[Alt-photo] Re: Stochastic screening in Gum

What is your goal Peter?
I use both technics, gumprinting and polymer photo gravure and don't see the
advantage.
I actually think the gum print will be more grainy.

I think Steven Livik may have done, it's in his manual IIRC.

generates diffuse UV light so I think that may not be as effective as a more
point sourced arc type UV lamp.
