Re: Photopolymer Plate Options



Hi Chris,

I've never used a washout higher than 70-72 degrees with either types of plate, although I admit to extending the time very occasionally from 2 to anywhere up to 8mins. No scientific reasoning going on here, other than some plates and exposures you can just <feel> need a little longer washout. Naturally, I'm curious to try Jon's times of 35sec. I tend to let the plates sit still in the water for the first minute and then gently scrub them in a linear movement, rotating the plate 90 degrees each time. Rinse with cold water and immediately blot with sheets of newsprint to remove excess water.

I'm using an aquatint screen that I got through Dan Weldon.
