Engraving is a printmaking technique that involves incising a design onto a hard surface, traditionally a metal plate. The incised lines hold ink, which is transferred to paper under pressure, creating detailed images. This method has been used for centuries to produce illustrations, currency, and fine art. The process of engraving requires precision and skill, as artists use specialized tools called burins to carve intricate patterns. Famous engravers like Albrecht Dürer have contributed significantly to the art form, showcasing its potential for both artistic expression and reproduction of images.
