Photo Etching Course
This course will cover preparing the plate, application of light sensitive film, making the image transparent for exposure, and exposing the image onto the plate. Any type of image can be used whether it is hand drawn, photocopied or a photograph. Inking, wiping, registration and printing will also be covered. Suitable for all levels.
What is Photo Etching?
Light sensitive polymer plates allow for photorealistic etchings. A photo-sensitive coating is applied to the plate by either the plate supplier or the artist. Light is projected onto the plate as a negative image to expose it. Photopolymer plates are either washed in hot water or under other chemicals according to the plate manufacturers’ instructions. Areas of the photo-etch image may be stopped-out before etching to exclude them from the final image on the plate, or removed or lightened by scraping and burnishing once the plate has been etched. Once the photo-etching process is complete, the plate can be worked further as a normal intaglio plate, using drypoint, further etching, engraving, etc. The final result is an intaglio plate, which is printed like any other.
