An intaglio printmaking technique that creates thin, fluid lines. A pointed tool is used to draw on a metal plate that has been coated with a thin layer of wax. When the plate is placed in acid, the drawn lines are incised (or ‘bitten’) by the acid. The coating is removed and the incised lines are filled with ink. Damp paper is laid on top of the plate and run through a press that squashes them together and transfers the ink onto the paper.
