Mezzotint is a printmaking process of the intaglio family, technically a drypoint method. It was the first tonal method to be used, enabling half-tones to be produced without using line- or dot-based techniques like hatching, cross-hatching or stipple. ...
An intaglio process invented around 1650 that allows the printing of rich tonal areas of black and grey. The mezzotint process begins by texturing a metal plate in such a way that it will hold a great deal of ink and print a solid black field. This is done with a tool called a "rocker. ...
A method of engraving on copper or steel by burnishing or scraping away a uniformly roughened surface, also called "brush" or "Florentine" finish; derived "middle + color"; compare stipple, tesselate, reticulate. Also, a print produced from a plate made by this method. ...
An intaglio process in which the surface of the plate is scored by a spur like"rocker" so that it is completely roughened. The plate is then smoothed in areas to produce modulated tones of light and dark values.
Method of copper or steel engraving in tone. A Dutch officer, Ludwig von Siegen, is given credit for the invention of mezzotint c. 1640. The process then came into prominence in England early in the 18th century. ...
A form of INTAGLIO printing whereby the whole PLATE is roughened to produce a burr which will carry INK. The artist then scrapes down the burr in proportion to the degree of lightness required. Very few IMPRESSIONS can be taken from this type of delicate PLATE before it becomes damaged.
The plate is roughened uniformly with a tool called a rocker, after which the burr in certain areas is burnished (rubbed) down so it will hold less ink.
(mezzo = half + tinta = tone), a reverse engraving process used on a copper or steel plate to produce illustrations in relief with effects of light and shadow. The surface of a master plate is roughened with a tool called a rocker so that if inked, it will print solid black. ...
