No. I think you'd have a bit of difficulty printing onto 1.5mm thick plastic with a conventional inkjet printer . What I meant was that the OHP transparency film has a glossy surface and this tends to reflect any incident light coming from the car's interior. You don't need a rigid plastic screen to give any kind of support to the film but it would be nice to get the anti-reflective properties of the standard screen. If I could make the glossy side of the film anti-reflective then I wouldn't even bother with the rigid plastic idea at all. I hope this all makes sense .
