I'm experiencing similar issues. Previously I was using the Brandin Curves
on an 1160. No posterization, but murky, low contrast shadow detail. I'm now
using Paul's curves on a 1280 (PC). There seems to be a lot of printer to
printer or system to system variations, so in some cases, a bit of curve
tweaking might be necessary.

I've found that (on my system) the shadows print much lighter that what I
see on my (calibrated) monitor. I've done a slight tweak of the RGB portion
of the warm curve, dropping the toe and lower mid tones slightly. The
resulting print matches the screen image, and the blacks are a lot stronger;
quite an improvement, really. This is a crude adjustment, but it does show
the potential of print quality you can get from Paul's curves.
