no. of stops in pt/pd and gum etc.



Hi all,
I came across an article by an unnamed author :) that said "gum requires a density of 0.7 or 2 stops and pd of 2.0 or 7 stops. " These seem low to me in my experience with either, but I was wondering in average practice how many stops you all have found with either process? I thought pt/pd could print 10 stops, was I wrong?
