Rgb Separation - Xerox DocuColor 12 Color Manual

1-8 Fiery Color Management
• instructs the Fiery to allow the RGB sources you defined elsewhere, such as in
None
the application, to be used. When you set RGB Source to None, the appearance of
colors will not be independent of the file type. For example, RGB EPS files will look
different from RGB TIFF files.
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 1-6). Non-PostScript RGB data and PostScript RGB data that does not
contain a source color space definition are converted using a general
removal (UCR)

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 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/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 copier/printer 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
condition. When the desired printing condition is found, you can then 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.
