River Falls, WI-based Air Motion Systems announces a breakthrough LED-UV based printing system for offset printing and perfecting using a cost-effective UV LED light source to instantly dry inks and varnishes at top press speeds without marking, without powder and without heat or wasted energy.

By instantly ‘trapping’ or drying both the front and back-side sheets inline, the LED-UV printing process reportedly eliminates marking concerns and dramatically speeds jobs through postpress.

Installed on 40-inch sheetfed offset perfecting press in Japan, the system represents the first production system of its kind anywhere in the world. Benefits include instant post-press processing, elimination of spray powder, removal of heat, and dramatic energy savings vs. infrared and conventional UV drying technology. The LED-UV system can be installed immediately following print units or over a special drying cylinder on the press, depending on machine configuration.

The new LED-UV system called "XP3" from AMS is based on patent-pending PEAK LED-UV curing technology first introduced by AMS one year ago to an international audience at PRINT 09 in Chicago. Using a new generation of ultra high-output UV LED chips in a compact, modular design, the system can scale to any width requirement and is effective at high-speed curing from distances up to 100mm (4 inches) away from the target media.

The AMS XP3 LED-UV system operates at as little as 20% of the electrical energy required of conventional UV systems, and without the heat, ozone ducting, human safety or lamp replacement and disposal concerns of conventional mercury lamps.

According to AMS President Steve Metcalf, "The XP3 LED-UV printing system represents breakthrough technology for printers looking to tap into the benefits of UV printing without the issues commonly associated with conventional lamp technology. For the first time, high-powered UV curing at real working distances is available from a 100% solid-state, semiconductor-based light source and is easily adaptable to a wide variety of new and existing machines on the market."

In addition to offset printing, the modular AMS XP3 LED-UV system architecture was designed to support digital, flexographic and a variety of other industrial curing applications where higher speeds and greater working distances are required. The XP3 system, which creates an intense emission of UV light to achieve the highest-possible index of curing efficiency, is available in single or multi-lamp configurations in a compact housing that simplifies installation, maintenance and process location. The system is available in widths ranging from 80mm (3 inches) up to 2m (80 inches).
