One of these techniques is etching, more specifically, photo etching (used by Edwards Bernstein). In this process, the high contrast film is the matrix and the plate is the transferring base. The plate is covered with a light sensitive emulsion, and placed upside down on the plate. The emulsion is then exposed to a light source that uses ultraviolet rays. The image is allowed to harden on the plate, and then be washed, so that the flaky pieces will wash away. What ever is left now becomes the image. The plate is etched and follows the original printmaking process.…
