UltraVision Window Perf – UV is a perforated white gloss calendared graphic window film with a black adhesive backside, a paper backer and a unique additional center release liner. The release liner catches the ink while printing; preventing the ink from clogging the perforated holes. It is ideally used for exterior mounted window advertisements, in store, building windows or on vehicle windows. UltraVision UV has a specified open area (ie: 60/40: 40%) for optimal two-way viewing and can be printed on the front, non-adhesive side with solvent, eco-solvent and UV inks. For best installation results, an edge sealer should be used to help prevent the edges lifting after installation.
