paper backdrop cement ?

The problem with anything that is too wet (water or solvent based) is that it can ruin the inkjet printed page. You may have to go to a colour laser print, try different paper, and/or use a different glue. I used a photomounting glue last night (Christmas project) with no problems, but I was mounting a photo (thick photopaper) to foamcore. No real worries about wrinkling, or the glue soaking through.
