About Risograph Printing
Risograph printing is a vibrant and economical method of producing anything from books to artist prints. It sits in a realm somewhere between screen print and photocopy, but at a fraction of the cost. The Risograph bridges the gap between a standard photocopier (which is cheaper up to about 20 copies) and using a commercial printer (cheaper over about 5,000 copies).
Riso inks are soy based and do not exactly conform to any colour standards. These colours are also slightly transparent and allow for variations in overprint and based on the color of paper they are printed on.
The Risograph works by transferring artwork onto a master (or screen). The master is wrapped around a drum filled with ink. The paper is then fed flat through the printer whilst the ink is pushed through the master, onto the paper, while the drum rotates at high speed.
