Ars Combinatoria is an exploration of the graphic possibilities of a single piece of wood type—a thirty pica Clarendon R—and a restricted set of operations—positive and negative auto-pressure printing with only one inked impression. This technique enables the top of the wood type to interact with the bottom and itself. With æsthetic and technical constraints there are eighteen prints, twelve of which are displayed here. The suite of prints comes in an elegant box with a small booklet—printed in three color offset lithography—explaining the process.
