'Stained glass' nanotechnology capable of printing up to 100,000 dpi

Researchers in Singapore have managed to create high-resolution color images several times sharper than typical methods using a metal-laced nanometer framework. While normal inkjet and laser jet printers can reel out up to 10,000 dots per inch, this nanotech-based technique has a theoretical limit of around 100,000 dpi. The technique is closer to lithography than typical modern printing, and could pave the way for future high-resolution reflective color displays and high-density optical storage. Scientists crafted precisely patterned metal nano structures, and designed the surface to specifically reflect the intended color. According to project leader, Dr Joel Yang, "The team built a database of color that corresponded to a specific nanostructure pattern, size and spacing," with an ultra-thin metal film spread across the image activating these "encoded" colors. Looks like yet another reason to upgrade our dull fleshy retinas.
