A one-of-a-kind xerograph is the result of an image or object that is moved while the photocopy machine is in motion so that a new--impossible-to-replicate--image is produced. The resultant image is, then, not a copy of the original image or object but an original in its own right. This rigorous process of exploiting the photocopier"s potential was developed by the quixotic Italian artist and designer Bruno Munari in the series Quaderni di Design (1977), and is reproduced here--flying in the face of digital technology--for a new generation of xerography enthusiasts. Every phase of the copy-making process, from reading limits to toner concentration has been systematically tested (to exacting 1970s standards) by Munari. The result is a witty series of samples that exhaustively detail every imaginable potential of the machine, some of which are quite unexpected.
