Ernst, 

There is this debate going on that when the Z driver adds the PK ink
to the MK rag paper output (quad as apposed to Tri black) that you're
not really gaining anything, and could possibly even create a very
difficult mix to linearize, given the unequally spaced density
dilution of the Pk ink in a Quad set up like that.

What is your take on that having worked with it? I assume a carefuly
controled mono rip could take more advantage if it better than the HP
driver? Is the additon of the extra PK black doing anything for you vs
not using it on media such as say Photorag?
