- An intaglio etching and printing process in which areas of a metal plate are dusted with fine, acid-resistant particles such as powdered resin.
The uncovered areas are then bitten away by acid to create a granular surface that produces soft, tonal effects.
- An etching or engraving process focused on creating tonal variations rather than linear affects, which gives the appearance of a watercolor. It is often used in conjuction with line etching.
Aquatint is created by acid biting into a metal plate and involves putting granular resin over the plate, creating the design, and then immersing in acid.
Tonality is achieved by repeating the varnishing and immersing.
