Thanks again for info. Will now investigate the possibility of a homemade unit (well actually a made-for-me by a friend who is a joiner to trade!).
Another question though, possibly very stupid, so be gentle .
I lustfully looked the picture of your setup, looks fabulous. http://www.apug.org/gallery1/showima...imageuser=7447
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...!
