Medium pressure mercury arc UV lamps have been the mainstay UV curing technology for printing processes such as offset, flexo, screen, digital and others for many years. UV LED curing technology is gaining traction due to its much longer operating life, instant on/off capability, and reduced maintenance time which combine to improve press productivity compared to traditional arc lamp UV curing. In fact, flexo label and tag producers using UV LED curing report significantly faster press speeds compared to arc lamp UV curing. Read more about the benefits of UV LED curing for flexo processes .
When retrofitting flexo presses with UV LED curing it’s important to understand which product features matter most for delivering reliable and high capacity label printing and converting processes. To deliver the highest press capacity and production rates, the UV LED solution you choose needs to provide the fastest speeds and the most reliable and consistent curing results. And with the trend toward smaller print runs, minimizing changeover time between print jobs is another critical factor.
