Terminology

Aquagraph
A monoprint made by painting with a water medium on a metal, glass, or plastic plate and pulling one print from that plate. Additional colors can be printed by aligning the paper to the plate design.

Aquarelle
The technique of drawing or painting with transparent watercolor, or a piece of work made this way. French for “watercolor.”

Aquatint
An intaglio, etching, and tonal printing process in which a porous ground allows acid to penetrate to form a network of small dots in the plate, as well as the prints made by this process. Aquatints often resemble wash drawings. Any pure whites are stopped out entirely before etching begins, then the palest tints are bitten and stopped out, and so on as in etching. This process is repeated 20 to 30 times until the darkest tones (deepest recesses in the plate) are reached.

Art Conservation
Preservation from loss, damage, or neglect, stabilizing chemically and structurally, sustaining the survival of objects as long as possible in what is closest to their original form. The application of science to the examination and treatment of objects, and to the study of the environments in which they are placed — used, transported, and stored.

Art Deco
An art movement involving a mix of modern decorative art styles, largely of the 1920s and 1930s, whose main characteristics were derived from various avant-garde painting styles of the early twentieth century.

Artist’s Proof
One of a small group of prints set aside from an edition for an artist’s use; a number of printer’s proofs are sometimes also done for a printer’s use. An artist’s proof is typically one of the first proofs from a limited edition of prints, for the artist’s own copyright use, and marked as an A.P., and not numbered. Artist’s proofs generally draw a higher price than other impressions. The equivalent in French is épreuve d’artiste, abbreviated E.A.

Art Movement
An artistic style or tendency seen in the intentions or works of a number of artists, because there is a striking similarity among the techniques, philosophy or goals they have embraced, or in the attitudes which they espouse in a (more or less) organized effort. Art movements have each thrived for a limited time — measured in a few months, years or decades.
