QTR-Quadtone RIP

Hi all,

I just received the UT-3D inks that I plan to use for my Epson 2100 
with Enhanced Matte and Photo Rag. I can get started using the icc 
profile for Photo Rag on Paul's website. But I like to use QTR curves 
as well. I've not yet found any curves for these combinations. Any 
pointer? 

If not, I'm happy to make my own curves but, given my limited 
experience so far, I could use suggestions for a good starting point. 
Perhaps the UT7 curves? I recall to have read that the warm carbon 
tones are similar/identical to the UT-3D curves.

Thanks,

Joost
