Digital Finishing : Taking Their Output Off-line
An operator at Publishers’ Graphics keeps pace with a Standard Horizon BQ-470PUR perfect binder, which produces lay-flat books.
Hearty finishing equipment was acquired by Publishers’ Graphics to handle work produced on digital devices such as the Xerox iGen4 press, shown here.
The variability of work is the wild card element when it comes to finishing in-line, off-line or near-line in a digital printing environment. More and more, it seems some in the printing community are leaning toward off-line finishing, which could be a long-term trend as opposed to fashion du jour.
As printers become more specialized, it makes the in-/near-/off-line decision making process clearer. Turnover times and run lengths continue to shorten, but the need for quality hasn't been compromised, prompting many printers to take their finishing functions off-line.
One printer with a focused specialization is Arvato Digital Services, with a division that specializes in supply chain management for the healthcare industry, especially pre- and post-enrollment materials, which are saddlestitched or perfect bound and combined with various other printed collateral.
"Our page counts fluctuate dramatically from piece to piece," notes Todd Potrykus, director of print-on-demand for Arvato Digital Services. "We take care of a lot of the production management by systematically setting them up for gang runs based on similar page counts. We have to make sure, from our saddlestitching needs, to our perfect binding needs, that the equipment we have is able to change quickly or change on-the-fly to handle the variable page counts."
Among Arvato's finishing gear are three Standard Horizon StitchLiner 5500 stitchers, a Standard BQ-270C perfect binder and a BQ-470 perfect binder. The company recently acquired a Muller Martini Sigma perfect binder, which is actually a near-line machine. Their commonality—the ability to bounce back and forth from page counts of 100 to 300 to 250, wherever the customer need takes Arvato.
"A big advantage of (the Sigma binder) was the ability to change on-the-fly," Potrykus says.
On the digital printing end, Arvato Digital relies on four Océ continuous-feed machines—three VarioStream 7650s and a DemandStream 8090—along with two cut-sheet Océ 6250s.
