were printed on a clean zinc plate with oil paint or etching
ink and transfered to paper via an etching press. Some of
the prints have gone through the press a number of times,
each time adding more color.
use the monotyping process on a previously etched zinc plate.
Usually they go through the press twice: first painted with
color and secondly with the same plate cleaned and inked with
a stiff etching ink.
in printmaking each plate is assigned one color. In this suite
each plate carries a number of colors, each color printed
separately. Every print was made from the same three or four
plates, some of them carrying as many as eight colors.
This is accomplished
by using a square plate which can be rotated 90 degrees on
the press, carrying a different color with each rotation.
Potentially four colors could be printed from each plate without
one color canceling another out.
Like pure painting,
with this method a print is made with no pre-planning except
for a color idea. The print is simply started from plates
that also were etched with no pre-design toward a final print,
but which evolve as the process is executed.
