GEW to Launch LeoLED UV Curing System at Labelexpo Europe 2019
LeoLED represents the next generation for LED UV curing and is set to have a significant impact in this highly competitive market. In LeoLED, the technology has been redesigned and refined for simplicity and offers excellent value, while at the same time delivering maximum power and dose of UV energy. The LeoLED cassette is fully compatible with GEW’s ArcLED hybrid system and brings LED UV within affordable reach for all.
The leading-edge design of LeoLED brings several new benefits: the 50mm width window gives a long dwell time and is waterproof-sealed for easy cleaning. It is also resilient to dust and ink ingress. The LED array delivers electrical power at an impressive 88W/cm and an intensity of 25W/cm2, with minimal light loss due to the direct UV path. Furthermore, the integral water-cooling system gives LeoLED the ultimate operating capability and reliability in its class.
The new lamphead is built to GEW’s usual exacting standards, using state-of-the-art manufacturing techniques, for robust performance and reliability. It is also offered in an alternative, more compact configuration for very confined spaces, and for sheetfed offset presses. All formats can be easily retrofitted to almost any press and are available with a 5-year GEW system warranty, for peace of mind.
ArcLED Hybrid Compatibility
The LeoLED system employs ArcLED hybrid UV technology, which allows the use of a conventional UV arc lamp or LED array on the same print unit. Both arc and LED cassettes are compatible with the same power supply and fit in the same housing for ease of change. GEW’s RHINO control enables any combination of curing technologies to be used on the same press. ArcLED enables the printer to switch between arc and LED UV curing at will, to suit process requirements and ink formulation.
Alongside LeoLED, GEW will feature the latest mercury arc lamp technology, including its compact E4C system. E4C is the highest powered lamphead in the GEW mercury arc range and can deliver up to 200W/cm, to support the most demanding UV curing operations. E4C performs to the harshest cure test procedures and is suitable for Low Migration applications. It is also fully compatible with GEW’s ArcLED hybrid system.
GEW will also showcase its multi-point UV monitor (mUVm), which has been shortlisted in the Innovation category for the Label Awards 2019. Multi-point UV monitoring is increasingly used to attain 100% UV inspection and to generate a UV curing certificate for every printed batch, by recording live outputs for every lamp. The monitors provide a highly reliable and cost-effective solution to eliminate the risk of under-cured product reaching the customer, when used as part of a Good Manufacturing Practice procedure.
