QTR-Quadtone RIP

Mike

Actually trying to understand the "logic" of the settings.  
I see QTR is basically set up for a gray second or third ink (and the relative densities make sense) and my question related to a color ink as a second ink probably doesn't make sense with QTR.

What I have been playing with is how to eliminate the greenish cast I get with printing with the PK only Epson Black ink.

Thanks, Terry
