 Patented High-Resolution Dry Processing Film a Productivity and
 Environmental Achievement; Creates New Market Opportunity
 STAMFORD, Conn., Nov. 1 /PRNewswire/ -- Xerox Corporation (NYSE: XRX) today announced it has created a dry processing film that will obsolete silver halide film and provide an environmentally sound alternative for many applications in the printing industry.
 The film, which eliminates the need for chemical processing, is the company's first product in an estimated $1.8 billion market.
 Called VerdeFilm, this patented material creates images equal to or better than the best silver halide film, and removes the environmental hazards and costs associated with conventional chemical film processing. VerdeFilm requires no special handling or storage, and is not affected by accidental exposure to daylight.
 Printers use film to capture images that are then transferred to plates used on printing presses for the production of magazines, catalogs and other commercial jobs.
 "The VerdeFilm product is an outgrowth of research in electrophotography and is an excellent example of leveraging our core technology in document development into entirely new markets," said Joseph D. Wright, vice president, Xerox Research Centre of Canada (XRCC), where VerdeFilm was invented.
 VerdeFilm will be marketed by VerdePrint Technologies, a new Xerox business unit. The first of several products based on technological innovations developed at the XRCC, VerdeFilm is protected by more than 10 patents covering its invention, manufacturing and applications.
 Instead of a silver halide film developed with chemicals, color separations and monochrome VerdeFilm images are created using a thin layer of minute particles of selenium that are charged, exposed to light and developed using heat in a process no more complicated than feeding paper into a fax machine.
 Printers will either upgrade or modify existing equipment to enable the use of VerdeFilm.
 VerdeFilm provides an economically and environmentally sound alternative as governments worldwide limit silver and chemical effluent contamination created as a by-product of traditional film use. In the United States, the Environmental Protection Agency is strongly supporting congressional reauthorization of the Clean Water Act.
 VerdeFilm, named for its ecological benefits, will be marketed at a price comparable to traditional films. However, printers will realize substantial savings by eliminating processing that generates waste chemicals and consumes large amounts of energy and water.
 A standard chemical film processor, running in-line with an imagesetter, yearly consumes about 200 gallons of developer and fixer, which is typically diluted and flushed. VerdeFilm has been classified in California as "casually disposable," meaning it does not pose a health or disposal hazard, although VerdePrint Technologies plans to recycle exposed films and extract the selenium for reuse in new film production.
 Evaluations of VerdeFilm masters in standard test forms, control strips and full-color images have been conducted by a number of industry experts.
 "Our tests indicate that VerdeFilm is equal to, or better, in quality, run length, and resolution than current silver films used by the industry for mastering plates for magazines, newspapers and commercial printing," said Frank J. Romano, the Melbert B. Cary Jr. Distinguished Professor of graphic arts, School of Printing Management and Sciences, Rochester Institute of Technology, Rochester, N.Y.
 VerdeFilm's thin layer of minute selenium particles are encased within a polymer coating, where they remain throughout the life of the film. A combination of heat and light in the image areas causes the selenium molecules to migrate deeper into the polymer, which creates a visible image.
 Selenium, produced as a by-product of copper refining, is already widely used in the imaging drum of photocopiers. The difference in the VerdePrint invention is that after exposure, the image is permanent.
 At its introduction today at Graph Expo in Chicago, VerdePrint Technologies announced it will bring the VerdeFilm products to market by working in collaboration with allies in the graphic arts industry, including: Agfa, a division of Miles Inc.; ECRM; Optronics; Ultre; 3M; Quebecor Printing Inc.; Business Link Communications and Image Innovations. These alliances include manufacturers of film, as well as manufacturers of imagesetters and scanner recorders and users.
 Two types of VerdeFilm are being introduced for trial-testing during the second quarter of 1994, covering the full spectrum of imaging sources.
