Printing on water - this is not a fiction, but the reality. Company Sun Innovations is the creator of printing technology on water, proving that UV printer SUN Universal UV-LED can actually print on any surface. Inks are retained on water surface due to separation of inter-facial tension liquids, then they are solidified with ultraviolet light, and the image is converted into a polymer film, which also stays on the surface of water due to density and adhesion differences.
