Using a metal-laced nanometer framework, they have managed to create a series of high-resolution color images several times sharper than typical output of ink jet and laser jet printers, which can manage a maximum of 10,000 dots per inch, scientists at the Agency for Science, Technology and Research reported Monday.
"The resolution of printed color images very much depends on the size and spacing between individual 'nanodots' of color," researcher Karthik Kumar said.
"The closer the dots are together and because of their small size, the higher the resolution of the image. With the ability to accurately position these extremely small color dots, we were able to demonstrate the highest theoretical print color resolution of 100,000 dpi."
The technology could lead to future high-resolution reflective color displays, anti-counterfeiting and high-density optical storage, the researchers said.
The research was published in the journal Nature Nanotechnology.
