risograph
OAB Definition
the Risograph duplicator is a Japanese copy machine that varies from western xerographic technologies which rely on electrostatically charged toner particles. In contemporary practice, artists and self-publishers embrace risograph as an efficient method to produce vibrant posters, zines, and other print-based output. Essentially, the machine is a compact silkscreen unit that exposes a screen from a digital file or scanned hard copy and prints layers of soy-based inks.
