Need Help Window Perf keeps coming up

[DannySanti]

I am using some ultra-flex 70/30 window perf and I keep having issues where it wants to come up in the corners and also tries to flip back over on some of the short edges the whole way. I also put on edge tape. I am not sure if it's an ink issue oversaturation because I've done several with white edges and they seem to work really well but in any case I need to do edge to edge printing and I need something that will stick to the window. Any suggestions would be greatly appreciated.

Make sure the glass edges are super clean, use blades to get off anything you can't see. All the stuff they use to set the glass (silicone, lubricants, etc), you really can't get it all cleaned off tight to the edge without damaging the window seal, nor can you really see the residue. Trimming the perf or keeping edge tape back 1/8 inch or so from the seals usually does the trick, and it isn't really noticeable, or at least it's a lot better than watching it fail. If you're cut back from the edge and it's still lifting, you might need a better cleaning, or use a bead of primer around the perimeter too. Try some experimental pieces to see if that works.

Also, don't lay too quick after printing edge to edge, and don't go crazy on the saturation. Solvents from inks can penetrate through to the adhesive, make sure they're fully cured before laying.

That's about all I got.
