GEW launches LeoLED

GEW, which develops UV solutions, will be showing its next generation UV LED system, LeoLED, at the upcoming LabelExpo show in September.

GEW has developed this UV LED cassette, the LeoLED.

It’s designed to be retrofitted to conventional presses to allow them to run with UV-curable inks. The new LeoLED has a number of advantages, including a 50mm wide window for a longer dwell time. It’s also sealed against water for easier cleaning, and is said to be resilient to dust and ink ingress. It has an integrated water-cooling system and delivers electrical power at 88W/cm and an intensity of 25W/cm2, with minimal light loss due to the direct UV path. 

It comes in a cassette, which is compatible with the existing ArcLED system and should make it easier for users to upgrade from one to the other. There’s also a more compact option for very confined spaces, and for sheetfed offset presses. It comes with a 5-year GEW system warranty.

As with the ArcLED system, it can be used with either a conventional UV arc lamp or LED array on the same print unit, with both arc and LED cassettes being compatible with the same power supply and fitting in the same housing for ease of change. GEW also sells a Rhino control unit that allows  any combination of curing technologies to be used on the same press to  suit process requirements and ink formulation.

GEW will also use the LabelExpo show to demonstrate its E4C mercury arc lamp system. E4C is the highest powered lamphead in the GEW mercury arc range and can deliver up to 200W/cm, making it also suitable for Low Migration food packaging applications. It is also fully compatible with GEW’s ArcLED hybrid system.

GEW will also show off its multi-point UV monitor, which offers a reliable and cost-effective solution to ensure that curing has been completely effective. You can find further information from
