Highest quality colour images produced
The image on the left is before the addition of metal in the nanostructures. The image on the right shows colours under the same microscope after the addition of the metal layers to the nanostructures in specific patterns. Current industrial printers can only achieve full-spectrum colour images up to 10,000 dots per inch (dpi), whereas the new method relies on metal nano-structures and can produce full colour images at 100,000 dpi. Image: Nature Inspired by colourful stained-glass windows, researchers from Singapore have demonstrated an innovative method for producing full-colour images at 100,000 dots per inch (dpi) which can be used in reflective colour displays, anti-counterfeiting, and high-density optical data recording. Researchers from A*STAR’s Institute of Materials Research and Engineering (IMRE) have developed an innovative method for printing sharp, full-spectrum colour images at 100,000 dpi, using metal-laced nanometer-sized structures, without the need for inks or dyes. In comparison, current industrial printers such as inkjet...
