A Risograph machine is a stencil based digital duplicator, which is incredibly energy efficient because it does not use heat and very little electricity. Unlike laser or ink jet printers it prints one colour at a time by passing ink through a ‘master’ which is attached to an ink drum.
The machine has interchangeable colour drums and inks, which allows for printing many different colours in one print job. Risograph printers use inks that are made from vegetable soy oil or rice based ink, making it a sustainable printing process. Riso inks are slightly transparent, so a print’s appearance will also depend on the colour of the paper they are printed on. Colours can also be overprinted to create new tones and variations.

WHAT PAPERS DO WE PRINT ON?
Our risograph machine can only print on A3 or A4 paper between 80 and 250gsm. Due to the nature of riso inks, we are only able to print on uncoated paper.
We stock a range of papers suited to risograph printing and publication making. All our papers are recycled, FSC certified or otherwise donated, with the correct texture to absorb the ink nicely and bind neatly. It is not guaranteed that paper sourced elsewhere will work with our equipment and could cause waste and unsatisfactory results.
In addition to these in-house papers, we are happy to order in any special paper you require. When ordering paper in, we may ask that you purchase the whole ream, as it might be something we wouldn’t normally be able to use or sell. We regularly order heavier weights of Context colours, Pop’set and Colorplan, Fedrigoni, Munken or Olin papers on request.
