Overcoming challenges of LED in graphic arts applications

Anna Johnson, Sartomer

Abstract:Advantages of LED over conventional UV lamps for graphic arts applications are well documented but this shift in technology has introduced new challenges. While LEDs reduce operating costs and have a smaller environmental footprint, the ongoing market challenge for LED is the limited emission spectra which leads to lower surface cure. This presentation includes an overview of current technology and novel solutions being developed for overcoming low surface cure.
