Sam Francis monotypes are his most sought after graphic works. Both painterly and graphic, monotypes are a hybrid of printmaking and painting, that embraces uniqueness over multiplicity; each impression is entirely unique. According to the Sam Francis Foundation, monotypes hold the same regard as unique works. Monotypes are created by applying ink, paint, or dry pigments on a smooth surface. Before the ink or paper dries, a paper is applied on top with firm pressure. The result is a print made from the impression that cannot be recreated. Sam Francis preferred monotypes as they were considered the most painterly method in printmaking. He created unique results by constantly altering the pressure, technique and paints he used in the process. These rare and exceptional works are wonderfully layered and colorful and demonstrate the gestural and spontaneous style of art which Francis is known for.
