I had my first experience of solar etching this weekend. Here's the result:
Untitled. 2013. Print on paper. |
The process is like sunbaking. You cover the parts on a photopolymer plate that you don't want to burn with absolutely anything at all. Those parts become the raised surface of the plate, from which you can print hundreds of copies.
I drew my Balinese guardian onto a transparent plastic sheet with a greasy crayon, clamped that to the plate, then put them in the sun for 45 seconds. After a couple of minutes of washing and drying I was able to print. That simple!
