Risography is a technique where you use a duplicating machine to print colours separately, layer by layer. The result is somewhat reminiscent of screen printing. Risography uses semi-transparent inks based on vegetable oil (soy or rice). Due to the technology, each print is slightly different, which makes each print unique. size : A6 (105 x 148 mm)
