Re: cheap press for relief printing

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 :)
