QTR-Quadtone RIP

Hi,
I am trying to get some glop (epsonGO) to print through QTR. I'm running QTRv2.6.2 on Mac 10.5.7. printing with an Epson R1900. The inkset is UT3D parts, too long of a story :( . I have a good warm curve, LC and C mixed in the toner section, LK and PK mixed in the gray. And I have a good cool curve, LM and M in the toner with LK and PK in the gray. I combine these in the QTRprint dialog curve mix and love the results so far... 
Is there some code line or something added in the quad curve creation that will pour on the glop without trying to undercut the inks?

Thanks in advance, SteveO
