- Companies to Cooperate in Placement of Screen PlateRite Platesetter Imaging Presstek Aurora Chemistry-Free Thermal Plates - HUDSON, N.H., Sept. 12 /PRNewswire-FirstCall/ -- Presstek, Inc. (NASDAQ: PRST), a leading manufacturer and marketer of high tech digital imaging solutions for the graphic arts and laser imaging markets, and Screen USA, a leading supplier of systems and components for the graphic arts industry, today announced a strategic alliance under which Presstek and Screen will cooperate in the placement of Screen PlateRite CTP systems with Presstek's new chemistry-free Aurora thermal plates. "We are delighted to be cooperating with Screen to offer this innovative CTP solution. Screen PlateRite platesetters are already recognized as one of the industry's premier CTP solutions, when combined with the benefits of Presstek's chemistry-free Aurora plates the customer will have a more productive and cost-effective solution," said Peter Bouchard, Presstek's Vice President of Marketing. "Presstek solutions are designed to simplify the way people print by eliminating steps, materials, and labor through technology advancement, our cooperation with Screen is another way to deliver this promise to the market." Presstek Aurora thermal chemistry-free plates are compatible with FM screening solutions and are designed to take advantage of maximum PlateRite platesetter throughput with no degradation in quality. Once plates are imaged, a simple water wash is all that is required prior to mounting plates on press. Aurora plates are 100% chemistry-free, no chemical processing, baking, or gumming is required, resulting in significant savings in time and materials. Because Presstek Aurora plates are chemistry-free, all they require after imaging is a simple water wash. This eliminates the need for chemistry, as well as any requirement for baking, gumming, developing or finishing. This translates to significant savings in time and cost, and a reduction in platesetter footprint to free up valuable production space for more productive uses. "We have been very pleased with the results delivered by the combination of Screen PlateRite platesetters and Presstek Aurora chemistry-free thermal plates in our field testing over the past year," said Michael Fox, Vice President of Sales at Screen USA. "We expect that by working closer together with Presstek we can bring this solution to a larger portion of the market." Screen will be displaying PlateRite platesetters with Presstek Aurora chemistry-free thermal plates at Booth 6100, at Print 05, the largest printing trade show in North America, being held at McCormick Place, Chicago, from September 9th through 15th, 2005.
