QTR-Quadtone RIP

I use Mac OS X (Panther), an Epson 2400 ans Silver Rag.  I do not get neutral / cool tones 
in my B&W prints, My prints come a bit greenish (very reminicent of the old Gallerie B&W 
paper for those who have used it in a wet darkroom).

I have tried all sorts of combinations using the blend mode but no success in getting 
neutral tones.  I use the Lustre Ilford curves which are provided with QTR.  

Does anybody have the proper curves for the Silver Rag, and how do we load them into 
QTR?

Thanks for any help

Silver Rag is a very warm tinted paper which purpose is to simulate
the old baryt papers like Agfa portriga. Also the black and neutrals
in the 2400 printer are on their own a bit warm when printed on
neutral papers. 
So this combination is not the best if you want neutral to cool print
results. Try Innova fibaprint gloss white. This is the same kind of
paper but not warm at all.

Hope this will help,

Steven.
