When I was in college we used heat presses. Nice flat prints on board always appealed to me. The last time I tried spray adhesive it was a disaster. Not long after using it my prints were curling at the edges. Maybe I was just using a poor quality adhesive. I'd like to know if people are having good success with spray on as well. I'm also wondering if there are any archival issues with using spray or dry mount tissue with a heat press...
