LED-UV becomes more and more important. This technology combines all advantages of traditional UV printing; however - compared to conventional lamps - without the emission of ozone or the use of mercury vapor lamps.
Although there may be limited need for additional protection of the printing image due to the immediate curing of LED-UV inks, overprint varnishes are indispensable (especially if the printed product is taken in hand regularly). They finish with valuable visual effects and differentiate the brand from competition. Moreover, LED-UV coatings provide a wide range of advantages, as for example a high reactivity, the very good mechanical resistance or the fact that they can forgo the use of anti set-off powder for optimal surfaces.
