Just in Time, or a Short History of Production, is a book printed by four different printers, spanning 100 years between the printers' dates of manufacture: Magenta (Stencil duplicator, 1880); Cyan (Spirit duplicator, 1923); Black (Laser printer, 1969); Yellow (Inkjet printer, 1976). With each printer delegated to printing one ink plate, this book's production emphasizes the nature of the printing process itself, as well as its historical context.
