Risograph is a brand of digital duplicators manufactured by the Riso Kagaku Corporation,[1][2] that are designed mainly for high-volume photocopying and printing. It was released in Japan in 1980. It is sometimes called a printer-duplicator, as newer models can be used as a network printer as well as a stand-alone duplicator. When printing or copying many duplicates (generally more than 100) of the same content, it is typically far less expensive per page than a conventional photocopier, laser printer, or inkjet printer.
