Acid Etching
Acid etching, from the German word meaning “to eat,�is cutting into a surface of a material using acid. The method of etching on metal can be a chemical process using acid, a photochemical process, or an electrochemical process. The basic technique for acid metal etching is to apply a resist to the areas of a metal plate, either to the whole plate or just to the areas that one wants to remain unaffected. The parts of the metal to be etched are either not covered or the resist material is scratched off from them using tools such as an etching needle and an echoppe.
The metal plate is then dipped in acid which eats away the exposed surface of the metal, creating lines. To make a print, the resist is cleared away and the surface inked. When the surface is wiped, the ink remains in the etched lines and can then be captured on paper when put through a specialized printing press. Varying line depth is accomplished by removing the plate periodically and covering the lines that have reached the desired depth with the resist material. This can also be done by applying acid to the plate directly rather than bathing it.

Precision Etching Metal Dimensions
Because of the many parameters involved in ***ermining etching tolerances, it is impossible to give a definite, absolute rule to cover all circumstances. Some of the more common variables which affect the etching tolerances are: type of metal being etched, size of panel, equipment being used, and yield required. For purposes of establishing some general rules of thumb, a tolerance |
