Does anyone know of any sort of duratrans-like/backlit film for the Epson 7600? I've got a series of digital images I'd like to mount on top of custom-built lightboxes for an undergrad. exhibition I'm currently working on, but have beeen unable to find any suitable surface I can make the prints on. They're going to be quite large (approx. 20x40), and thus I'd prefer to print them myself on my photo program's 7600 as opposed to having to send out to have them made. I'd appreciate it if anyone either has any experience in this or if y'all know of any good media to use. Thanks!
