I won't repeat what I mentioned in my last post (which basically explains
halftoning) other than to say, Peter Davis's post regarding halftoning
is right on target and this is the way printing was (still is?) done
in the past. He is referring to printing and not computer halftoning.
Thus halftoning is the proper terminology in this context.
