First full colour images at 100,000 dpi resolution with help of nanotechnology
Phys.Org summary of some research out of Singapore:
Researchers from A*STAR’s Institute of Materials Research and Engineering (IMRE) 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.
I’d be dishonest if I didn’t admit that a huge chunk of the reason I’m linking this is because the folks are from a place called A*STAR.
