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 because the option
defines the color spaces that are used by the Fiery EXP8000/50 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 digital press (
) or is first converted into the gamut of another digital
printer or press standard (
). This feature helps make one device behave like
another for RGB data. For example, if a high-quality ICC profile is available for another print
device, the digital press 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 that you used during the experimentation.

:
Use the RGB Separation print option in conjunction with the Output Profile or
CMYK Simulation Profile print options.
•
Output
converts all RGB colors into the CMYK color space of your digital press (when
set to the printer’s default), or a customized CMYK color space for your digital press
(when set to Output 1-10).
•
Simulation
converts all RGB colors into the CMYK color space for a specified simulation
(select the desired simulation with the CMYK Simulation Profile print option).
RGB Source Profile
The RGB
setting allows you to define the characteristics of the RGB data in
your document so that the appropriate color conversion occurs on the Fiery EXP8000/50.
Commonly used monitor color spaces are available from the printer driver and the Fiery
EXP8000/50. For others, use ColorWise Pro Tools Profile Manager to download custom
monitor or scanner profiles.
When you specify a setting other than None for the RGB Source Profile, the Fiery EXP8000/
50 overrides
definitions or profiles that other color management systems
may have specified. For example, if you specified a ColorSync System Profile on your Mac OS
computer, the RGB Source Profile setting overrides it. In cases where you do not want this
setting to override another specified source color space, choose None.
