Editing the output tables
without the proofing tables will change your prints, but not your preview. If
your image looks good on screen, but lousy in print, thats what you need to
do. If your prints are perfect, but preview wrong on screen, you would do the
opposite, and edit the return (proofing) tables only. And always beware of
Heidelberg profiles and workflows, which do not play by the usual rules with
the different intents.
Printopen 4 and ProfileMaker 3 behave the same though the gamut
mapping is different. of course.
In general a profile should only be edited to change the perceptual
gamut mapping. This is a way of automating color corrections.
The colorimetric table should not be edited. Rather, it should be
left alone. If the printing process changes, build a new profile.
The idea of editing the profile if the print looks right and the
preview wrong is kind of tricky advice.
I could name a lot of reasons why the preview looks wrong, including
wrong software setup and buggy software.
It's still true that the very last thing to do is to think of editing
profiles, and especially editing the colorimetric transforms used for
previewing on the monitor and proof printer.
Better start with getting the studio lighting right, checking the
monitor, setting up applications, linearizing, calibrating and
characterizing the digital color printer ...
