1. I was printing last night, I had burned the screen, washed it out, and let it dry. Everything looked good I taped up the sides, started to print, the first 5 or so went well, then the emulsion on the screen started to stick to the paper. So when I lifted the screen some of the edges of emulsion were sticking to the paper and pulling off. It started in one area which luckily I was able to fix with tape, but then other areas started to do the same thing. They would bubble a little then start to get tacky and stick to the paper.
Any thoughts? Bad emulsion? I had to lengthen my exposure time because the screen kept washing out.
2. Glass for an exposure box. Right now I have a temporary light box consisting of two 500 watt work lights set in the bottom of a large tupperware box, which I set a piece of glass on, then my transparencies, then my screen, then some weight. And I have broken about 3 pieces of glass due to the weight I put on (which isn't much, but I want enough to keep the transparencies and the screen tight).
Where can I get a thick piece of glass that doesn't have any UV coating at a reasonable price?
