New test device to identify the quality curing level of printing inks

摘要

Determining the curing degree of UV inks poses a challenge to press operators around the world.To solve this problem,hubergroup,one of the leading international specialists for printing inks,has invented an innovative technique:”NewV cure”.While UV inks are gaining popularity and offer a high-speed curing process,it has been difficult to quickly and definitively determine whether the print is properly cured.Due to the lack of reliable methods,most operators check curing quality subjectively using physical tests such as wiping,scratching,or a thumb,as well as chemical characterization.However,the curing degree affects hardness,robustness,migration behaviour,and the ability for further processing of an ink film-in effect,improper curing negatively affects the usability and quality of the printed product.
