Waterproof and adhere wide format print

Hello

i plan on printing with the epson 7880 along with regular stock paper with dimensions around 2’ x 3.5’ colored prints

going to adhere the paper to the underside of acrylic plexiglass, what is the best method to adhere the paper to the acrylic and water proof it

Just curious, but why do you want to “water proof” it

its going to be a LED back lit outdoor display

ideally i would like it to be all weather, rain sleet hail snow

@Coul was working on printing on a backlit plastic last Christmas. I never saw the final product but it was going well.

thats very similar to what im trying to do

From what I remember he bought the film from epson online. That’s about all I know.

thanks uglyknees

i know theres various ways to go about it, but just uncertain as to what is the best one currently
