I use adhesive backed pressure sensitive photo paper or poly. Check with your supplier. Check out lexjet.com they should have some there.
What are you guys using to mount photo paper to foamcore?
Three weeks ago I printed 24 X 36 photo ads, used super 77 to glue them to the 1" foam core... They are bubbling pretty bad!
Is there a reason not to just print onto matte vinyl and mount that to the Foamcore?
