This is not a copier.
The risograph or Riso is a digital press, invented in the late twentieth century to fulfill the high output requirements of churches, law firms, and schools. In recent years this technology has been adopted by artists and designers for its unique and appealing aesthetic.
After digital files are prepared and sent to print, the riso burns a stencil of your image into a natural fiber paper like “master”. The master is wrapped around a color drum and spins as paper is fed into the machine. Ink is pushed through the master making a print on the paper. Colors are printed one at a time and register will occasionally be slightly off (colors not exactly lining up). This slight variation within the edition is one of the many great Riso qualities.
Riso inks are non-petroleum, soy-based, and low VOC. Below are our available ink colors and color value scale ranging from 100% to 10%.
More colors can be produced by layering/mixing inks (process colors)

The risograph can only print on uncoated paper, with a maximum paper size of 11×17.
It is a good idea to keep the Riso printing process in mind when designing your project. Take a look at our available ink colors and their value scales(above) to help you with this process.
Files are sent to print in the form of 8.5 x 11″ or 11 x 17″ grayscale pdfs. Each color will require its own pdf. In your design black will equate to 100% coverage of whatever color is being printed, lighter grays generate less coverage and therefore create lighter values (as long as a light colored paper is being used).
We are happy to help you with this process or answer any questions you may have.
