These exceptionally rich, non-toxic, water-based inks work great for all types of monotype techniques. The unique slow-drying formula allows plenty of time to create an image on the plate. Because Akua stays wet on the plate, there's no need to soak paper before printing. Clean, brilliant, lightfast colors are exceptionally strong yet transparent — no chalk, fillers, or polymers are added. Use Akua modifers to adjust sheen, thickness, and transparency. Akua Liquid Pigment cleans up fast and easy with water. They can also be used for Japanese woodcut and drawing on paper. Inks come in 4 oz (118 ml) containers.
