Federico D'Annunzio, Programme Manager of joint BOBST - Mouvent Hybrid Label Presses comments, “The real differentiator is that you only have 30 grams of ink in the whole print unit. When you wash it, in terms of sustainability, waste is vastly reduced. In other systems you use litres and litres of washing liquid every time you wash the print unit. We are using grams.”
“Secondly, with our system there is no direct hand contact for the operator. It is a system for the new generation of operators who are highly skilled, and it allows the possibility to have a new level of operators on the machine. The solution gives more time to manage data and work with digital methods.”
“It’s also easier to substitute with a new ink with DigiColor. It allows to control the ink while printing on a flexo machine without changing the anilox roller. We can provide colour consistency to brand owners with this solution.”
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.
The BOBST DigiFlexo presses in demonstrations were equipped with all the latest technologies developed by the REVO partners: patented GTT 2.0® anilox rollers by Apex International delivered consistent ink laydown for uniform color consistency; workflow automation on color and register by AVT guaranteed digital control of color and print quality and on-the-fly adjustment capabilities; flexo plates by DuPont enabled 120L/cm print quality.
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 1000sqm 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. From the new file, in just one hour, it is possible to print the new job on press including plate making, plate mounting and press set up.
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.
As one brand owner put it seeing his jobs printed live in front of him, “You’re spot on!”. Converters were very impressed with the uniquely high production speeds of 100 m/min reached during the live demonstrations, without compromising on the 1.200x1.200 Lpi print quality of Mouvent digital Inkjet heads. Instant job changes and especially real-time live customization left attendees amazed.
“It was a great opportunity for us to present the unique features and simplicity of our digital solutions to such a high class audience, and the strong interest shown by visitors is the best sign that we’re on the right track with our offer,” summed up Reto Simmen, Mouvent’s Chief Business Officer.
In a nutshell, the Label & Packaging Innovation event demonstrated how digitalization, automation and connectivity help converters to better serve their clients.
BOBST will be present at Labelexpo 19 in Brussels to continue the industry transformation.
