Xerox Reveals Transient Documents 246

Heartless Gamer writes "Xerox has lifted the veil from some of its research and development work in the field of printing. They demoed the very intriguing 'transient documents.' These offer the prospect of reusable paper in the sense that the content is automatically erased after a period of time, ready for fresh printing. Inspired by the fact that many print outs have a life-span of a few hours (think of the emails you may print out just to read, or the content you proof read on the train journey back home), the specially prepared paper will preserve its content for up to 16 hours."

  • I've got receipts which fade if left exposed to air, off those stupid thermal printers. And, as a bonus feature, they turn utterly black if you set something very hot on them. Possibly useful for taking pictures of the sun with a magnifying glass, if done with care.

    We have a practice in our shop of taking non-sensitive documents and flipping the paper over and running it from a tray for re-use on the blank backside. Fine if people haven't scribbled on it or added a staple.

    After you run a piece of paper through a printer and then handle it, even a little, it isn't suitable to run through the printer again. Usually it causes jams.

      Good point. You should call Xerox right now, because I am sure it never occured to them.
    • Most paper I see used around an office is not suitable to be run through a printer a second time, it is often dog-eared, creased, distorted from someone holding it too long in sweaty hands, stapled, etc...

      It is not uncommon to see loose paper piled next to a printer waiting to be laoded which is already mangled. It is best to store paper in it's pack until ready for use, it keeps the paper clean, dry and undamaged.

    Interesting, but how many times can you reuse paper that has been out in the real world?

    Spilled drinks, people drawing on it with pen, folding, crumping, tearing, chewing.

    I know most printers can't handle the paper if it's not in 100% perfect condition.. I can just imagine the kind of paper jams this thing could produce when someone thwoes in 6 pages stuck together with bubble gum, corners torn off and grease from their lunch calzone smeared all over it.

    Neat idea with the UV though. I love the idea of inkless printing, as long as the paper doesn't end up being more expensive than gold.

      True - and with regular paper costing only $0.01/page, the existing solution comes pretty close to free. Even adding the $0.05/page of ink, it's tough to see why a company/university would make the investment in this sort of paper. Assuming it's costs $1.00/pg, you would need this to last at least 16 iterations, on average, to make it worth your investment.

        Or, you don't use it as a replacement for all of your paper, but as a compliment. Imagine, for a moment, if this paper occupies one of the trays on the office printer, and your print server software knows about it. Maybe you have certain sensitive emails or other documents that are cleared for short-term print, but not to be in print forever. Have your email software, office suite, or whatever be forced to use that tray for those types of documents. Then it becomes more of a CYA thing to avoid potential costs due to the release of information in the future.

        Of course, I can think of at least a dozen ways to bypass that, but it's another possible use for this tech.

      Based on the description in the article, it looks like it'll require a different technology than a standard laser or inkjet printer. It's more like thermal printing. Rather than placing ink on the paper, it temporarily alters the paper.

      If you put this paper in a regular laser printer, you'll still be putting ink on expensive paper -- it won't disappear. And if you put regular paper in the temporary printer, you'll probably get nothing.

Cotton is also used in most papers. Cotton is also a crop that's specially planted for this purpose. Paper is also extremely inexpensive.

    There are only two good reasons to print a document:

  • Inks that were made from slowly sublimating crystals go back a very long way. The idea is that the colour is in the form of something like solid iodine in a medium that slows down the rate at which it turns to its gaseous state. The medium can't follow the writing, though, or the writing is still visible. So Xerox has discovered a better sublimation process. Sounds like basic chemistry, not rocket science.
