We stock 24 inks in unique Risograph spot colours which are semi-transparent, allowing them to be overlaid to make new shades; with the exception of Metallic Gold which sits on the surface of other colours and is a nice alternative to foiling. The appearance of the ink also changes depending which paper they're printed onto. Pantone codes are approximate.
Inks are rice bran oil based and don't contain a fixing agent, so never completely dry - a bit like newspaper ink. They are extremely eco-friendly and non-toxic. We recommend a maximum of 5 colours per print job. Metallic Gold, Fluorescent Green & Fluorescent Yellow are £0.25 extra per print impression.
