In the early days of digital printing, there were few options in terms of digital finishing equipment. Tasked with keeping pace with manufacturers of digital presses, digital finishing equipment providers have expanded in number and risen in quality. What follows is a description of available digital finishing equipment and the recent developments made by key suppliers in the industry.

AB Graphic International
Bridlington,UK-based AB Graphic International Ltd. launched new label converting lines and an array of options at Labelexpo, which are designed to increase productivity and simplify operation on both its new and existing product range.

The new Omega SRI label inspection rewinder was the centerpiece of the company’s exhibits. The rewinder uses the latest servo drive technology in combination with PC/SPS based controls, resulting in what the company describes as “a new level of sophistication and productivity” and enabling rewind speeds up to 350m/min. A new ergonomic design permits operation either sitting or standing and all in one choice of finishing in either the horizontal or vertical position. The system includes FleyeVision print face inspection through the same touch screen as the machine. Removal of waste is carried out under full control and during the process the camera is still inspecting.

For flexible packaging converting, the company has worked closely with press manufacturer Edale to develop a 30” finishing line for digitally pre-printed label and flexible packaging substrates. The system is designed for short runs and can be supplied to complement any 30” wide digital press installation to enable finishing through a wide range of converting options for PSA labels as well as laminating and decorating for flexible packaging.

The new Digilase laser label cutting system also debuted complete with the company’s digital die shop software enabling users to import, create or edit die patterns through the familiar Adobe Illustrator plug-in platform. The system permits each job to be tested in a virtual machine environment, including estimated maximum run speeds before going live. Latest developments allow a totally automated creation of the laser cut file that is normally created manually for every new shape. Key benefits versus conventional diecutting include no-tooling and associated storage requirements and no waiting for delivery times.

In combination with its new product range was the launch of JDF/JMF software that is available on a variety of the company’s products, including the Digicon and Omega brand converting lines as well as on the Digilase system. The software connects the equipment with
the pre-press MIS system and increases productivity through enabling automatic set-up of job parameters and offers real time feedback from the finishing line. The JMF software assists with production management and enables information to be sent back from the finishing line to the MIS system including details of material waste, machine status, label count, web speed and set-up times.

An array of new options include auto-slitting through HMI interface to reduce knives set-up times on the Digicon and Iscore system for automated back scoring. The new Vectra combo turret rewinder also is equipped with new contact matrix stripping, automatic core loader and new glue bath system.

Rotoflex
For more than 40 years, Rotoflex has provided offline finishing products to support many printing processes. And while Rotoflex experienced success in finishing digitally printed materials - most notably with the Vericut product produced until 2010 - the R&D and engineering teams have taken the proliferation of digital printing products and the increasing demand for equipment to finish these materials as an opportunity to reevaluate their offering to truly support converters’ changing needs.

According to the company, shortfalls are evident in the offline finishing products currently available to the market. Suppliers are not able to keep up with current demand and converters need these finishing technologies to support superior inspection with faster setups and changeovers, at productive speeds, optimizing their turnaround and profitability.

“Rotoflex is actively designing a new rewind platform to be available globally in early 2014, which will address the ever-changing inspection rewind requirements to maximize digital workflows and shorter run capabilities,” says Rotoflex Business Director Kevin Gourlay. “Both full- and semi-rotary capable, and able to incorporate a variety of finishing processes including lamination, hot and cold foil, screen and coating (both full and register spot), this servo-driven machine will include the exclusive Rotoflex eDrive web transport system to produce finished rolls of superior quality.”

Mark Andy
According to Jeff Feltz, director of business development at Mark Andy, when digital printing first came into the label and package printing space, attempts were made to combine digital with traditional full rotary converting designs. After some failed attempts by press manufacturers, the market maintained that offline converting was better suited for the type of digital workflows of the time.

“There were many aspects that caused in-line rotary converting to fail,” Feltz says. “Some of the early (and still existing) digital solutions did not print a consistent output between repeats or frames, making full rotary converting nearly impossible, even with advanced servo registration systems. The short run lengths produced on digital devices could not economically support the workflow of a traditional rotary die. And traditional die station technology was very cumbersome to set up, reducing the effectiveness for shorter runs.”

Recent developments are changing this perspective. First, the speeds of recently launched inkjet systems, like the Mark Andy Digital Series, are upwards of 250 fpm. At these faster production speeds, and with modern in-line rotary converting, a fully integrated platform is now attainable. Repeat-to-repeat consistency is very good, the company says, allowing rotary dies to easily maintain registration to the digital print at production speeds. Secondly, the popularity of magnetic cylinders and flexible dies has significantly reduced costs. Finally, advanced-design die stations like the Mark Andy Quick Change Die Cut (QCDC) with single minute changeovers, now match up well with combination digital/flexo printing platforms. As digital moves to a more production-level process, in-line converting makes absolute sense and is being enabled by new advances in converting technology, according to Feltz.

Primera technology
Headquartered in Plymouth, MN, USA, Primera is a specialty printer manufacturer whose products are sold worldwide through Primera-authorized resellers and distributors in more than 179 countries.

For the digital finishing market, the company offers the FX1200. It is an off-line label production machine designed and manufactured by Primera.  The FX1200 accepts up to 12" (305mm) O.D. (Outside Diameter) rolls of printed output from digital label presses such as Primera’s CX1200 Digital Color Label Press. It finishes the printed output with several different operations including:
 
 Lamination – with clear polypropylene (PP) or polyester (PET) films for increased durability and UV resistance
 Digital diecutting – in any size or shape
 Waste matrix removal – making finished rolls ready for use
 Slitting – for making multiple narrow rolls from the wider input roll
 Rewinding – onto multiple 3" (76mm) O.D. cores
 
Utilizing Primera’s patent-pending QuadraCut technology, virtually any size and shape of label can be produced including complicated contour cuts, without the need to purchase expensive rotary or flat dies. Up to four cutting blades can be installed at one time to quadruple the speed compared to competitive machines that use only a single blade.

“After introducing our groundbreaking CX1200 Digital Color Label Press, we discovered that the few existing finishing systems available were not fast enough, not reliable enough and not easy enough to use. So, we built our own,” says Mark Strobel, Primera’s vice president of sales and marketing. “The result is the FX1200. There’s nothing else that compares to it for even four or five times the price.”
