The desire that drives an artist to graphic work is perhaps partly the effort to capture the unique and indefinite nature of a drawing in a fixed and durable form. Another aspect of it is that the technical manipulations exercise energies in the artist that he does not use in the far less strenuous crafts of drawing and painting... the mysterious attraction that surrounded the invention of printing in the Middle Ages is still felt by anyone who takes up graphics seriously and performs every stage in the process wit hits own hands.
