It may depend on your printer. I print to Agfa Copyjet to make digital positives. With my Epson 3800 I used PK ink. When I replaced it with an SC-P800 I discovered (which was confirmed by others) that PK ink was problematic in blocking UV. I recently tested MK, which held and dried fine on the emulsion of the acetate. The MK will be my preference now.
