Is "CPU" a word or is it an abbreviation?  Only kidding and not meant for
further protracted discussion.

I am not going to take sides on the "halftone" vs. "dithering" controversy;
but I will say that the back and forth over the question was informative
whatever position one takes in that it increases one's ability, at least, to
make clearer and better informed distinctions.  Hence the OT discussion was
not without merit.

Fair answer.  I think others still believe that the process is called
dithering, and that halftoning is something not used in digital printing.
I've been in the digital imaging industry for a while, so I don't read what
anyone else writes on the subject...except data sheets...so I'm going to go
buy some of those reference books and see how they describe it.  I do find
it fascinating that some people have adopted a, in my book, 'new' term for
'this'.  Kind of like changing the word CPU...
