It appears that the 3880-PiezoDN-Pos-Master.quad, 3880-PiezoDN-PD-Ox-IJM.quad, and the 3880-PiezoDN-Master.quad ink curves are identical (as read in QTR-Curve view). If this is correct, what are the differences? I assumes that the Master quad would be used if one was starting a negative alt process other then Pd (in which case the PD-Ox-IJM.quad would be used. And the Pos-Master.quad would be used for a positive alt. process, e.g. gravure.
I am now confused :-).
