Presstek Reports Improved Sequential First Quarter 2011 Revenue and Profit

• Service revenue declined 8.7% to $6.0 million in the first quarter of 2011 compared to the year-ago quarter. This decline is primarily due to the continued erosion of the analog service base, lower installation revenue and a general trend by customers to delay service calls and maintenance to save money in a difficult economy. Service revenue has remained fairly stable during the past four quarters.
