I've been making my positives with transparencies through an inkjet printer. I tape them all back together and it works. But i want to see what else is out there. Has anyone tried having kinkos print transparenies from file? Not from the photocopier. I want to know what the opacity is like. Can they do bigger than 8.5x11 so I don't have to tape them all back together? Cost? I'm looking to get out on the cheap side of things. And I don't want to mess with that oily paper mess either.
