THE ETCHING PROCESS

These etchings are produced on a copper plate. After the preliminary drawings are put together. The final drawing is then reproduced in reverse by hand. This is transfered on to the plate with a needle point after an acid-resist ground has been laid. The drawn plate is placed in an acid bath for a certain amount of time, depending on the weather and the age of the acid.

The acid bites into the exposed areas of copper thus creating a groove. This is placed on a hot plate and the inks are applied. The inks are then wiped off and the prepared plate is put through an etching press under a piece of etching paper that has been soaked and blotted. The end result is an original print which must be left to dry and be flattened for two days. It is then ready to be signed and editioned.
