What is risograph ?Risographs are printing machines created in Japan the eighties.
They use a stencil-printing technique (comparable, for example, to screenprint) with soy-based inks.
They initially gained popularity due to their fast printing output, relative ease of use and affordability.
In the past few years, the number of printing shops offering risograph services started to flourish, as the printing technique came back in fashion : the technique is appreciated for it's results close to screenprint for a much affordable cost, the vividness of colors, and the availability of new inks allowing to print in fluorescent, white or metallic tones.

1. RISO PRINTING WORKFLOW BASICS
- Each color has to be prepared as a greyscale file
- Each color will be printed on top of each other by the riso printer
- The printer will print only one color in each pass
