I have had the Print Gocco System (Instant Etch) for about three
years. It works well for reproducing artwork that would be tedious to
draw directly on metal. The screens are reusable, so that you can
make more than one copy. For my purposes, it’s a great way to make
patterned sheets of metal. I usually make a photocopy “collage” of
high contrast patterns such as stripes, checks, dots, etc. and end up
with a sheet of patterned silver. The last time I etched, I put
patterns on the front and back of the sheet (dry the resist on the
first side before you print the reverse). The gave me maximum use of
the metal. After cutting out my main piece, the scraps are usuable on
one side or the other for something else. You have to cover the back
anyway, and I hate covering the back with a solid resist.
I am also now ready to try a new photostencil called PhotoEZ. Its an
offshoot of the glass etch/sandblasting/photo stencil products. I
have the product, but have yet to see if I can force either a resist
or a glass etching cream through the stencil.
Lastly, has anyone tried to etch an inexspensive quartz or chalcedony
type cabochon with a glass etching cream yet ? I’ll try it, but was
wondering if anyone else has done it already.
