Risograph.

How to recognize it.

1. Overprinted inks
2. Visible registration shifts
3. Grainy tonal screens

Context & origins.

The Risograph is a stencil-based printer that makes a master stencil and prints from it within one machine, lowering printing costs. It was developed in the 1980s by the Japanese company Riso Kagaku, which Noboru Hayama founded in 1946. Although artists and designers around the world have adopted it for its analogue character, including the scratches and small variations that make each print distinct, most of its use in Japan remains low-cost printing for schools, hospitals and government offices.
