Re: [pinhole-discussion] 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 :) 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.

Re: [pinhole-discussion] cheap press for relief printing
Yes, water-based inks work, but in that case you have to use a block made of something slightly absorbent that will hold the ink. In Japan, cherry wood was traditional (very expensive today), but any good wood will do. Surely there are other things that would be suitable, but metal plates (copper, brass, aluminum and zinc, among others can be used with oil-based inks), rubber, linoleum, etc. don't work with water-based inks. In my own work, I use combinations of wood and cardboard as the "plates" but use oil-based inks because the cardboard holds up better that way. Still interested to hear if anyone knows what kind of tonal range the oven cleaner method allows. Also interested in ongoing reports on the UV-sensitive resin emulsion developed in water that someone mentioned. I suspect these both require screens to get any kind of tonal range. Given the already highly contrasty nature of pinhole negtives in many cases, I wonder if this approach would yield good results very often, but who knows? For what it's worth, all the oil-based stuff can be done using relatively benign fuel oil (Japanese toyu--Ed help me if this is the wrong translation) as the solvent. It's not very volatile nor is it as carcinogenic as the stuff people often use (often benzene-rich). I'm very sensitive to solvents as well and this stuff is OK for me. The process is time-consuming, however. You either have the temperament for it or you don't. It can be tedious and messy--you're definitely right about that.

Re: [pinhole-discussion] cheap press for relief printing
I love printing off of photo plates, but what I couldn't get into the was the prep and cleanup time for each print. Inking the plate - and then cleaning it for the next print - was a time-consuming and messy job that involved the use of lots of solvents. I didn't like breathing that stuff for so long. Can you use water-based inks for this process? At 12:55 PM -0400 9/25/01, gina wrote: Dick Blick Art Supplies sells an old fashioned "wringer" type press for less than $200.

Its only limitation is the size-the wringers will only accomodate up to 11" width but the length is not limited.
