What Is Riso?
Risograph printers were designed and released in Japan in the 1980s as a way to print efficiently and economically. Still used by small to mid-size organizations, artists and designers have adopted riso printing for its unique, vibrant and paint-like aesthetic. Speedy, efficient and eco-friendly, risograph printers employ a process similar to screen-printing with stencils and layers of ink.
The original is scanned through the machine and a master is created, by means of tiny heat spots on a thermal plate burning voids (corresponding to image areas) in a master sheet. This master is then wrapped around a drum and ink is forced through the voids in the master. The paper runs flat through the machine while the drum rotates at high speed to create each image on the paper.
Here at Secret Riso Club, our Riso is a EZ390u , and we print a variety of publications and artwork, including posters, zines, illustration, flyers, postcards and brochures.
