A risograph is a digital stencil duplicator primarily used for high-volume printing. It bridges the gap between traditional photocopying and offset lithography, offering a unique aesthetic characterized by vibrant colors and a textured, imperfect finish. The printing process involves creating a master stencil from a digital file, which is then wrapped around a drum containing ink. Paper is fed through the machine, and the ink is pressed through the stencil onto the paper. A digital document, often in a Portable Document Format (.pdf), serves as the source file for creating the master.
This method provides an economical solution for printing large quantities of flyers, posters, zines, and other promotional materials. Its key advantages include speed, cost-effectiveness for medium-sized print runs, and the ability to print spot colors. Furthermore, it allows for unique artistic expressions. Originally developed in Japan in the 1980s as an office tool, it has found popularity among artists and designers seeking a distinct, hand-crafted look. Its low energy consumption compared to other printing methods is also a notable benefit.
