Xerox Develops Auto Erasable Paper, Prints on the Paper will Disappear in 24 Hours

Scientists at Xerox have developed a way to make prints whose images last only a day. The technology creates temporary images using compounds that change color when they absorb a certain wavelength of light but then will gradually disappear, so that the paper can be used again and again. Xerox calls the technology “erasable paper” and the paper self erases within 16-24 hours. Xerox collaborated with PARC (Palo Alto Research Center Inc.) to develop the technology. PARC has already developed a prototype printer that creates the images on the paper using a light bar that uses a specific wavelength of light to print on the paper. The “erasable paper” is part of Xerox’s ongoing investment in development of green products and the company estimates that as many as two out of every five pages printed in a office are for single viewing only. Using of erasable paper will reduce paper usage by as much as 30% in a typical office environment. Commercial products based on this technology are still far away as the technology is still in experimental stage.
