HUDSON, N.H. – March 13, 2008 – Presstek, Inc., the leading manufacturer and marketer of digital offset business solutions, today announced it has been notified by the U.S. International Trade Commission (“ITC”) that it is instituting an investigation related to the Company’s previously announced complaint against Israeli printing plate manufacturer VIM Technologies, Ltd. and its manufacturing partner Hanita Coatings RCA, Ltd. for infringement of Presstek’s patent and trademark rights. Presstek also sued three U.S. based distributors of VIM products: Guaranteed Service & Supplies, Inc., Ohio Graphco, Inc., and Recognition Systems, Inc., as well as one Canadian based distributor, AteCe Canada. Presstek is seeking, among other things, an Order from the ITC forbidding the importation and sale of the VIM printing plates in the United States; such an Order would be enforced at all U.S. borders by the U.S. Customs Service.

“The quick and favorable response to our complaint with the ITC is encouraging,” commented Jeff Jacobson, President and Chief Executive Officer of Presstek. “We intend to aggressively defend our valuable intellectual property both in the United States and abroad.”
