[Alt-photo] Stochastic screening in Gum

[Peter Friedrichsen]

Has anyone applied a stochastic screen to gum printing? This is a 
half tone technique that uses dot frequency to emulate 
color/greyscale. The smaller the dot size, the more photographic the 
rendition. My UV box generates diffuse UV light so I think that may 
not be as effective as a more point sourced arc type UV lamp.

Has anyone done anything like this before? I was wondering what the 
minimum dot size that could be realized from a contact negative?
