Drypoint is a printmaking technique of the intaglio family, in which an image is incised into a plate (or "matrix") with a hard-pointed "needle" of sharp metal or diamond point. In principle, the method is practically identical to engraving .
Much greater pressure is then needed to force the paper into the channels containing the ink, so a high-pressure press is normally needed. Intaglio techniques include engraving, etching, and drypoint. In the planographic family of printing, the entire surface of the matrix is flat, and some areas are treated to create the print image.

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 ...
Drypoint and etching were also German inventions of the fifteenth century, probably by the Housebook Master and Daniel Hopfer respectively. [14] [15] In the 15th century, woodcut and engraving served to produce both religious and secular imagery. One of the most popular secular uses of engraver's art was in the production of playing cards, a ...
Etching soon came to challenge engraving as the most popular printmaking medium. Its great advantage was that, unlike engraving which requires special skill in metalworking, etching is relatively easy to learn for an artist trained in drawing. Etching prints are generally linear and often contain fine detail and contours.
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.
Detail of an etching of 1841 with surface tone on the structure at right, and its shadow (the whole print).. In printmaking, surface tone, or surface-tone, [1] is produced by deliberately or accidentally not wiping all the ink off the surface of the printing plate, so that parts of the image have a light tone from the film of ink left.
The term "crystallographic etching" is synonymous with "anisotropic etching along crystal planes". However, for some non-crystal materials like glass, there are unconventional ways to etch in an anisotropic manner. [2] The authors employ multistream laminar flow that contains etching non-etching solutions to fabricate a glass groove.
