Drying, Curing & UV
UV LED curing charts a new course for print innovation
UV LED curing has built up strong momentum in recent years as a key strategic choice for the label and narrow web sector. This technology, once seen as a niche alternative suitable only for certain applications, is now redefining what is possible in narrow web printing, says Marc Heylen, global R&D and technical director narrow web at Flint Group.
C
onversations are shifting towards how UV LED curing can unlock untapped potential in quality, operational fl exibility and market expansion – and
increasingly, sustainability. Off ering a fundamentally diff erent approach to print production, UV LED brings consistency, reliability and new creative possibilities into the pressroom. By delivering instant on-off switching, uniform output and minimal heat radiation, these systems enable printing on a wider range of substrates such as heat-sensitive fi lms and shrink sleeves, with greater control and fewer restrictions.
The speed and precision of UV LED curing are also driving creative advances, off ering particular benefi ts for the premium labels market, where capturing fi ne details and vibrant colours are essential to brand identity. The precise control that UV LED off ers over curing parameters enables further customisation, tailoring the process for each job to optimise adhesion and performance. The result is not only improved print quality but also enhanced durability, with labels that resist scratches, moisture and other incidental damage. Beyond quality and productivity, UV LED curing delivers signifi cant sustainability benefi ts. UV LED systems are markedly more energy effi cient than conventional UV lamps, translating directly into lower operating costs and smaller carbon footprints for printers. UV LED units also do not contain mercury, eliminating the need for special handling or costly waste disposal and resulting in safer workplaces and communities. Additionally, the long operational life of LED lamps – often multiple times greater than UV alternatives – means fewer replacements, less downtime and even further reductions in waste. By eliminating lengthy heating and cooling cycles, this technology also minimises turnaround times and enables converters to respond rapidly to market demands for short runs and fast delivery. This agility is crucial as brands increasingly seek

innovation shows no signs of slowing. Advances in photoinitiator chemistry, the emergence of bio-renewable resins and the ongoing refi nement of UV LED lamp technology, all point to a future where converters will have an even broader toolkit at their disposal. For those willing to embrace these trends, the rewards include not only improved operational performance but also the ability to off er customers greater choice, quality and peace of mind.
personalisation, seasonal promotions and regional variations in their packaging.
However, the adoption of UV LED remains under careful evaluation. Many converters are understandably cautious, weighing the risks of moving from tried-and-tested UV Hg lamps to investing in UV LED equipment. The market is still in a period of hybridisation, where both UV Hg and UV LED technologies often must coexist on the same production fl oor.
This landscape is where dual-curing ink technology shines. Flint Group’s EkoCure Dual Cure is a standout solution, engineered to cure seamlessly under both UV Hg-based and UV LED lamps. This unique fl exibility empowers converters to upgrade at their own pace, future- proofi ng their investment while maintaining high performance and reliability across both curing platforms. With EkoCure Dual Cure, converters can streamline inventory, reduce waste and avoid costly downtime, all while delivering consistent, high-quality results to their customers. Looking ahead, the momentum in UV curing
Digitalisation and automation are further accelerating the transition to UV LED. The integration of AI-supported process control systems is helping converters optimise curing parameters in real time, improving consistency and reducing waste. At the same time, data- driven insights are enabling printers to monitor lamp performance, anticipate maintenance needs and extend equipment life – factors that are becoming increasingly important as production runs become shorter and more varied.
To accelerate adoption and begin reaping the benefi ts of UV LED more quickly, collaboration across the print value chain will be essential. Ink and equipment suppliers, converters and brand owners are working more closely than ever to share knowledge, develop tailored solutions and ensure that new technologies deliver tangible benefi ts on the production fl oor. Industry forums, technical workshops and joint development projects are becoming the norm, fostering a culture of innovation and continuous improvement. With the label and narrow web sector navigating a dynamic period of innovation in UV LED curing, staying attuned to trends and fostering collaboration will be instrumental to success. For those ready to write the next chapter in their UV curing journey, the message is clear: with the right support and the right technology, the possibilities are limitless.
