Hi Antonis
The inks I'm using are MIS UT ink with Eboni black, in a Epson 1160, 
using Paul Roark UT11 curves. The papers are EAM and PhotoRag. The 
operating system is Mac OS X version 10.3. The Epson print driver is 
the latest from the Epson site. 

What you say is interesting but not quite sure how you would go about 
it. The full ink set prints are printed as per Paul's instructions, 
with his curves put on a layer in PS. I keep the files 16 bit, RGB 
mode. All driver/PS settings are as his instructions. They print just 
fine until you compare them to BO. The full set prints just seem a 
little flat compared to BO. Maybe its the blue ink used in the full 
set ink to control tone thats causing the problem. Now if you know 
what you are doing I guess you could alter PRs curves so blue does'nt 
get used and see what results. However I do not understand how these 
curves work. If you have any ideas I would be more than happy to have 
a go. Certainly experimenting is part of the fun for me. I would love 
to get these inks to print better. I really do not want to buy into 
another system particularly as MIS are such a brillant company.

One last thing as you would expect PhotoRag prints better than EAM 
but then it does BO too!!!

I really cannot see how an amateur such as myself could better PRs 
curves. After all he knows what he's doing I don't.
