Chris, are we saying he same thing differently? Doesn’t a PDFs
embedded profile (output intent) become the source profile (working
space) when you open it or am I using a term incorrectly?
The Output Intent only applies to PDF/X documents. And they aren't
always embedded profiles, they can be externally referenced (unless in
PDF/X-2 or X-3 there is device independent data in the PDF, then the
Output Intent printing condition must be embedded as an ICC profile).
For PDF/X documents the Output Intent is the source profile for
untagged objects (unless you uncheck the box in preferences telling
Acrobat to do so).
For non PDF/X documents, Working Spaces are source profiles for
untagged objects.
As to the use of the Applying the Working Space or not, It’s no longer
an issue if you are using Acrobat v7, but for v6 (which isn’t going
anywhere anytime soon (come on Enfoucs with Pitstop support)), I would
think that Adobe would be assuming something; like Photoshop with
color management turned off; it’s still ALWAYS color managing. (I
remember past threads that it was resolved that Colorspace X was being
assumed when CM was off; I forget what it was).
I'm not sure what's going on. All I remember thinking is that it was
pretty useless.
