The DigiFlexo innovations presented by Bobst and its 12 REVO partners, along with Mouvent digital inkjet printing, fulfilled brand owners’ needs and solved converters’ challenges. “The game-changing solutions will set a new course for the industry’s future," said Stephan März, head of Business Unit Web-fed, Bobst Group “Bobst innovates and collaborates with premium partners in labels and packaging. This helps us to be agile and proactive towards the fast changes happening in our industry."
"The number of working equipment on-show was impressive. Visitors could participate in hands-on demonstrations of inter-linked equipment and complete workflows," added Dan Pulling, EMEA business development manager HD Flexo & Color at Esko.
Each of the event’s three main themes of time-to-market, color consistency and food packaging safety was presented to visitors. Live demos showed how to achieve labels and packaging production faster, consistently, safely, and with a reduced use of resources via new design concepts, workflows and use of digitalization.
Bobst introduced two products relating to flexo inking and color matching: Ink-on-Demand (IoD) and DigiColor.
- The IoD inking system replaces conventional inking reservoirs with a single rubber pipe that dispenses 30 grams of ink to the print unit. The system eliminates ink trays and chambered doctor blades.
- DigiColor, the solution for REVO Extended Color Gamut (ECG) printing takes the IoD concept one step forward: the hue of the ink dispensed to the print unit can be digitally adjusted by mixing a darker and a lighter shade of each color in the proportion required to match the target Delta E value during printing. The digitalization of the process gives converters and brand owners the certainty of matching Delta E at any speed, on any substrate, with any operator, anywhere in the world. The IoD and DigiColor technologies were demonstrated on a Bobst M5 DigiFlexo press.
- Closed loop and traceability on Bobst DigiFlexo technology was a world premiere. It combines Esko WebCenter platform managing production specification, approval and project life cycle, X-Rite ColorCert color communication system, AVT SpectraLab inline spectral measurement and monitoring, and PantoneLive digital brand color management assets. It is a fully digitized and connected workflow enabling the traceability of every item of packaging, from the original file, to the press, to job validation and storage of the digital data generated from the final printed job. This solution was presented live on an M6 DigiFlexo Press for flexible packaging.
A range of new technologies addressed the safety of food packaging. The new generation of low migration UV inks by Flint Group integrated into the REVO process, provides food-safe compatible printed samples. These are certified by the UV monitoring system by GEW, which allows the unique safety traceability of every meter of printed substrate.
UPM Raflatac introduced new food label substrates that support product safety and legal compliance.
According to Michael Paulin, factory manager, Lexit Group, Sweden, “It was a dream come true with REVO. Now we are able to print a difficult CMYK and Pantone label, knowing that the result will be the same in the printing press as the proof.”
“Our jobs set up very quickly, and the colors hit our customer signed-off Match prints most every time.
For repeat work, our consistency is exceptional from run to run,” said Paul Polewko, Production Manager and Technical Director, Revere Group, USA.
At the event, visitors discovered the recently opened REVO Academy, installed in Bobst Firenze’s new 1000 square meter Competence Center. The equipment encompasses the Esko Crystal CDI 4835 XPS ECG separation and imaging and Kongsberg X20 cutting table, and X-Rite I1Io scanning table. The REVO Academy is open to converters worldwide to test and get trained on the turnkey ECG solutions.
Mouvent, the digital printing competence center of the Bobst Group, presented its LB702-UV high productivity digital label press in a 6-color set-up (CMYKOV) for the first time, showcasing digital ECG and spot color printing matching DigiFlexo ECG colors.
