The risograph has it's own special colour pallet. The soy-based inks also allow you to overlay colours in order to create new ones. This means you can event print CMYK images. Dopple has 10 colours and growing!
The Risograph creates a stencil from banana paper. This is then wrapped around a one colour ink drum and soy ink is pushed through the voids. As the paper glides over the rotating drum it imprints your artwork onto its surface. The colours are then layered up to create your masterpiece.
Riso is the only environmentally friendly form of printing and when you work with Dopple you should know we take that seriously only stocking 100% recycled paper and packaging.
TL:DR It's a cool eco-friendly screen printing machine
