I'm trying to print on Inkpress Backlight Film using an Epson 3880. When I print on the glossy side using the Glossy Photo Paper settings I get a smeary mess. I've done a lot of searches and it sounds like this should work. Any idea what I'm doing wrong?
Use matte side of the paper but with the image reversed since you'll be viewing from the glossy side. The key is to use matte black ink for the deepest black for the matte side.
