RGB Separation

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 (output) or is first converted into the gamut of
another digital printer or 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 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
N :
OTE
Output Profile or CMYK Simulation Profile print options.
• converts all RGB colors into the CMYK color space of your printer (when
Output
set to the printer's default), or a customized CMYK color space for your printer
(when set to Output 1-10).

simulation (select the desired simulation with the CMYK Simulation Profile print
option).
This feature is not available with the PCL driver.
