QTR-Quadtone RIP

Hello dear members,
i am new here at this group and i am happy having found you.

I am using an EpsonR1400 with Claria Inks and i found some nice curves which give well results with some papers i am using.
I am slowly getting into this RIP and its really great. At the moment i have a pack of Canson Baryta 310 at home, but the results with this paper arent really good.

Has anybody a tip which curve maybe will work? I have the curves from our Database and a set of curves by Paul Roark. Of course i can try and try... A good advice will save ink, maybe. 
Or, does anybody have a proper curve for this paper?

Any answer is appreciated.

Greetings from Cologne/Germany
Bob
