Digital BW, The Print

I was getting such good prints with the MIS quadtone inks in my 1160 using PS 7 in OS 9 I 
decided to switch to CIS when I upgraded to OS X and PS CS. Now I am not sure how to 
make the curves work. When I apply the curve I get a print that appears to have been 
solarized.

I print using the Print with Preview then I am not sure where to go from there - because 
the settings I use for colour on the 2200 do not seem to be working. If I don't use a curve I 
get a pretty good looking b&w print but I want to be able to make warm tone images on 
Crane Museo cards.

Is there a different workflow for PS CS and OS X?
