As someone once said, "that escalated quickly".
I'm a little afraid to add my two cents, but I read this thread carefully hoping for a clear answer, which I almost, but not quite, got.
We buy our wide format prints from a few different wholesale suppliers. And one of our weak spots is direct prints on aluminum composite panels. Whether it's for 24" x 18" lawn signs, job site signs or exterior signs of any kind, they look great (if they arrive without scratches) but often don't even last until we get them out the door. And this is from any one of five different printers.
The prints are too easily scratched.
We have a film laminator (from when we used to print our own wide format) and would rather apply a film laminate than watch these prints get ruined.
Is there a particular film or type of film recommended for this application?
