QTR-Quadtone RIP

Would be very grateful for any advice on how to get started with
developing curves to address the common issue outlined below. Having
asked once before without result, I'd be particularly glad of any reply.

I've just run my first few prints via QTR on a 2100. 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, or any other good source.

Thanks in advance. --Houston
