The colours are based on a mixture of water, soy, and rice bran oil - this natural composition can lead to minimal rubbing off of colours upon touch. Also, a possible slight offset and varying colour application testify to true craftsmanship and make each print a unique piece.

Risography is considered one of the most environmentally friendly and energy-efficient printing processes - similar to screen printing. It allows the reproduction of a large number of copies with low energy consumption. The colours used are also based on natural oils, are resin-free, and free from volatile solvents.
