I've printed on a wide variety of vinyls on my PC-600 but primarily on Mactac 9800, have come up with some very cool results printing on Coburn Specialty films & SignGold. Make sure whatever you print on has a smooth finish as to not chance damaging the print head. Real life tests showed Z9 prints failed miserably, faded out totally within 2 years without lamination and around 3 with lam. I have prints out there for over 6 years done with Roland ribbons that still look absoloutly beautiful as a matter of fact I ran into these trailers just the other day that I had done over 5 years ago, I examined decals closely and they looked great, no vinyl shrinkage & no noticible color fade, nothing wrong with the prints at all, the prints were done on Mactac 9800 white with CMY process color Roland ribbons w/Frog Juice liquid lam. Oh and the average is 8 sq ft per ribbon at full coverage, a little less from spot color ribbons.
