Here's the thing about the 3000- I got excellent, really almost perfect films on the Westjet film I linked to, with my own setting via the original epson drivers or, on the mac, with some gutenprint settings I worked out. No banding, no excess ink, no rough edges. Problem was, I had no rip to run a separations base workflow and had to manually breakdown each files color seps and, if I wanted dots, bitmap them in photoshop, replace in illy and then, after all that, print each file one by one. This is not an appropriate workflow for a busy shop obviously. And, without getting all up in some color profiles and massive curves adjustments natively in photoshop you don't have much for dot gain control. This is an issue on the non-wp film.
None of the rips I trialed could get as good of a film out of the 3000 as the above did, on any brand of either wp or non-wp film, and I think it's because nobody that I know of has written a rip that takes advantage of the the 1440dpi setting on the 3000. Understandable I guess, it is a pretty damn old printer so why bother. I sucked it up and moved on to a 4800. If I had a rip that got me that film quality on the 3000 I might never have left it but I got tired or screwing around with it. Networked, they actually do pretty darn good for themselves compared to the new models. It's hard to beat the roll feed/paper cutter deal on the 4800 though and the custom print size settings with Accurip- check yer overprints, go to the dialogue and check the spot colors and print size, hit print and go do something else.
