PALO ALTO, Calif., December 8, 2005 — HP announced that the Rochester Institute of Technology’s Printing Applications Laboratory Worldwide Media Center (WWMC) held an Industrial Printing event today dedicating its new seven-color HP Indigo press ws4050. Participants in the event included HP and RIT officials, as well as officials from Michelman Inc., maker of the DigiPrime primers used to enhance the performance and shelf life of many certified HP Indigo media. During the event media suppliers representing some of the leading names in the paper and specialty substrates industries began the process of submitting a new round of media for official WWMC certification screening on HP Indigo presses. “So far, more than 700 different media have been certified for use on HP Indigo presses,” said Hans Van Veen, director, Indigo Supplies and Media, HP. “Now, with the Worldwide Media Center’s new HP Indigo press ws4050, our industrial printing customers will have even more substrate choices to create profitable, cost-effective, and unique digitally printed products.” Established earlier this year, the WWMC evaluates media from HP and leading suppliers for independent, authoritative certification to ensure compatibility and high productivity on HP Indigo presses. Because of the WWMC’s active and successful third-party approval process, HP Indigo presses print on the industry’s widest range of approved substrates for high-end digital color printing. Of the 700 media solutions worldwide approved for use, more than 80 new media have been approved in the U.S. since January 2005. “The new seven-color HP Indigo press ws4050 enables an expansion of the services we have been proud to deliver to HP as well as its media suppliers,” said Bill Garno, director, RIT Printing Applications Laboratory. “The package printing market provides many new opportunities to leverage digital printing, including label production. All of these applications require a diverse range of substrates.” Start-to-Finish Capabilities on the HP Indigo ws4050 The HP Indigo press ws4050 delivers best in class print quality and high press utilization, making it the ideal solution for cost-effective, on-demand, short-to-medium-runs of full color labels, as well as a high-value printing solution for shrink sleeve packaging.
