RE: Photogravure question

Mark,

There isn't any difference in the printing -- ink the plate, wipe the
plate with tarltan and (subsequenct finer buffing) newsprint, wet the
paper, run through the press. viola

a stochastic screen pre-exposure is the equivalent of the rosin
aquatint on copper.

Jack and others of great wisdom,

I can see how the proecesses of traditional photogravure and of
polymer plate
are different mechanically-how do they differ in terms of how the ink
actually gets laid down on the paper in the end and how does it look
different?

Second, can the stochastic screen or some sort of similar digital
screen
emulate the rosin dusting used in traditional photogravure?

Thanks in advance for raising my level of ignorance above that of a
cabbage.
