Not a week goes by that we don’t hear of another digital printer manufacturer making the switch to LED curing technology for ultra-violet (UV) inks.
In the digital printing arena this is most commonly for wide format digital print engines. UV-curable inks stick to pretty much any nonabsorbent substrate including paper and board, wood, PVC, glass, metals and ceramics. They produce minimal VOCs so they don’t need expensive exhaust systems.
The arguments in favour of using LEDs instead of conventional mercury arc curing systems for UV ink curing get more compelling as technology advances and as more developers follow EFI’s lead and go for the LED alternative.
