Integrating with narrow web presses, GEW ArcLED Hybrid LED UV System can consistently cure heavy inks with optimized adhesion. Conventional arc lamps can be combined and interchanged with LED curing at every print station. Same lamphead casing is used with interchangeable pull-out cassettes for arc and LED, including same power supply and control. Associated RHINO-ArcLED power supply automatically recognizes type of cassette being used and adapts all parameters accordingly.
