Some time ago we bought some professional UV-lamps to burn screens. The problem was, that we needed to find a way to fix them to the ceiling, so we postponed using them from week to week. Today we finally went to work and already burned some test-screens. Burn-time went down from 12 minutes to about 1 minute, pretty impressive! I got the screens for my delta quads roller derby poster ready, so printing might start this weekend!
