Rollo Press is a small shop in Zurich, Switzerland that is based around a single RISO machine. We run a similar RISO at MYP. It’s basically a digital mimeograph or stencil machine. Unique in that unlike most digital printers, these use ink, not toner. These are used by schools, churches and non-profits all over the world to produce low quality 2-color newsletters and collateral. They’re also secretly used by lots of copy shops who tell their customers the job was put on press hoping the customer won’t pick up on the lower quality. That said, in the right hands with the right paper the results can be wonderful and carry an almost hand-pulled quality.
