The zinc affected by the lines of the drawing proof would be coated with hygroscopic salts. Bathing the plate in acetic acid resulted in the dissolution of the salts, the asphalt varnish protecting the remaining surfaces of the plate. Then the printer would coat the plate with a colored lacquer varnish called fuchsine, dried, dipped in benzene ...
Normally, copper or in recent times zinc sheets, called plates, are used as a surface or matrix, and the incisions are created by etching, engraving, drypoint, aquatint or mezzotint, often in combination. [3] Collagraphs may also be printed as intaglio plates. [4]
Goya, No. 32 of Los Caprichos (1799, Por que fue sensible).This is a fairly rare example of a print entirely in aquatint. [5]In intaglio printmaking techniques such as engraving and etching, the artist makes marks into the surface of the plate (in the case of aquatint, a copper or zinc plate) that are capable of holding ink.
Other terms often used for printed engravings are copper engraving, copper-plate engraving or line engraving. Steel engraving is the same technique, on steel or steel-faced plates, and was mostly used for banknotes, illustrations for books, magazines and reproductive prints, letterheads and similar uses from about 1790 to the early 20th century, when the technique became less popular, except ...
Lupton was mainly responsible for the introduction of steel for mezzotint engraving. Hoping to find a more durable substitute for copper, he made experiments on nickel plates, the Chinese alloy called tutenag (an alloy of copper, zinc, and nickel), and steel, and, deciding upon the latter, used it for a successful portrait of Munden the actor, after Clint.
The plate is then completely submerged in a solution that eats away at the exposed metal. ferric chloride may be used for etching copper or zinc plates, whereas nitric acid may be used for etching zinc or steel plates. Typical solutions are 1 part FeCl 3 to 1 part water and 1 part nitric to 3 parts water. The strength of the acid determines the ...
