I think I raised that question myself. But right now the 
Fine Art Paper >250 gr media setting that uses the quad 
inkset gives a higher Dmax than the Matte Litho Realistic 
media setting that leaves PK out of the mix, both used on 
all matt HM coatings. The PK may not do much in bridging the 
gap between middle grey ink and MK (which was what made me 
question its use) but it could boost the Dmax by running 
along on the last part with MK. As long as the curves are 
hidden in the Z3100 driver it is hard to find out.
