Effect
Risograph
Risograph print layers with ink colours, misregistration and grain.
Riso Kagaku began as a mimeograph business in Tokyo in 1946. In 1980 it launched the RISOGRAPH, an automatic stencil duplicator that printed high volumes with emulsion inks at low cost. Schools, offices and later independent publishers adopted the machines.
Artists love Risograph for its spot colours, visible ink texture and casual misregistration between layers. This effect stages those print behaviours: limited inks, grain and the slight offset that makes a poster feel pulled by hand.
