Print on Water

BERDSK, NOVOSIBIRSK, RUSSIA | Sun Innovations demonstrated NEO UV-LED Evolution, a technology said to print on anything — including water — at Glasstech, the Intl. Outdoor Advertising Trade Fair, held Dec. 3-5, 2010, in India.

Sun Innovations' Oleg Markov explains, “Due to interfacial tension on the border of water division [surface tension of water is about 72 dyn/cm, and surface tension of nano ink is 28-29 dyn/cm], ink in the form of thin liquid film stays on the surface of water. Then the ink is instantly cured by UV-LED light; the image transforms into the polymeric film, which also stays on the surface of water due to the difference of densities and adhesion.”

According to the company, the printing equipment is said to offer high levels of efficiency, low energy consumption, and offers “limitless” application on almost all surfaces up to a thickness of 200 mm, with LED curing technology having a life of 45,000 hr. The printer is available in two sizes: 1.6 m and 2.5 m.
