Take a look at the picture included with this article. Sure it’s not exactly the prettiest and you could be forgiven for saying that it looks crappy. Now take into account the size of the actual image and things change. The picture in question is printed at the size of 10 nanometers, or 0.00000039 inches.
The impressive feat is due to a nanotechnology breakthrough that allows for a potential print resolution of 100,000dpi. The process is complicated, but takes inspiration from stained glass and uses ultra thin metal film instead of traditional ink to create color.
This breakthrough has great potential for printing in the future, but also for high-resolution monitors and even optical data storage.
