COLOR COPIERS & DUPLICATORS -- Creating Color that Clicks
The RISO 3700 digital press can reside on a network and handles stock sizes from 4x6˝ to 11x17˝ and weights from 13 lb. to 110 lb. A more sophisticated production system can be created by adding peripherals to the print engine, Barrett says. For example, a variable addressing unit can be rolled up to a RISO digital press to add printing of a return address, teaser messages and address information.
Duplo's DP-63 Series digital printing systems offer high-speed printing at 600 dpi, Liao notes. Both the DP-63P and DP-63S models feature master and ink systems that reportedly produce sharp images while maintaining minimal ink consumption. The DP-63P has a computer interface, which is an option on the DP-63S. Both can handle paperweights from 13 lb. to 110 lb. and sizes to 11.88x17.28˝.
Ricoh Corp. is a player in both markets. Its Aficio Color 6000 series of professional copiers is capped off by the model 6513, which prints 13 color pages per minute (51 ppm in black-and-white mode). It handles stock sizes up to 13x19˝ and weights to 140-lb. index. The firm's duplicator product family is headed by the Priport JP800 and VT6000. Both handle stock sizes to 12.5x17.5˝ and output 120 ppm at 600 dpi.
Setting aside the advances in digital interfaces, the fundamentals of these print engines remain largely unchanged. However, a couple of new technologies and systems have been introduced that reengineer the imaging process itself.
Several years have passed since its original introduction, but the Océ CPS700 color printer (and copier) reportedly is now commercially available. The unique feature of the device is its use of seven-color imaging—CMYK+RGB—in one pass. The company says seven colors are used to improve the printer's color stability and accuracy, not increase its color gamut. The machine prints 25 ppm on stock weights up to 110 lb.
