Color printing at highest resolution possible enabled by use of arrays of metal-coated nanostructures

Commercial laser printers typically produce pin-sharp images with spots of ink about 20 micrometers apart, resulting in a resolution of 1,200 dots per inch (dpi). By shrinking the separation to just 250 nanometers—roughly 100 times smaller—a research team at A*STAR can now print images at an incredible 100,000 dpi, the highest possible resolution for a color image. These images could be used as minuscule anti-counterfeit tags or to encode high-density data.
