Since the dawn of printing technology, people have expressed concerns over
how many trees must be felled in order to produce enough paper to keep
up with demand. That issue was improved significantly by the invention
of the paper recycling process. Now, a new technology is on the horizon
that could change the printing industry again and make it greener than
ever: re-printable paper.
Re-printable? Yes, you read that right. Researchers at the University of
California Riverside decided to come up with a type of paper that could
be printed on, easily erased without damaging the paper, and then used
again. The process they came up with uses a specialized process involving
ultraviolet light to cure a type of redox dye that’s already commercially
available. This is a huge benefit for those interested in this new technology
because it means that integration and widespread use may not be far off
should the process be perfected!
Another more complex system utilizes a mixture of redox dye combined with
titanium oxide particles, which can then be applied to a piece of conventional
printer paper. A light-based printer (either ultraviolet light or a more
conventional laser system) then creates the image on the piece of paper
using a photo mask to make the image appear. The result is a print process
that requires no ink or toner and can produce images in extremely high
The erasing process is also fairly simple: simply heating the paper to
a high temperature causes the image to disappear, allowing it to be re-printed.
Researchers have been able to erase and reprint a single sheet of paper up to
eighty times before it needs replaced!
At the moment, this technology is still in its infancy, and as a result
there are hurdles that need to be overcome. At the moment, oxidation causes
prints to disappear in roughly a week’s time. However, as technology
advances and new materials are created that won’t be damaged by
the air around us, loads of applications will be able to make practical
use of this paper-saving method.
