The acid plate etching process involves cutting a metal plate and covering the plate in a layer of wax. The image required is then scratched into the wax using a different depth to achieve different textures and shading. The plate is then dipped in a bath of acid. The acid will eat into the metal plate where it comes into contact with it but will not be affected where it is still covered in wax and the time for dipping is carefully calculated to ensure that exactly the right texture is achieved. Once complete the plate is rinsed and the wax removed. Ink is rubbed onto the plate and then the plate is placed on paper that has been soaked in water and then put through a printing press to produce each unique print.
