Clay, 
I'm the original poster so I'm obviously looking for solutions rather
than being able to dish out advice. But what I've learned so far is
that the Photo Black ink (in particular) sits on the surface and has a
different reflectance to the paper surface and that causes the
'solarized" appearance particularly where the dark and medium or light
tones meet.
