The Two Printmaking Processes Using Acid on Metal Plates

Etching and Engraving in Printmaking

Etching: In etching, an acid-resistant coating is applied to the plate, and lines are drawn into the coating. The plate is then submerged in an acid, which eats away at the exposed areas, creating grooves.

Engraving: In engraving, a metal tool called a burin is used to directly carve lines into the plate. Acid is sometimes used in the process to help create shading or to remove unwanted areas.

These two techniques are vital in creating intricate and detailed designs on metal plates for printmaking. The use of acid allows for precise removal of lines and shading, resulting in beautiful and intricate prints.
