Digital BW, The Print

I was printing with Ultrachrome inks in BO mode and I get great B&W 
print. But because of the cost I bought a month ago CFS and UT7 ink 
from MIS for my Epson 2100. Now I have the same problem like Lara. 
There is some solarisation on the prints. Especially from mid to 
lighter side of midtones. I follow the instruction of Paul, but 
still there is something which makes me unhappy. If I check ICM or 
NCA I cannot control Gamma because the box diseppeared. As paper I 
used EEM. Now I ordered HM PhotoRag. I would like to try this papr 
too.
To Paul: Do you also have curves for Somerset Velvet and Somerset
