application
If the application allows you to define colors in RGB, determine
whether it converts the RGB data to CMYK before sending it to
the Fiery. If it does, this will determine which ColorWise print
options affect your job.
For example, if the application converts RGB black (defined in
the document as R0%, G0%, B0%) to four-color CMYK black
when it sends the job to the Fiery, the option you select for the
Pure Black Text/Graphics print option has no effect when you
print the job.

If you define colors in RGB and print directly from the
application, the application converts the RGB data to CMYK
before sending it to the Fiery. This conversion by the
application determines which ColorWise print options affect
your job.
For example, if the application converts RGB black (defined in
the document as R0%, G0%, B0%) to four-color CMYK black
when it sends the job to the Fiery, the option you select for the
Pure Black Text/Graphics print option has no effect when you
print the job.
