First full colour images at 100,000 dpi resolution
Researchers have developed an innovative method for creating
sharp, full-spectrum colour images at 100,000 dots per inch (dpi), using
metal-laced nanometer-sized structures, without the need for inks or dyes. In
comparison, current industrial printers such as inkjet and laserjet printers
can only achieve up to 10,000 dpi while research grade methods are able to
dispense dyes for only single colour images. This novel breakthrough allows
colouring to be treated not as an inking matter but as a lithographic matter,
which can potentially revolutionise the way images are printed and be further
developed for use in high-resolution reflective colour displays as well as high
density optical data storage.
