The Etching Technique of Francisco Goya

The video tutorial explains the Intaglio printing technique, focusing on etching and aquatint processes. It begins with an introduction to Intaglio, highlighting its importance in European art. The etching process involves heating a copper plate, applying a waxy ground, and using an etching needle to create designs. The plate is then immersed in acid to etch the design into the metal. Inking and printing follow, where ink is applied to the etched grooves, and the plate is pressed onto paper. The aquatint technique is introduced to add tonal effects, using powdered rosin and acid to create a grainy surface that holds ink.

Explain how the final print differs from the original etching on the plate.

What is the purpose of dusting the plate with powdered rosin during the aquatint process?
