With RGB Source set to None, PostScript RGB data that contains a source color 
space definition is converted using the CRD specified by the Rendering Style option 
(see page 1-5). NonPostScript RGB data and PostScript RGB data that does not 
contain a source color space definition is converted using a general undercolor 
removal conversion method.

This feature is not available with the PCL driver.

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 Fiery 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 copier (Output) or whether it is first converted into the 
gamut of another digital printer or a press standard (Simulation). 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 copier can simulate 
the behavior of that device.

RGB Separation is also useful for prepress applications. For example, it lets you 
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 printing 
condition. When the desired printing condition is found, you can then convert the file 
to CMYK, if desired, using the same CMYK simulation profile that was used during 
the experimentation. 

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

Output Profile or CMYK Simulation Profile print options.
