    is an acrylic polyurethane spray clear-coat an acceptable way to finish UV print?
    mathews acrylic polyurethane, to be precise, or would solvents break-down the ink?

    I would attempt a sample, but I only have a latex printer. This finished print was provided by a 3rd party using a UV printer on 2mm white transparency film/poster, but I don't want to fall-back on finger pointing when the first person to walk by this thing clips it with their purse and puts a white line thru the image.

    My other option would be a water-based liquid laminate, but it would require hand-rolling that usually leaves a less-than perfect finish.

    I would probably give it a dry coat or two. Then, you could spray it with as much as you want. I do it quite often.

    We spray over our UV prints all the time. We use Grip Guard products. Like Gino said, you have to put a light coat on first, you bury the print in clear the solvents will affect the print. Have not tried with Matthews but assume it will work.

    hell yeah, i'll give it a go. same way I clearcoat my foil stamped photopolymer ADAs. too heavy and it starts to break down the ink. dry/light coat it a couple of times before a finish coat, comes out pristine.
    Thanks for the tips!
