Final answer:
The statement that etching is performed by immersion in an acid bath is true. Etching involves scratching a protected metal plate and immersing it in acid to create etched channels that hold ink, which is then transferred to paper.
Step-by-step explanation:
The statement regarding etching being performed by immersion is true. The technique of etching, used in both Etched Printing and Aquatint, involves covering a metal plate with a wax-based or acid-resistant layer. The artist then scratches an image into this layer to expose the metal underneath. Once the drawing is complete, the plate is submerged in an acid bath, which etches away the uncovered metal areas. After etching, the acid is rinsed off, and the remaining protective layer is removed. The depth of the etch, correlating with the amount of time the plate is in the acid, affects the tonal quality of the final print, as seen in the works of Francisco Goya. When ink is applied to the plate and then wiped clean, ink remains only in the etched channels, which transfers to paper under the pressure of a press, creating the print.
Intaglio Printing also involves etching but typically refers to the broader category that includes various techniques such as engraving and drypoint alongside etching and aquatint.
