RGB Separation
The RGB Separation option determines how RGB colours (as well as Lab and XYZ
colours) are converted to CMYK. The name of this option is meant to be descriptive,
since the option defines the colour spaces that will be used by the ES3640e MFP 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 (see
output profile ) 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 ES3640e MFP 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.
•
Output
converts all RGB colours into the CMYK colour space of your printer (when
set to the printer’s default), or a customized CMYK colour space for your printer
(when set to Output 1-10).
•
Simulation
converts all RGB colours into the CMYK colour space for a specified
simulation (select the desired simulation with the CMYK Simulation Profile print
option).
