When the world was analog, stochastic may have been ahead of its
time. The limitations of film and plate inhibited its usage. Just
the physics of moving air molecules out between the film and plate
during drawdown had problems.
Now with digital plates, and better algorithms, stochastic's time may
have come. It may have a real future with hexachrome.

Just by pure chance, I happened to examine closely a recent New Yorker
magazine cover -- the October 10, 2005 issue.
I was quite surprised to see what I believe is stochastic printing.
See my web page for a gallery of images showing the cover, plus 2
portions
of it enlarged by about 500% (533.33%, to be exact). I outlined the
location
of the 2 enlarged portions in cyan in the Oct 10 magazine cover image.
My web page is at:

Strangely enough, the cover for the October 17 issue went back to
traditional 133 lpi halftone screening.
You can also view this more recent cover in the same web page, as
well as a
portion of it that I enlarged by the same ratio of 533.33%.
I have thrown away older New Yorker issues, so I am unable to
establish
whether stochastic is being used often in that magazine. In any
case, in
this instance it was limited to just the outside cover (the inside was
traditional 133 lpi halftone screening).
I find this use of FM screening in commercial magazines
interesting. I was
not aware of it having become so mainstream.
Anyone knows more about this trend?
Thank you.
