When was aquatint invented

The first etch should be for a short period of time 30 seconds to 1 minute, with a wide variation depending on how light the lightest tones are meant to be.

A test piece may be made with etching times noted, as the strength of the etchant will vary. More than thirty minutes should produce a very dark area. Etching for many hours up to 24 will be as dark as etching for one hour, but the deep etch would produce raised ink on the paper. Contemporary printmakers often use spraypaint instead of a powder.

Rosin, from the pitch of pine trees, is the same material used by a violinist. Like etching, aquatint is an intaglio printmaking technique, but is used to create tonal effects rather than lines. The plate is then immersed in an acid bath , just like etching. The acid eats into the metal around the particles to produce a granular pattern of tiny indented rings. Technically a drypoint method. Mezzotint begins with a plate surface evenly indented with a rocker to produce a dark tone of ink.

It is smoothed and polished to carry less ink for a lighter shade. Aquatint begins with a smooth plate and areas are roughened to make them darker. Engraving is an intaglio printmaking process in which lines are cut into a metal plate in order to hold the ink.

In engraving, the plate can be made of copper or zinc. The metal plate is first polished to remove all scratches and imperfections from the surface so that only the intentional lines will be printed. Serigraphic printing consists of forcing an ink, by pressing with a squeegee, through the mesh of a netting screen stretched on a frame, onto the object to be printed. The Aquatint boxes are made with varnished plywood by Polymetal.

The action of the boxes are both based on the traditional hand driven paddle wheel which is driven by a handle on the outside. It has a wooden grill that slides out so the plate can be placed on it easily. Monoprinting is a form of printmaking that has lines or images that can only be made once , unlike most printmaking, which allows for multiple originals. Examples of standard printmaking techniques which can be used to make Mono-printing include lithography, woodcut, and etching. Aquatint is a form of etching, and drypoint is a form of engraving.

Etching uses acid to mark the plate; engraving does not. To print an intaglio plate, you fill the marks with ink and wipe the surface clean. The press pushes the paper into the inked lines. Lithography is a planographic printmaking process in which a design is drawn onto a flat stone or prepared metal plate, usually zinc or aluminum and affixed by means of a chemical reaction.

Acid aqua fortis is applied to the metal plate and bites channels around the resin droplets. The resulting microscopic reticulation will hold more or less ink, depending upon how long or how deeply the acid is allowed to penetrate the plate see a detail.

Tones ranging from light gray to velvety black can thus be printed. After starting his etchings with brittle but assertive lines, Goya proceeded to cloak them in haunting aquatint shadows. A graphic artist of astounding ingenuity and sensitivity, Goya created four great cycles of etchings to which aquatint contributed emotional depth: Los Caprichos Ives, Colta. Visiting The Met?
