UV LED … what’s it all about?

UV curing has traditionally been accomplished using mercury-vapour lamps but with the advent of LEDs capable of producing UV radiation, curing devices using LEDs are increasingly found in printing applications.

One name that’s at the forefront of any discussion on UV LED curing technology is Phoseon Technology. The company has been developing UV LED technology since 2002.

According to Phoseon, UV LED curing systems allow printing of high-quality materials at maximum speeds. For label printing, it shows measurable advantages  in high productivity, low energy usage, reduced heat load for thinner substrates, and clear environmental benefits. Being solid-state devices, LEDs offer instant on/off with no warm-up time and without ozone creation there’s no need for air ducts or ventilation.

One name that’s at the forefront of any discussion on UV LED curing technology is Phoseon Technology. The company has been developing UV LED technology since 2002.

Phoseon’s FirePower line allows increased speed in flexo printing. The intense UV output (up to 20W/cm2) paired with UV LED flexo inks have achieved record press speeds. The low heat output of the FirePower has enabled new capabilities such as heat-sensitive materials, unsupported films and thinner substrates.

When it comes to press suppliers, Mark Andy has been a trailblazer in adopting the technology, working in partnership with Phoseon Technology to develop UV LED curing for its narrow-web presses.

Dedicated UV LED inks are a necessity and ink makers have been busy developing suitable products. One is Flint Group Narrow Web, offering its award-winning EkoCure UV LED flexo ink technology. Since gaining this enviable recognition, EkoCure inks have become globally available and include products for rotary screen whites, various coatings and adhesives, and flexo shrink whites. Scotland’s Paragon Inks has also been busy
in this market and has released a low-migration LED range.
