Intaglio printing is a printmaking technique where an image is incised into a surface, typically a metal plate. The incised areas hold ink, while the raised surfaces remain ink-free. This method allows for fine details and rich textures, making it popular for creating high-quality prints, illustrations, and banknotes. The process involves several steps, including engraving or etching the design onto the plate, applying ink, and then pressing the plate onto paper. The pressure transfers the ink from the incised lines to the paper, resulting in a clear and detailed image. Intaglio printing is known for its durability and ability to produce multiple copies.
