QTR-Quadtone RIP

Hi,

I'm printing on EPSG using the QTR curve for UT2 inks and Premium
Luster (there is no canned EPSG curve that I'm aware of)My prints are
coming out significantly lighter than the same setup using the Roark
curve. Should I be using Eboni as opposed to Photo Black. Are there
any QTR curves available for EPSG or for the new Innova Fiba Gloss?

Thanks,

Mike Kitei
