HP Indigo unveils two new digital presses

September 28, 2011

The new WS6600 digital press includes a priming unit for pretreatment of substrates.

HP took the wraps off its latest digital print products, the HP Indigo WS6600 and the WS4600 digital presses. The 6600, the second generation of the WS6000, is capable of printing more than 40 linear meters (131 feet) per minute in full color, and features a new inline priming unit. The WS4600, an evolutionary step in the 4000 series, has an option for full color throughput of more than 21 meters per minute (69 feet) per minute. Both new presses deliver higher throughput via a new Enhanced productivity Mode developed by HP.

“With the Indigo WS6600, we can produce jobs of over 10,000 linear meters with the outstanding quality that our customers are demanding, and still deliver fast turnaround,” said Roger Gehrke, executive manager of digital printing at Rako Etiketten in Wizhave, Germany. Rako is a beta user of the 6600.

For many CMYK jobs, HP’s Enhanced Productivity Mode increases throughput on the WS6600 by more than 30 percent, the company says, increasing the crossover point with conventional printing by up to 50 percent. The press also supports a white ink mode that provides high opacity and continued productivity, giving converters the ability to print at standard multi-color throughput levels. The 6600’s priming unit treats substrates with the coating required for printing on the press.
