When hand-colouring with dyes, a weak solution of dye in water is preferred, and colours are often built up with repeated washes rather than being applied all at once. The approach is to stain or dye the print rather than to paint it, as too much paint will obscure photographic details. Blotting paper is used to control the amount of dye on the ...
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.
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 speed of the etching process. The etching process is known as biting (see also spit ...
A print made using the Albertype process 1920 hand-colored Albertype of Glacier National Park in the United States. An Albertype is a picture printed from a type of gelatine-coated plate produced by means of a photographic negative. [1]
Later that century, for decorative uses "poster paint" (as it is known in the U.S.), was mass-produced, based on the much cheaper dextrin binder. It was sold in cans or as a powder to be mixed with water. The dextrin replaced older paint types based on hide glue or size. During the twentieth century, gouache began to be specially manufactured ...
Viscosity printing is a multi-color printmaking technique that incorporates principles of relief printing and intaglio printing. It was pioneered by Stanley William Hayter.. The process uses the principle of viscosity to print multiple colors of ink from a single plate, rather than relying upon multiple plates for color separation.
A larger burr, formed by a steep angle of the tool, will hold a lot of ink, producing a characteristically soft, dense line that differentiates drypoint from other intaglio methods such as etching or engraving which produce a smooth, hard-edged line. The size or characteristics of the burr usually depend not on how much pressure is applied, but ...
One of the qualities for which artists value casein paint is that unlike gouache, it dries to an even consistency, making it ideal for murals. Also, it can visually resemble oil painting more than most other water-based paints, and works well as an underpainting. Casein paint loses its solubility with time and exposure and becomes water-resistant.
