QTR-Quadtone RIP

I've just run my first few prints via QTR on a 2100.  I'm just amazed
by the quality of what Roy's done, and after a couple of years of
listening in on DBWTP, I'm deeply appreciative of his trailblazing and
generosity to the community.

The prints are smooth, dotless, subtle, and *easy*.  Thank you, Roy. 
My 50 bucks is on its way.

Now for the question.

I'm not getting anything like a match -- tonality and contrast --
between screen and print.  Two calibrated monitors on two different
machines show significantly higher contrast and lighter mid-tones than
the prints.  I've played with gamma and ink limit adjustment in QTR,
but they don't go nearly far enough to solve the problem.

(I'm using standard UC inks and standard EEM-equivalent paper.)

I'm assuming, at this point, I'm going to have to apply a curve,
either to the image in PS or directly in QTR.  But, frankly, I don't
really know what I'm doing there, and I don't want to spend weeks
profiling.  

Does anyone have any newbie-friendly advice?

If this has been addressed before, I'd be much obliged for a pointer
to the right thread.

Thanks in advance.  --Houston
