Hi Bruce,

Actually for printing there is only one curve and it has 100%K-to-100%K 
builtin
so I don't think the various intents ought to make a difference.

In soft-proofing however there are many profile conversions happening 
and its
hard to tell from the PS selections where are the mappings go.

So the more I think about it, it sounds like your workflow is 
introducing too many
conversions somewhere.   I think you are somehow printing the Ink Black 
simulation
of the soft-proof but I'm not sure how that could be happening.   Are 
you printing
directly from Photoshop using the Print with Preview screen?  Might you 
be
printing the proof instead of the source file?   Are you printing with 
the QTR driver?
The more you can elaborate your workflow the better.

Roy
