in the printer driver. 

On Windows computers, if the printer driver offers Image Color Matching options, 
select Printer Image Color Matching.

On Mac OS computers, set the printer driver to include no color management 
commands at print time (see the 

).
