Riso Kagaku Corporation (理想科学工業株式会社, Risō Kagaku Kōgyō Kabushiki-gaisha) is a Japanese corporation which is the inventor, manufacturer, and distributor of the RISO Printer-Duplicator, a.k.a. Risograph. This device automatically creates a stencil-type master (from a paper original or digital file), thereby enabling it reproduce single-colour documents at high speed and low cost, in a machine that has a small footprint and a relatively low purchase price.

The firm was established in Tokyo, Japan, where it continues to maintain its headquarters today. With sales in over 150 countries, Riso is a billion-dollar company. The company maintains a foundation that donates equipment around the world primarily to educational institutions.

In Japanese, 'Riso' means 'ideal' and the word 'Kagaku' means 'science.'

Noboru Hayama, the company's founder, started his business by mixing inks at his kitchen sink just after World War II, and in 1946 established a mimeograph printing company, whose first product was its signature duplicator.[3] Over the next few years, Mr. Hayama expanded his company to the area of manufactured emulsion inks, stencil masters, and other duplicating products.

In January 2011, Riso Kagaku Corporation was noted to manufacture the world's fastest full color cut-sheet inkjet printers in its price category. The ComColor inkjet printer family is the third generation of production inkjet printers following the HC5500 and HC5000 product lines. ComColor printers print at speeds up to 160 letter-sized pages per minute (GD series, as noted in May 2021), while consuming less than 1/2 the electricity of traditional toner-based (electrophotographic) printers and copiers. These are office-sized machines.

The high-speed sheet-fed colour inkjet Riso Valezus T2100 prints at 320 double-sized pages (A4/letter size) per minute. This is a machine for a small-to-medium-sized print-shop operation.

Sponsorships[edit]

The company sponsors the J.League football club Kashima Antlers with the RISO logo appearing on the back of the club's shirt.
