Aquatint
Aquatint is an intaglio printmaking technique, a variant of etching.
In intaglio printmaking, the artist makes marks on the plate (in the case of aquatint, a copper or zinc plate) that are capable of holding ink. The inked plate is passed through a printing press together with a sheet of paper, resulting in a transfer of the ink to the paper. This can be repeated a number of times, depending on the particular technique.
