  • GEW ArcLED Hybrid UV Curing Systems

    TWO UV Curing Technologies
    ONE RHINO Power Supply

    ArcLED allows use of a conventional UV mercury arc lamp or  LED (light emitting diode) 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.

    The RHINO control enables any combination of curing technologies to be used on the same press.

    Future proof UV technology

    GEW arc and LED systems can both be upgraded in the field to the hybrid solution or be supplied in this configuration from new.

    ArcLED enables hybrid, interchangeable UV curing on every print station, allowing the printer to use a combination of arc and LED technology seamlessly on the same press and to switch between arc and LED curing at will to suit process requirements and ink formulation.

  • GEW E2C UV/LED Curing System

    GEW’s E2C is the most powerful low energy UV curing system for narrow web presses.

    The E2C UV curing system with RHINO electronic power supply takes curing of inks and coatings to new levels of productivity and print run security. The E2C-RHINO systems use substantially less energy. They enable colour process printing at full production speed with as little power as 90 W/cm (230W/inch).

    E2C UV curing systems are safe for the widest range of heat-sensitive materials with no heat transfer to the machine or substrate at stand-by through the use of actively air cooled shutter technology.

    E2C systems are available with inert atmosphere curing. They can easily be upgraded to LED curing by using the same RHINO ArcLED electronic power supply.

    Where alternative products exploit conventional curing technologies that often neglect energy monitoring, GEW state of the art UV systems implement advanced UV lamphead technology associated with the most energy efficient power supplies. E2C RHINO systems come with the additional benefit of a comprehensive 5-year warranty unique in its industry.

  • GEW LW1 LED UV curing system

    GEW’s patented LW1 lamphead is the most effective water-cooled LED UV curing technology on the market.

    ArcLED hybrid UV technology

    ArcLED allows 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. The RHINO control enables any combination of curing technologies to be used on the same press.

    Futureproof LED UV curing technology

    ArcLED enables the printer to switch between arc and LED UV curing at will to suit process requirements and ink formulation. GEW arc and LED systems can both be upgraded in the field to the hybrid solution or be supplied in this configuration from new.

    Double production speeds with thick, heavily pigmented inks

    LEDs’ high intensity UVA radiation penetrates thick ink layers for more consistent curing with improved adhesion, delivering faster speeds with silkscreen, laminating and flexo base white.

    GEW LED UV curing systems are compatible with the widest range of substrates

    Even unsupported films, shrink sleeves and other delicate, heat-sensitive materials can be processed without heat damage or registration loss thus eliminating the need for chill rollers, as nearly all heat generated by the LED array is conducted away to the rear heatsink, with almost pure UV radiated towards the substrate

    Increased machine uptime

    Instant on/off switching means that with LEDs there is no warm-up or cool-down cycle due to the simple switch and go technology of LEDs.

    LED arrays require less frequent maintenance as they last over 20,000 hours (between 5 to 7 times longer than a typical GEW E2C UV arc lamp). Because LED systems have no moving parts, there is no downtime to replace shutters, reflectors, mechanisms or lamps.

    No ozone, no mercury

    GEW LEDs produce no ozone so there are no air extraction requirements. The fact that LEDs are mercury-free guarantees compliance with legislation on mercury and ensures safer operating environments. In addition, the low heat profile of GEW LEDs means fire risk and costly shielding and preparation of print units can be avoided.

    Reduced energy consumption

    Higher electrical efficiency of LEDs and the purity of UV output allow typical energy savings in excess of 50% on a typical UV arc lamp. Instant on-off switching means with LED no energy is consumed when the printing press is idle between jobs.

  • GEW LW2 LED UV curing system

    LW2 LED UV curing system for sheet-fed offset presses

    GEW’s patented LW2 lamphead is the most effective water-cooled LED UV curing technology on the market.

    Widest choice of substrates: UV LED polymer inks allow successful printing on almost all stock types. Coated and uncoated papers, plastics, foil laminated sheets etc. all become a possibility, increasing product diversity.

    No heat: Unlike H-UV or traditional mercury lamps, LEDs (light emitting diodes) emit very little infrared heat towards the substrate. This avoids common heat-related issues in sheet-fed printing such as high pile temperatures, curling of heat sensitive stock materials and loss of moisture in paper: printed sheets are crisp and fresh as new.

    Increased uptime: Instant on/off switching means that with GEW LED there are no warm-up or cool-down cycles that are required on conventional UV systems. Machine up-time is increased because the printer is never waiting for the lamps. In addition, because GEW’s LW2 has no moving parts there is no downtime to replace shutters, reflectors, mechanisms or lamps and maintenance costs are significantly reduced. Expected lifetimes of 20,000 hours guarantee trouble-free printing for years to come.

    Improved processes: UV LED inks and varnishes are 100% dry straight after the LED lamp. This eliminates messy and costly powder coating completely. More importantly sheets can be folded, cut and bound immediately after printing. This potentially allows stock reductions and significantly decreases lead-times to end-customers.

    Enhanced quality: UV inks can achieve sharper dots, higher gloss and better resistance to marking and scratching because the ink dries to a gloss polymer which is resistant to solvents and abrasion. GEW’s LW2 ensures perfect drying of UV LED inks every time thus eliminating marking and scratching issues observed in the perfecting or delivery mechanisms.

    Safer, future-proof printing: GEW LEDs produce no ozone so there are no air extraction requirements. The fact that LEDs are mercury-free guarantees compliance with any conceivable legislation on mercury and ensures operating environments safer than ever before. In addition, the low heat profile of GEW LEDs means fire risk and costly shielding and preparation of print units can be avoided

  • GEW NUVA2 UV Curing System

    Fully air-cooled UV curing system

    The NUVA2 UV curing system is the most effective UV technology for colour UV inkjet printing, as well as for high-speed coding, marking and serialisation.  NUVA2 are fully air-cooled UV curing systems. They are available in widths of up to 250cm (100in).

    With NUVA2 UV curing, your machine runs faster for longer, with less energy and no downtime.

    E2C systems are available with inert atmosphere curing. They can easily be upgraded to LED curing by using the same RHINO ArcLED electronic power supply.

    Where alternative products exploit conventional curing technologies that often neglect energy monitoring, GEW state of the art UV systems implement advanced UV lamphead technology associated with the most energy efficient power supplies.
