COLOR DIGITAL PRESSES--Decisions, Decisions . . .
The DICOweb is targeted at short-run, full-color jobs ranging from 1,000 up to 30,000 copies, and minimizes the risk of an overspecialized investment for the printer.
For the printer who wants the ability to switch from digital to conventional offset printing, Sakurai has developed a "hybrid press"—the Oliver 474EP II DI press. The four-page press will initially be available in a four-color version with perfector and can be run in either DI or conventional mode. Five- and six-color versions are planned for introduction at a later date.
The Oliver 474EP II DI incorporates Presstek ProFire integrated imaging technology. "What sets us apart from our competitors is the press' ability to run the ProFire DI technology or conventional offset plates, reports Steve Bruno, national service manager for Sakurai. "The press is not dedicated to just being a DI press. We can also run it with conventional plates."
xpedx, Import Group
Also taking advantage of Presstek ProFire technology is the xpedx Import Group, which offers the Ryobi 3403 DI, an A3-size, portrait format, four-color offset press with built-in direct imaging.
Jointly developed by Ryobi and Presstek, the DI press employs an infrared laser to burn images directly onto mounted plates, enabling CTP handling of digital prepress data and eliminating film output and image exposure onto the plate.
The FirePower laser diode emits four beams through a single lens. Six such diodes are mounted on one imaging head. Therefore, 24 laser spots can be addressed simultaneously by each imager. Also, the plate cylinder rotates at 18,000 rph during imaging.
Screen offers the TruePress 544 B3-size, four-color digital press that uses on-press imaging to expose and develop the printing plate. The company also offers the TruePress 744, a four-color, B2 press that is fully automated and capable of 8,000 iph with on-press imaging.
