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. As a method of printmaking, it is, along with engraving, the most important technique for old master prints, and remains in wide use today. In a number of modern variants such as microfabrication etching and photochemical milling it is a crucial technique in much modern technology, including circuit boards.In traditional pure etching, a metal (usually copper, zinc, steel or Aluminium) plate is covered with a waxy ground which is resistant to acid.The acid “bites” into the metal (it dissolves part of the metal) where it is exposed, leaving behind lines sunk into the plate.The plate is then put through a high-pressure printing press together with a sheet of paper (often moistened to soften it). The paper picks up the ink from the etched lines, making a print.
The work on the plate can also be added to by repeating the whole process; this creates an etching which exists in more than one state.
