Reflected light "palette" is expected to bring inkless printing

A research team from Kyoto University in Japan has newly developed a material that can reflect light of a specific color by adjusting the cracks of OM (Organized Microfibrillation) to form fibrils in an organized manner. Further by adjusting the period of the fibril layer, all visible light from blue to red was successfully generated. The birth of this "palette" of reflected light makes it possible to eliminate the need for ink in future printing.


  Using OM technology, large-scale inkless color printing with a large image resolution of 14000dpi (pixels per inch) can be realized on many flexible and transparent materials. This technology has a wide range of uses, such as anti-counterfeiting of banknotes. The technology can also print on porous materials that are breathable and wearable. For example, in the medical and healthcare fields, OM technology can be used in flexible artificial circuit chips or contact lenses worn on the skin, and the collected biological information can be sent to medical experts directly or through cloud space.
