KELENN at UV Days: Closing the Inkjet Credibility Gap
Inkjet printing has long promised a digital future for industrial production, yet the transition from analogue remains incomplete: there still seem to be ongoing concerns around quality, reliability, and system integration. At IST UV Days in Metz , Didier Rousseau of KELENN Technology, joined the 'Evolution of Inkjet' conference hosted by Frazer Chesterman of FuturePrint and Holly Steedman of IST Intech to outline how it is tackling these barriers head-on, with a platform engineered not to retrofit inkjet, but to industrialise it.
Specialising in high-performance digital print systems, KELENN doesn’t just bolt inkjet onto legacy workflows—it reimagines inkjet as a digitally native manufacturing process. One that matches analogue for consistency while opening up new levels of automation and agility.
At the centre is a closed-loop architecture that integrates inkjet print engines, advanced drive electronics, RIPs, and real-time vision inspection, all linked to a fully digital front end. This is active process management, rather than just quality control. High-speed cameras—such as KELENN’s KV+ module—detect missing nozzles, colour shifts, stitching errors or data mismatches within milliseconds. The system then adjusts waveform parameters, corrects layouts, and resumes production—automatically and without intervention.
This real-time feedback architecture enables more than just improved output—it delivers near-zero setup time, full variable data integrity, and traceability. Through KELENN’s Print Flow platform, OEMs and integrators can deploy at multiple levels: from low-level API access and hardware abstraction layers (via the Smart VDG and KPC modules) to full turnkey systems with user-friendly interfaces powered by KRIP and Smart KPM.
To reduce downtime, KELENN has developed a proprietary ink recirculation system—simpler and more robust than conventional solutions. With its modular drive electronics, the platform supports high-resolution, page-wide printing on a wide range of substrates, including PET films and synthetic papers. Whether running UV or water-based inks, it guarantees precise drop placement, long maintenance intervals, and seamless synchronisation with upstream processes.
One of the most striking implementations is KELENN’s inline pouch printing system. Here, variable data is printed directly onto packaging materials during production—eliminating labels, pre-printed rolls, and manual changeovers. This means: reduced setup times, simplified logistics, and late-stage personalisation with no compromise on speed or quality. In real terms, this system has delivered productivity gains of up to 40%.
KELENN’s proposition in a nutshell: inkjet should not just be flexible—it has to be industrial. Its machines don’t just print; they observe, adapt, and self-correct in real time. As sectors from packaging to printed electronics demand smarter, shorter-run, and data-rich production, KELENN’s model shows: digital print succeeds not by being novel, but by being dependable.
