Expanded Presstek DI® Digital Offset Press Portfolio Will Be On Display at IPEX

• New Presstek 75DI featuring six minute job-to-job turnover makes worldwide debut
• Presstek 52DI-AC on exhibit for the first time in Europe

BIRMINGHAM, UK—May 19, 2010—Presstek, Inc. (NASDAQ: PRST), a leading supplier of digital offset printing solutions to the printing and communications industries, today announced that it will be demonstrating a wide-range of DI digital offset presses at IPEX, scheduled for May 18-25, 2010, in Birmingham, UK. Presstek will be located in Hall 7, Stand C480. The Presstek 75DI press will make its worldwide debut at the show, and the Presstek 52DI-AC will be on exhibit for the first time in Europe. These highly automated digital offset presses deliver exceptional quality and cost-effective short-run color to the world of offset. With optimum print runs of 500 to 20,000, Presstek DI digital offset presses bridge the gap between digital toner and conventional offset printing, making them a complementary addition to print shops of all sizes.

"We will be featuring the new Presstek 75DI at IPEX," said Jeff Jacobson, Chairman, President & CEO of Presstek. "We believe that many larger printers have been waiting for a press that offers the business advantages of the Presstek 75DI to round out their production portfolios. We anticipate strong market approval of this breakthrough product when visitors see it being demonstrated on the IPEX show floor."

With a Presstek DI digital offset press, a digital file is sent directly to the press without the use of offline platemaking processes. All plates are simultaneously imaged on press in precise register; automated press settings help ensure consistently high quality throughout the run without significant operator intervention. With the new Presstek 75DI a complete makeready, including plate imaging, takes only six minutes.

Presstek's portfolio of DI digital offset presses provides the most environmentally-friendly offset printing solution on the market. Environmental benefits include: chemistry-free on-press platemaking, waterless printing, support of recycled papers and vegetable-based inks, no use of fountain solutions significantly reducing VOC's, and fast makeready which results in significantly reduced waste.

"Many forces have combined to raise the interest in environmentally friendly printing," said Guy Sasson Presstek’s President, Europe, Africa, and Middle East Region. "This includes print buyers looking for printers to produce printed materials in a more sustainable manner, rising commodity prices such as paper, ink and energy, increased government regulations, and the demand for shorter runs. These changes are part of the ever evolving marketplace, and innovative solutions like Presstek DI digital offset presses are meeting these requirements."
Presstek's DI Digital Offset Portfolio

Presstek DI digital offset presses are available in three basic models, the Presstek 75DI, the Presstek 52DI and the Presstek 34DI. The table at the end of this release offers a comparison of these presses.

The new Presstek 75DI digital offset press continues the Presstek DI tradition of very high quality (300 lpi or stochastic screening); extreme automation (6-minute job-to-job turnover); and a small environmental footprint with waterless printing technology, chemistry-free imaging on-press, fast run-up for minimal waste, and consistent quality from job to job and within each job.

In addition, the Presstek 75DI press incorporates significant technological advances, including utilization of new on-press imaging technology. This next-generation imaging technology utilizes a single lens imaging concept in which all diodes image through a single lens, resulting in improved image quality and even easier makeready. The efficiency of the press is further enhanced by a simultaneous imaging and cleaning of plates that optimizes the makeready time between jobs.

“We are also pleased to be demonstrating the Presstek 52DI-AC at IPEX, being shown for the first time in Europe,” added Jacobson. “The 52DI-AC’s inline aqueous coater supports both flood and spot aqueous coating. This expanded DI press portfolio truly offers choices that can meet the needs of print shops and in-plant operations of all sizes and demonstrates Presstek’s dedication to expanding the range of applications, sizes of businesses, and market segments for which these presses, unmatched in the marketplace, are ideally suited.”

Presstek DI presses are the ideal complement for shops with larger conventional offset presses that need to extend the range of applications they can produce, make shorter runs more profitable and maintain the high level of quality that will ensure their ability to remain competitive in a consolidating market. They are also complementary to production-level digital toner-based presses that can be expensive to operate for runs of 500 sheets or more. Presstek DI presses truly provide the bridge for high quality, profitable print for run lengths from 500 to 20,000 impressions.
