My new screen exposure setup.
This was last weekend's big project. I've been pussyfooting around for four years without an easy way to burn screens, finally taking steps to remedy that. I don't have space to devote to a vacuum table or light box setup large enough to be worthwhile, so I figured out how to add another function to an already multi-use space.
This is in my workshop shed, which already provides bike, tool and garden supply storage and has my screenprint tables. I was able to hang this fixture on chains from the rafters so that it's 3 feet over the table for exposing screens, then gets raised up so I don't bang my head when I print. I wish it was on pulleys, but for now two carabiners do the trick. It didn't cost much - $12 for the fixture, $7 for the chain and hardware and $30 for two bulbs. Right now they are normal blacklight bulbs, which I hope to replace with unfiltered ones for faster exposure when I find a good source. For eye safety I rigged it up so I can turn it on and off from the other side of the door.
I coat and dry the screen, then spread out some matte black cloth on the table, put the screen down, weight it with bricks to keep it steady. Top with positives and a piece of glass.
It's working pretty well, I'm still tweaking timing and washout methods but overall I am quite happy. I'm also thinking about getting normal florescent tubes to swap out for when I'm printing, as there's never enough light in that space.
