What about driver settings:

Source: Adobe RGB or sRGB
Space: Same as Source
Custom, Color Controls, Automatic

Use Adobe RGB for your RGB space, and Gamma 2.2 for your grayscale space
(subject to correction from Jerry or Paul or Mike) it's working for my mix.

That's what it was for the Piezo/Gen blend, not sure about MIS.

I'd check the MIS site for latest curves and workflow info. Follow the links
for Paul's VT method.

My only gripe with your black-only method is that it mimics the grain of
your image, but it doesn't reproduce it. There is bound to be circumstances
where the two different "grain" sources conflict with each other. A good
quad setup will describe your image, not recreate it.

I also recommend trying over sharpening, as Tyler suggested. Not as a rule
per se, but certainly as a test. But first you've got to get rid of that
posterization, or you'll never get the right pear. As Jerry suggested, make
sure your inks are in the right positions. All suppliers have been known to
sell inks in wrongly labeled bottles. It's possible you got two bottles of
inks which are the same density!

I just participated in the 30 print exchange, and I can assure you none of
the contributors to that are suffering from posterization. It's not normal.
Don't settle!
