Hi: >From what I have read the polymer plates need a screen.
There is a very good web site about photopolymer plates at http://axp.psl.ku.dk/~ross/Ph_grav.html This source of screens is recommended: Hellas Grafisk ApS Islandsgade 28-30 DK-4690 Haslev Phone: (+45) 56 31 30 30 Fax: (+45) 56 31 70 30 Though I think I will try and find a North American distributor. I suspect the litho plates will need a screen. We're going to try some without any first. I think an easy way of producing a "low budget" screened image is to print out the image with a laserprinter an acetate. The laser printer makes its own "screen" I've seen gum-bichromate prints done this way. Its sort of a failsafe way of doing this. By the way - if this is becoming too much of a alt-photo discussion we can move it to the alt-photo list :) Gord On Tue, 25 Sep 2001, Colin Talcroft wrote: > > Still interested to hear if anyone knows what kind of > tonal range the oven cleaner method allows.
