Leptání

Leptání is a Czech term that translates to etching in English. It refers to a printmaking technique that uses acid to create an image on a metal plate. The process begins with preparing a metal plate, typically copper or zinc, which is then covered with a protective ground, usually a wax-based substance. An artist then uses a sharp tool to scratch through the ground, exposing the metal where they want the ink to adhere.

Once the design is drawn, the plate is immersed in an acid bath. The acid "bites" into the exposed metal, creating recessed lines or areas. The longer the plate is left in the acid, the deeper the etch, which will hold more ink and appear darker in the final print. After the etching process, the ground is removed, and the plate is inked. The ink fills the recessed areas created by the acid.

A piece of paper is then placed on the inked plate, and the plate and paper are passed through a printing press. The pressure of the press forces the paper into the etched lines, transferring the ink and creating the print. This technique allows for a wide range of tonal variations and fine detail, depending on the artist's control over the etching process and the type of acid used. Leptání is a versatile medium used by artists for centuries to create original artworks.
