QTR-Quadtone RIP

I wish to "dedicate" my new P800 printer to Matte papers, however I also print dig negs on Pictorico film.

My experience with my R1800 printer and Eboni MK ink and dig negs is the "grain" and smoothness is fine. However, the R1800 is a 1.5 picoliter drop size versus the P800 3.5 picoliter drop size.

So my Question: 
Would MK Epson ink on the P800 (P600) give as good results as PK ink dig negatives for Cyanotype, VDB, and Pl/Pt Alt processes?

Thanks and any thoughts appreciated.
