Risograph @ Lab

Risograph is a brand of digital duplicators manufactured by the Riso Kagaku Corporation, that are designed mainly for high-volume photocopying and printing. It was released in Japan in 1980. The RISOGRAPH is a stencil printing style digital duplicator. It works by piercing a printing stencil plate with holes and passing ink through the holes to transfer an image onto paper. Due to working with vegetable based ink and organic based master, large-volume printing with less power consumption than e.g. off set, printing with the risograph is environmentally considerate.

...
generally after your printing process: with a soft tissue/ cloth and some water, clean residue at the machine
during the process: if necessary, the roll at the paper feeder must be cleaned carefully with a damp cloth to avoid ink abrasion on subsequent paper
