Italian label printer Grafiche Quartana has installed UV Ray’s Atom mercury arc UV and MaxLED water-cooled LED curing lamps on its Omet iFlex label press.
The Matera-based, family-owned company produces high-quality food, wine, and cosmetic labels at a 2000sq/m label production facility.
Owner of Grafiche Quartana, Marco Quartana stated, ‘We chose to mount UV Ray lamps from the beginning, as we find they are a streamlined company with an advanced technical product that reflects the customer’s requirements and provides a customised product when necessary.
‘LED curing systems were mounted on the machine in line with energy savings, but also for their reliability. In our case, the system fits well with the high performance of the Omet iFlex, which is among the most advanced in the industry.’
The Omet press is a 360-format, 8-colour flexo press with a reversing bar, cold foil, and inline die-cutting with rotary cylinders. It was installed at Grafiche Quartana in July 2023. UV Ray said three of the press’s units are equipped with hybrid mercury arc/LED curing capability, while the remainder are LED only.
Alberto Maiano, CEO of UV Ray, explained, ‘Water-cooled LED technology is well-suited to Omet’s single-pass flexo presses. Combined with the iFlex print quality, it allows for the best results in every respect – especially register accuracy even when printing on sensitive and difficult materials like thermal paper or plastic films such as clear-on-clear.
‘Furthermore, there is no heating of the press or its parts, including the die that collects all the material temperature at the end of the press.’
He added that the water-cooled nature of MaxLED is essential for maintaining running temperatures on press with difficult materials such as those mentioned, as well as for keeping the LED in good working order.
