LeoLED Standard

Transform your press with a GEW LeoLED UV system, the most effective curing technology for sheetfed offset printing.

LeoLED Standard

GEW’s LeoLED has a unique concept: deliver more UV dose for your money than any other product available. Over 5 years of product development & the latest LED technology combine to transform the economics of UV LED curing. Fully water-cooled, LeoLED provides over 35% more dose and 40% higher irradiance than GEW’s previous LED models.

LeoLED Standard is water-cooled with a compact 40x100mm profile while extensive customisation integration is available to ensure our system fits your press. Furthermore, the system has a large window which allows for maximum light extraction from the lamp and delivers maximum UV dosage to your substrate.

Like all our UV products, LeoLED is powered by GEW’s RHINO power supply which uniquely allows GEW customers the flexibility of ArcLED without having to invest in a new independent power system. It is also controlled by RHINO control which comes as standard with IoT remote monitoring for the fastest most effective service response in the industry.

Also available in a Cassette version, LeoLED Standard is perfect for sheetfed offset machines and can be manufactured from 15cm to 170cm, with multiple lampheads being used in tandem where greater curing widths are required.

Benefits of LeoLED Standard

  • Print on plastics – UV LED polymer inks allow successful printing on almost all stock types.
  • Sharper dots and vibrant colours – GEW’s LEDs achieve sharper dots, more vibrant colours and a better quality finished product.
  • No more marking and scratching, no more sealer – UV LED inks and varnishes are 100% cured directly after the LED lamp. As inks are dried instantly, marking of sheets in the delivery or during the perfecting process is eliminated.
  • Instant drying for faster job turnaround – Instant drying of inks enables immediate finishing and much faster despatch of jobs.
  • 100% UV uptime – The printer never waits for the UV lamps because GEW’s LEDs’ instant on-off switching means no warm-up or cool-down cycles.
  • No heat – Unlike H-UV or traditional mercury lamps, LEDs emit very little infrared heat towards the substrate.

Modular Lamp Array (MLA)

LeoLED’s Modular Lamp Array offers the ultimate in flexibility and enables GEW to deliver the highest energy dose in the market, at the best value.

All lamps on the press have identical design and can be freely moved between print stations to change curing configuration and adapt to the job at hand. For highly demanding applications (such as B1 LED coating at 18,000sph) multiple lamps can be placed in tandem at the end of the press.

One of the key benefits of the LeoLED UV curing system is its ArcLED capabilities.

ArcLED’s power system allows the printer to switch seamlessly between mercury arc technologies and LED technology.

Since its humble beginnings in 1989, Martin One Source has greatly expanded its business, its product range, and its customer base. The company is now a one-stop print supplier with a comprehensive product portfolio, servicing businesses across the Midwest.

The company’s commercial printing work has grown exponentially in recent years and a GEW LED UV curing system has been installed to keep pace with demand.

The management team had heard about the supposed advantages of LED UV and were particularly interested in the potential energy savings and other environmental benefits. Power usage was a key deciding factor and the energy savings have since been realised. Doug Brady, VP Operations, explains: “Our old UV press accounted for 33% of our total utility bill for our entire plant. By removing that and putting in the LED system, we average savings of about $40,000 a year just in power consumption.”

CEO Chuck Martin sums up his thoughts on LED UV and its future at Martin One Source: “Now with all the efficiencies and the economics of the LED UV, we would never go back to the conventional UV… we will be LED UV users from here on out.”
