Xerox Phaser EX7750 Leaflet

The RGB Separation option determines how RGB colors (as well as Lab and XYZ 
colors) are converted to CMYK. The name of this option is meant to be descriptive, 
since the option defines the color spaces that will be used by the EX7750 to “separate” 
the RGB data into CMYK values.

The two choices available for this option determine whether RGB data is converted 
into the full gamut of the printer (

) or is first converted into the gamut of 

another digital printer or press standard (

). This feature is helpful for 

making one device behave like another for RGB data. For example, if a high-quality 
ICC profile is available for another print device, the printer can simulate the behavior 
of that device.

RGB Separation is also useful for prepress applications. For example, it allows you to 
experiment with the appearance of an RGB scan under different press printing 
conditions, without having to convert the RGB data to CMYK data for each 
condition. When the desired printing condition is found, convert the file to CMYK, 
using the same CMYK simulation profile you used during the experimentation. 

The RGB Separation print option should be used in conjunction with the 

Output Profile or CMYK Simulation Profile print options.

•

converts all RGB colors into the CMYK color space of your printer (when 

set to the printer’s default), or a customized CMYK color space for your printer 
(when set to Output 1-10).

•

converts all RGB colors into the CMYK color space for a specified 

simulation (select the desired simulation with the CMYK Simulation Profile print 
option).

This feature is not available with the PCL driver.
