UV exposure boxes

[Andrew O'Neill]

I have both a BLB exposure table from a screen printing supplier, and a 1000W halogen vacuum table I picked up from a retired screen printer. I use the BLB for making my Kallitypes, and the halogen table for my carbon transfer prints. You could easily use a contact printing frame, laying it face down. I don't bother with one. Instead, the negative is placed directly on the glass with sensitised material on top. A sheet of 1/4" plate glass over top, keeps everything flat and in tight contact. Been doing it this way for about 10 years.

The BLs are cheaper than the BLBs -- and might be a tad faster if more blue light can had from the unfiltered BLs.

Anyone used arc lamp sources from the offset printing world? I might get access to one.
