>99% Canon (8400 now), but 1% is a second hand 7880, loaded with cone Piezo DN ink set. The Canon runs 10 hours a day, and gets through heads every 6 months.
The Epson is used for making digital negatives, and gets run 2-3 hours every few of weeks. I run a nozzle check, print a granger rainbow (using QTR print tool), then print the negatives onto Pictorico UP OHP film.
The Canon makes beautiful exhibition prints (always genuine ink - I don't have the luxury of potentially having prints fade early), but the Epson makes negatives that are in a different league.
The Cone inks don't give you the option for colurised negatives, but do make damned good negs.
How much do platinum salts cost these days, and how many hours do you invest in the final print production?
