In a press release issued earlier today, Heidelberg indicated that the enhanced Quickmaster DI Pro, enabled by Presstek's new ProSpot technology, offers optimum print quality, a powerful workflow, as well as impressive cost- effectiveness. Visitors to drupa 2004 will be able to see the benefits of this new technology in print demonstrations scheduled to run at the Heidelberg exhibition. "We are pleased that Heidelberg has again demonstrated its commitment to direct imaging presses with the announcement of the enhanced Quickmaster DI Pro," said Presstek's General Manager for On-Press Imaging, Peter Bouchard. "We continue to be proud of our contributions to Heidelberg's DI offerings."
