Digital BW, The Print

There is one thing here in the Qimage -> QTR workflow that I don't
understand - colour or dot gain profiles.

I assume if you print PSCS -> QTR a grayscale image which has, for
example, a 20% DG profile, then QTR does some sort of conversion. (If
this is not right, someone please correct me, as this is not the way
that I usually print.)

However when Qimage prints to file for input to QTR, it outputs an RGB
image, which will generally have some sort of colour profile attached.
 What does QTR do with this? 

Perhaps if I was on a Mac, all this would be more obvious.  I read
that recent thread about the problems with B&W workflow, which I only
partly understood.  

Colour management is well documented (e.g. Blatner & Fraser), but not
really B&W tone management, at least not that I have seen.  Is there
something about this topic somewhere that I can read?
