Hi Matt.
Sorry, but no, that is not what's happening.
When you do that, you are actually completely switching to the Custom CMYK
engine and a completely different and unrelated separation engine: you are
no longer using either the ICC profile you started out with or a modified
version of it.
The variable results that you mention are due to the changes in the Custom
CMYK settings, and have no relation whatsoever to the ICC profile you had in
the beginning (be it Euroscale Coated or any other one).
It's confusing at first, but that's the way it actually works. ICC profiles
and the Custom CMYK engine do not mix, at least not in Photoshop up to this
point. The future may bring changes, but so far no dice.
Regards.
