Presstek Announces Availability of Presstek 52DI® Press for the North American Market

HUDSON, NH—September 12, 2006 —Presstek, Inc. (Nasdaq: PRST), a leading manufacturer and marketer of environmentally responsible digital offset printing business solutions for the graphic arts markets, today announced that the Presstek 52DI digital offset press, first released in April to the European market, is now available for the North American market. This 52cm landscape press will be showcased at Graph Expo 2006 in Booth #3822 at McCormick Place in Chicago from October 15th through 18th, 2006.

“Market research documents it, and our customer base confirms it – short-run, high quality color is a key growth opportunity for today’s print service providers,” said Geoff Loftus, Presstek’s General Manager for Presses. “The Presstek 52DI, a 52cm landscape press, allows print service providers to capitalize on the markets’ move towards short-run color by producing high quality printing – quickly, efficiently and profitably. The 52DI’s level of flexibility, speed, quality, ease-of-use, and productivity provides a breakthrough for printers who are faced with the daily reality of quickly producing a broad variety of short-run color work – and doing so profitably.”

The Presstek 52DI, making its North American debut at Graph Expo, is a highly automated 52cm landscape sheetfed four-color digital offset printing press that combines the efficiency of an all-digital workflow with the versatility and quality of a conventional waterless press. The prepress file can be sent directly to the DI where the entire plate handling process is totally automatic – all four plates are imaged on-press in precise registration. This eliminates manual intervention such as the loading or unloading of plates in-between jobs, while reducing steps and potential errors. The 52DI also features Presstek’s unique Zero Transfer Printing (ZTP) process in which all four colors are laid down on the sheet without any transfer between grippers, whereas a conventional press requires tower-to-tower sheet transfer which challenges registration and restricts substrate choices. Eliminating sheet transfer delivers first sheet registration and results in an unsurpassed level of sheet-to-sheet and job-to job-consistency and repeatability. In addition, it expands the available range of printing media – including 20 pt. stock, styrene, converted envelopes and pocket folders.
