Re: SPE and alt update
"As long as those photopolymers are based on monomers like acrylamide etc., the "non-toxicity" seems at least questionable..." ______________________________________________________________ "maybe questionable... but having used the acids and other chemicals required for the etching of metal plates, I feel much better about just using water and UV light to produce a gravure plate. I'll never go back to copper for etchings. The delicate detail and smooth gradations of even tone I can achieve with polymer plates more than satisfies my aesthetic needs for my work, whether I'm etching from a line drawing or a continuous tone positive. susan" Agreed. Speaking of non-toxicity in the case of these photopolymers is simply a bit of an overstatement. As long as they're not polymerized (by light or heat exposure), they're highly reactive ... Martin
