One of the most dynamic endeavors in the arena of computer technology has been the quest to build a machine that will offer the sharpest rendition of any given image in the highest resolution possible. Through the years, the technology has advanced and there have been numerous innovations for consumer needs, such as three-dimensional printing, which has enabled people to create anything from artificial skulls to Star Wars figures. Unfortunately, despite the innovations in the realm of computer printing, stumbling blocks have come about, which will make the widespread use of this technology possible only many years in the future.
A Pioneering Discovery in Singapore
In August 2012, a team of scientists at the Agency for Science, Technology and Research (A*STAR)’s Institute of Materials Research and Engineering in Singapore have struck upon a method of producing high-definition, full color images at 100,000 dots per inch without using any ink. This resolution is ten times that of top-of-the-line printers, which feature the ability to print images at a mere 10,000 dpi.
A Novel Concept Inspired by an Ancient Idea
Taking their inspiration from the concept of stained glass, which was made by mixing tiny metal fragments into glass, the scientists used nanometer-sized metal disks arranged upon a reflective surface. When the disks come into contact with light, small vibrations their electrons occur, resulting in the adding or subtracting of colors from the visible spectrum, depending upon where the disks are placed. Since the disks are so small, they can be clustered very closely together, yielding a particularly sharp image.
As such, this technique allows coloring to be viewed an idea that has more in common with the concept of etching an image into stone, as opposed to an inking matter. Such a concept could very possibly bring radical change to the notion of how images are printed and further developed.
New Possibilities Abound
It may take a good deal of time before this technology is made widely available for everyday use, especially since the process of 100,000-dpi inkless printing takes hours. However, it bodes well that this innovative method will be particularly useful to industries specializing in high-resolution reflective color displays, anti-counterfeiting measures, high-density optical data storage and perhaps one day might enable more detailed three-dimensional printing. In fact, for months, A*STAR's technology transfer arm, Exploit Technologies Pte Ltd, has been shopping this technology around to potential collaborators in the hopes of finding a suitable licensing arrangement.
