Print Making with Artist and Teacher from Geelong College, Greg Smith.
"The print is called a ‘Solar Plate’ etching. The image is etched into a shallow UV-senstive film on the surface of the plate.
The etching can be made from almost any source – drawing, photography etc. In this case, I made the etching from a drawing that I made in the Musee d’Orsay in Paris. The drawing is transferred onto acetate, then the plate is exposed to light with the acetate clamped between the plate and the light. The UV hardens the plate where the light penetrates, leaving the drawing etched at different levels, depending on the tone. Once exposed, the plate is simply washed in mildly soapy water to wash out the etch.
The plate can then be inked, wiped back – the ink is held to differing degrees of tone depending on the depth of the etch - and printed on the press."
