I was using an 1800dpi stochastic screen for mine, along with a very basic curve. They did require a little bit of Na2 for contrast control, but not a lot. I worked with Peter Ellzey at Copygraphics at the time.

It’s just really hard to make tests over there because of lack of environmental controls. So after repeated tries, I finally gave up.
