GEW ArcLED hybrid UV curing system

Nilpeter is first press manufacturer to install GEW’s ArcLED UV

CINCINNATI, OH—Nilpeter is the first press manufacturer to install GEW’s new ArcLED hybrid UV curing system. It will be installed on three FA-4* UV flexo presses, which are designed for high productivity of pressure sensitive labels and flexible packaging.

Two of the FA-4* orders come from large, long established American converters. The first ever ArcLED hybrid press was acquired by Flexible Technologies based in Orem, UT, a privately owned company. The second American company is Best Label Co., a privately owned company formed in 1976 and headquartered in Cerritos, CA. A third press FA-4* with the hybrid curing system has been delivered to U.K. based OPM Group.

For Digital Inkjet Printing, Too

The ArcLED UV curing system is also an option for Nilpeter’s new PANORAMA UV Inkjet digital press line. It receives its global debut at Labelexpo Europe in Brussels in Hall 7, Stand No. 7B35. This major development from the Danish press manufacturer integrates many of the company’s inline converting options adapted for full color digital printing. The PANORAMA DP-3 prints CMYK and opaque White at up to 164 fpm to a maximum print width of 12.67-in.

How The System Works

GEW’s hybrid ArcLED UV system uses uniform lamp head casings with interchangeable cassettes. As a complementary process, it allows press operators to run with LED and mercury arc curing units freely positioned on the press to suit specific printing and varnishing applications. Changeovers of individual cassettes take just a few minutes. GEW’s compact Rhino power supply automatically recognises individual cassettes and switches seamlessly between DC power for the LEDs or high voltage AC for mercury arc UV curing. This approach also offers converters an economical upgrade path for partial or full LED curing, as well as providing a future proofed technology.

Lower energy costs, helped by the most efficient mercury arc lamp units and power control systems, is a major benefit. Further energy savings are possible with LEDs, which are either “on” or “off”: No energy is consumed while the press stands idle between jobs. ArcLED lamp heads are available in widths up to 36.5-in. Typical wavelengths are: 405-nm., 395-nm., and 385-nm. in power levels up to 22 w./sq. cm.

The ready availability of dedicated ink and varnishes, including opaque white inks, has seen LED technology spread from industrial inkjet applications, such as Nilpeter’s PANORAMA DP-3, to a growing acceptance among UV flexo converters. Different ink formulations also allow its usage for screen process and rotary offset printing.

At Labelexpo Europe, Nilpeter will demonstrate an FA-4* press as part of the PackPrint Workshop in Hall 8. Its innovative sleeve system permits an extra short web path with easy loading of tooling. It will be producing high quality flexible packaging and labels in short runs with various repeat lengths at the show.
