Hello Mr. Thomas Knoll,
this mail refers to a mail you posted a few month ago to the colorsync-users
mailing list. The basic message of your mail deals with the non-ideal
circumstances mainly in tasks of perceptual rendering, meeting my point of
view. Even though aware of the fact that programming rendering intents and
colormanagement algorithms is not "easy", I am kind of bothered by the
different results given by different profiles created by different programs,
even if based on the same measured data. The predictability proclaimed by
colormanagement becomes unpredictable by sending out device-independent data
without knowing which program created perceptual rendering to the final
output device.
You mentioned adobes "black point compensation" as only non-standard CM
process. In my opinion and based on my experiences, relative colorimetric
rendering with BPC on gives best results if the destination space is
similar and/or a little bit smaller than the source space, appropriate for
most high quality printing objects. (Why "mapping gamut" if not really
nessecary?)
But: nowhere else except in adobe products BPC is supported, so it is
impossible to render with this rendering-priority in a colorserver or
similar applications.
My question: is there any other solution or is there a workaround to this
reality or is there another reality, maybe provided by adobe?
Thanks in advance for your time. Respectfully, Andre Schuetzenhofer
