The risograph is a stencil-based duplicating machine that bridges screenprinting and photocopying. It prints one color at a time, building images through layered passes that produce a distinctive grain and tonal variation.

The process uses thin paper stencils, called masters, wrapped around a rotating drum to transfer soy-based ink onto paper. These masters function as the image matrix, linking risograph printing to long-standing printmaking traditions. Designed for repetition, the machine is well suited to larger print runs and remains valued for its sustainability, material character, and connection to the history of mechanical reproduction.
