    Another question though, possibly very stupid, so be gentle .

    I lustfully looked the picture of your setup, looks fabulous.

    But if the bulbs are at the top facing down onto the paper, how does your vacuum work??
    (I use a huge UV box at the Print Studio for polymer photogravures which has vacuum on top on a hinged lid, and bulbs below. The plates are placed face down facing the UV bulbs, and the top lid closed, then the vacuum seal is used to hold plate flush to glass).
    Yep, it really was a stupid question - have answered it myself...!

    Wouldn't it be simpler to either make a contact frame for the dimensions you want or have a piece of 1/4" glass cut and just use that? You could design a simple clamp (thinking plastic knobs plus fender washers) to hold the glass/neg/paper together.

    I just skimmed this post but why cant you use the light source that you do your polymer plates one? Thats what I would do.

    A couple of reasons - firstly the UV vacuum box is in a shared access print studio (intaglio, screen prints, linocuts, etc), rather than my own photographic studio, and the studio use policy and rules on chemicals in the shared space means it's a no-go. Secondly, it's lit by a single source, which others have suggested elsewhere might result in an uneven exposure? (This might not be the case, but as per reason 1, I haven't been able to find out)!
