Expansion

Etching is an intaglio printmaking technique that creates thin, fluid lines whose effects can vary from graceful and serpentine to tight and scratchy. An etching needle, a fine-pointed tool, is used to draw on a metal plate that has been coated with a thin layer of waxy ground, making an easy surface to draw though. When the plate is placed in acid, the ground protects the areas it still covers, while the drawn lines expose the plate and are incised, or “bitten,” by the acid. After removing the coating, the plate is inked, filling only the incised lines. Damp paper is placed on the plate and run through a press, forcing the paper into the incised lines to pick up the ink.
