Etching is an old printing technique, using strong acid a design is cut into the unprotected parts of a metal surface to create an image template. Ink is rubbed into the areas created by the acid. The metal is then, with a piece of paper on top placed into a printing press and the image is transferred. The metal template can be used multiple times.
The art-teacher at the school where I work provided a course in etching and I asked if I could join it. He personally guided me thru the process which requires a multitude of steps. You can watch these steps in the video above. While working on this project between June and August, I also recording my progress on Twitter.
You can also add greyscale to an etching by covering parts of the metal and placing it back into the acid bath for a minute or so.
We did this four times.
It’s hard to estimate what the end result will be and I wasn’t entirely happy with the next series of prints. (This image is of the print before removing the wax dust, that’s why the metal looks dull.)
4th print, I felt that there was too little difference between the body and the background and the highlights on the scales were too bright.
