Intaglio printing is the opposite of relief printing, in that the printing is done from ink that is below the surface of the plate. The design is cut, scratched, or etched into the printing surface or plate, which can be copper, zinc, aluminum, magnesium, plastics, or even coated paper.
So, what is a dry point print?
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.
What is the process of etching?
Etching is traditionally the process of using strong acid or mordant to cut into the unprotected parts of a metal surface to create a design in intaglio (incised) in the metal. In modern manufacturing, other chemicals may be used on other types of material.
What is an etching and aquatint?
Like etching, aquatint is an intaglio printmaking technique, but is used to create tonal effects rather than lines. Intaglio refers to printing and printmaking techniques in which the image is incised into a surface, and the incised line or sunken area holds the ink.
