Digital BW, The Print

Hi Martin,

From the last link I posted:

"A Photogravure print is composed of microscopic, irregular-shaped particles
of raised ink of varying widths, surrounding the white (or light) spots,
which result from the protection given by the rosin to the metal when the
plate is etched. As in an aquatint, the darker the portion, the smaller and
farther apart are the white spots."

I don't know how that is actually accomplished, but the print ends up being
basically similar to a halftone process in that it uses a single ink, and
the size of the ink "spots" and the amount if white space, to simulate
tonality.
