COLOR DIGITAL PRESSES--Decisions, Decisions . . .
Xerox entered the digital offset printing arena first at DRUPA 2000 with its DocuColor 400 DI and DocuColor 233 DI offerings. The DocuColor 400 DI is based on an Adast design, while the 233 DI is based around a Ryobi press.
Both presses offer the same fifth-generation Presstek ProFire direct imaging technology. ProFire is a filmless, laser imaging system designed to produce printing plates directly from the computer. The system includes all the components needed for high-quality output, customized computer system and control of the imaging process, as well as an IR-based laser diode array.
The DocuColor 400 DI is designed to enable a larger format while providing higher volume runs in shorter times. It offers a 12,000 iph maximum print speed, uses a landscape 15x201⁄2˝ sheet and can image a printable area of 141⁄2x19.88˝.
An optional fifth printing tower on the DocuColor 400 DI can be used for custom color applications, versioning or for varnishing. The press is equipped to provide either 1,270 dpi or 2,540 dpi resolution, depending on application requirements.
The DocuColor 400 DI is the fastest total-makeready press of any direct imaging press that is commercially available, according to Xerox's David Tashji, general manager of business development, worldwide graphic arts industry marketing. "The total makeready time for the DocuColor 400 DI is nine minutes—and that is from the end of the last job to the first usable sheet of the next job, as was shown in recent live demonstrations," he states.
The DocuColor 233 DI is designed specifically to produce on-demand, short-run color. It is a small footprint, entry-level system that provides 7,000 iph maximum print speed. The 233 DI uses a portrait format, maximum sheet size of 18.11x13.39˝ and a maximum image area of 12.99x17.72˝.
Both machines are currently in beta testing. The 400 DI is expected to be commercially available in the first quarter of this year, while the 233 DI is expected to be available in the second quarter, according to Tashji.
