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...
