The Risograph

What is Risograph printing?

The Risograph Printer or “RISO” works by transferring an image onto a thin stencil, called a master. This printing process is similar to screen-printing in the sense that ink is pushed through a prepared stencil. Once a master is made, it is applied to a drum, which holds the ink tubes. The Risograph uses a soy-based ink similar to the ink used to print newspapers. Like newspaper inks, Risograph inks never fully dry, so a Risograph print will smudge slightly if you touch it. For this reason, the Risograph can only print on uncoated papers. 

Our Risograph, the MZ1090, holds two ink drums, making it possible to print two ink colors at one time. The ink drums are housed inside a machine that looks and works like a traditional photocopier. As a result, the Risograph can print at a very high speed, making it ideal for printing in large quantities. Currently, our lab has 8 colors: black, green, fluorescent pink, blue, bright red, yellow, metallic gold, and white!
