Olaf, how would you go about using PDFfixups to perform an ICC
color transform using the Perceptual rendering intent?
you would have to set the rendering intent first, using the Set
Rendering Intent fixup
I'm playing with it, but I can only get the PDFfixup to convert RGB
elements (I'm going into CMYK), and I can only get a RelCol
rendering. What conditions am I not meeting?
in the setup for the Color Conversion fixup you ave two tabs;
- the "Destination" tab is for setting up the default source
profiles (for device process color objects should they have to be
converted), some conversion strategy settings (for example black
point compensation) and the destination
- the "Conversion settings" tab is for defining which objects to
convert, and how to convert them; IMPORTANT: you can have more than
one subsetting in this tab - just click on the plus sign in the right
of this tab, and anither setting will be there to be configured;, for
example you could decide to convert all images which are calibrated
(i.e. have a profile associated with them n the PDF), and then
uncalibrated images (i.e. they are device RGB, and the conversion
would use the default RGB profile as the 'assumed' source profile),
and you could add yet another setting to decalibrate all calibrated
CMYK objects (i.e. discard the source CMYK profile(s)).
Also tried a fixup that changes the RI to Perceptual, then tried
both Convert Colors and a PDFfixup. Couldn't get it to work that
way either. Is there some more thorough documentation somewhere?
you have to make the necessary fixups a part of a Preflight profile,
and then running the profile will apply the fixups in it.
Does that make any sense?
