At Xerox, It's Here Today ... Gone Tomorrow!

Just when you begin to think that paper documents are about to be a thing of the past ... "Everything is going digital!" ... Xerox reveals that it still is applying R&D assets on hardcopy processes.

That's right, there is an identified need to have a printed (on a sheet of paper) document that has a ticking-time value for its intended use. The image is applied to the paper, then, after about sixteen hours, the image disappears.

We at Symblogogy will define the document derived from this process as a "Workday Lifetime Document" or WLD.

Xerox reveals transient documents
By Alun Williams – PC Pro - Thursday 7th September 2006, 11:04 AM

Xerox has lifted the veil from some of its research and development work in the field of printing. The cutting-edge research highlighted at a press event involved current projects that are expected to see the commercial light of day within 18-months, including a twist on the theme of invisible ink.

Mario Jarmasz, an engineer from one of the company's R&D centres, in Grenoble, was speaking at the launch of the Xerox's entry-level A4-only multi-function printers. As well as a looking at 'print infrastructure mining', which brings the techniques of data mining to enterprise print logs to better optimise the flow of print jobs around an organisation, he also demoed the very intriguing 'transient documents'.

This offers 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.

The paper has a photochromic compound that changes from a clear state to a coloured state under ultra-violet light. This can create the print face, which will duly fade with time. Further research is being undertaken to give the option of subsequently preserving the content if the user desires, which might literally involve warming up old data through the heating of the paper.

Jarmasz also demonstrated the company's work on mobile document imaging, for example capturing data from business cards through a process of OCR compression and then transmission. Possible developments of this work include expanding email interfaces to incorporate handwritten input and the management of distributed forms.

Xerox, of course, is legendary for its Palo Alto Research Center (PARC), which claims credit for developing Ethernet and laser printers as well as the first personal computer. Having developed the machines, the researchers then wanted to connect them and then to print, and the rest is history.

Xerox touts erasable paper, smart documents
The hi-tech paper can be reused up to 100 times
By Agam Shah - April 29, 2008 (IDG News Service)

Xerox Corp.'s research arm yesterday showcased its latest innovations, including erasable paper and tools that make documents "smart" by adding a deeper meaning to words and images.

Since its establishment in 1970, the Palo Alto Research Center Inc. (PARC), funded by Xerox, has created numerous technologies now available on PCs, including Ethernet, the graphical user interface (GUI) and the computer mouse. The laboratory, with other Xerox research facilities, is now trying to help its parent company and other start-ups by focusing on printing and other innovations to access, use and secure electronic documents.

Scientists demonstrated paper that can be reused after printed text automatically deletes itself from the paper's surface within 24 hours. Instead of trashing or recycling after one use, a single piece of paper can be used a second time, and reused up to 100 times, said Eric Shrader, area manager at PARC.

Predictions that paper would disappear in the 1970s in favor of electronic documents were wrong, Shrader said. As the number of electronic documents produced increases, about two to five pages are printed in the office for daily use, like e-mail messages and Web pages, which are discarded or recycled after being read. Reusable paper reduces waste, is environmentally safe, and helps reduce overall printing and paper costs, Shrader said.
