So we bought a new machine a few months back to replace our old Epson 9700, it was an Epson 9890. It started out giving us issues with film sizing... film to film, say color #3 film is slightly smaller than #1, #2, & #4, etc... It was always random, some jobs were fine, others were not. And sometimes it would be a warp, where the top left side of the film seemed stretched out, but the other 3 corners would register, sometimes a whole side would be off. Well we fixed that issue by adjusting our print settings to 'printer manages color' & setting it to 'Premium Luster Photo Paper (260) at 4(0.1mm) thickness. Since then our films have been lining up film to film in every case. BUT they are approximately 1/16" to 1/8" smaller than sizing in photoshop. So an 18x24" poster in most cases prints to film with the distance between the crop marks coming out to approx: 17.9375x23.875"
Anyone have some settings advice? What are you using to get accurate film results on your machine? Its funny, we never had an issue on our 9700, and I carried over the settings we were using on that to the new machine originally. But the 9890 now has a motorized roll feeder, I get the feeling that may have something to do with it? Needing to calibrate things or tweak settings that possibly could effect its feeding speed and tension.
We're using Fixxons Waterproof 4 mil film by the way.
