PHOTOGRAVURE

Update (August 21): I am looking for a way to translate my drawing style into a more tangible support than newsprint.  I thought that photogravure might directly transfer one of my drawings into an etching medium, if I drew on cotton vellum.  Mary helped me experiment with photogravure at Remarque/New Grounds Print Workshop in Albuquerque:


Various exposures on test plates
using the same pencil drawing


The UV exposure unit


Test plates with the "unit exposure"
listed on the back of them 
(higher number, longer time)


The pencil drawing on cotton vellum paper
(not darkened by the computer, as the image far above was),
which is placed on top of the plate,
drawing side face down,
closer to the copper plate


Washing the exposed plate
in 80 degree water,
to "develop" the image --
after washing, run cold water over the plate
to set the image

The procedure is to expose the plate twice.  One with the drawing on top of the plate.  A second time with a dot pattern on top of the plate.  Then wash the plate in water to develop it.

Afterwards, dry the plate, and let it sit in the sun for 30 minutes, to cure the image onto the plate.


The best tests were exposed to
24 and 22 units.
The "24 Weird" plate was washed less


Ultimately, washing the plate the conventional way, until there was no slippery sludge on the surfae, did not work.  It seemed to wash away a lot of extra emulsion, that destroyed the image.

The most successful print came from a plate that was washed quickly, only until the image showed up.

Perhaps the plates should be exposed to even more units, and washed more vigorously, to pick up all the light grey lines.
