There are several types of printmaking processes described in the document. Relief printing involves cutting away areas of the matrix so that only the remaining parts carry ink. Intaglio is the opposite, where the cut or etched areas hold the ink. Engraving uses a burin tool to cut into metal plates while etching involves using acid to bite lines drawn with a resist. Aquatint uses acid to create tonal areas and drypoint creates fine lines that wear down over multiple prints. Lithography does not require cutting, as drawings are made directly on stone or metal plates using waxy materials.
