They are the highest resolution images ever, 1,00,000 dots per inch, and they are produced without ink! A team of researchers at the Institute of Materials Research and Engineering (IMRE) in Singapore has demonstrated the creation of sharp, full-spectrum colour images at 1,00,000 dpi, a massive improvement over inkjet and laser jet printing which are only able to do about 10,000 dpi.
The team’s full spectrum images were creating using metal-laced nanometer-sized structures, eliminating any need for dyes or inks. Their method approaches coloring as lithographic matter instead of ink. With its nano structure surface, light is then reflected creating the colour images. Its a process reminiscent of how stained glass windows function. The resulting resolution, as Dr Karthik Kumar explains, “depends on the size and spacing between individual nanodots of color.”
Though this technology is still new and being developed, these early results indicate yet again that the days of turning on your printer and finding out your ink cartridge is empty, are numbered.
