UV inks are gaining popularity for packaging printing due to their high-speed curing process, which enables further processing near instant. Up to now, it has been difficult to quickly and definitively determine whether the print is properly cured and so printers have been using subjective methods. However, since the curing degree affects hardness, robustness, migration behaviour, and the ability for further processing of an ink film, improper curing may negatively affect the usability and quality of the printed product.

A team of hubergroup employees dedicated itself to this problem and invented an innovative technique called “NewV cure”. Dr Carina Sötebier, Head of Central Analytical Lab at hubergroup and project lead for NewV cure, explains: “To determine the curing level of UV inks, we use a test liquid and an electronic test device. By testing a predefined extract, NewV cure can then identify the quality level of a printed product. Our new, science-based approach provides an easy and objective evaluation of UV curing within a few minutes. ”

Roland Schröder, Product Manager UV at hubergroup, adds: “With NewV cure, we end all subjective methods of curing determination and create a new standard for quality management in UV curing. It will help to reduce waste and rejects due to incomplete curing and increases security in packaging production.”

As our previous tests with NewV cure were very successful, we will present first results with this new method to IST UV Days attendees in Nürtingen, Germany, on May 13 to 16. We are looking forward to meet you at the event!
