| Etching is a more involved process and takes a great deal of preparatory as well as printing time. In general, an acid resist covers a copper or zinc plate. The design is scratched through. The plate is placed in an acid bath where the incised lines and areas are bitten into the plate. This is repeated several times as the design progresses and desired areas are etched deeper. The plate is covered with printing ink and then wiped off leaving the ink in all depressed areas. It is then printed on dampened paper in a printing press. Lots of work and very rewarding.
Acrylic plates are also available. This avoids the use of acid baths. The plate is incised with etching tools and inked and printed as above. Each of the printing processes offers opportunity for unlimited expression. All the elements of design with personal interpretation can combine to create unending differentiation. Simple or complex, graphic arts are a viable and valuable form of creative articulation. |
