Highest Resolution Printer
The highest quality printing has been reached according to some scientists. The image might look a bit grainy but it is actually the width of a human hair (50 micrometres across). The printer has been developed by researchers at the Agency of Science, Technology and Research in Singapore which can print images at a staggering 100,000 dots per inch in full colour.
This new method of printing boasts resolution ten times more than the highest-resolution laser and inkjet printers. It works by each pixel being printed by depositing four nanoscale posts just a couple of nanometres tall, which are then capped with silver and gold nanodisks. By varying the diameter of these post structures and the gaps between them, its possible to control what colour of light they reflect. In fact if the pixels were any closer to each other then the light reflecting off them will defract and blur together, which brings some people to the conclusion that this is the highest resolution printing that is possible.
