Giovanni Benedetto Castiglione was an Italian Baroque painter, printmaker and draftsman, of the Genoese school. He is best known now for his etchings, and as the inventor of the printmaking technique of monotyping. He was known as Il Grechetto in Italy and in France as Le Benédette.

Printmaking is the process of creating artworks by printing, normally on paper, but also on fabric, wood, metal, and other surfaces. "Traditional printmaking" normally covers only the process of creating prints using a hand processed technique, rather than a photographic reproduction of a visual artwork which would be printed using an electronic machine ; however, there is some cross-over between traditional and digital printmaking, including risograph.
