Materials & Techniques
Etching occurs through a chemical reaction, and thus requires a metal plate to be prepared with an acid-resistant material called a ground. A design is drawn on the ground with an etching needle to expose the metal. When immersed in an acidic bath, exposed areas of the plate are dissolved in a process called biting. After removing the ground, ink is applied to the crevasses and wiped from the plate's smooth areas.
