[alt-photo] Light sources for polymer gravure

[e-mail henry.rattle]

Hello All,

Hope the quiet list is a mark of a productive summer!

I'm wanting to try polymer gravure, and have a small press and a nice
random-dot screen. The advice I see is that you need a point light source
for exposing the screen, but I only have my trusty five-tube BL diffused
exposure unit. What's the most economical way of getting a point source?
(don't say the sun - I live in England!) - or can you make a diffuse source
work?


Thanks for any ideas...

Best wishes

Henry
