UV LED Technology Improves Flexography Printing

Phoseon Technology is revolutionizing the narrow-web printing industry by combining flexography, which has been used for printing for more than a century, and UV-LED curing technology, which Phoseon first introduced to the narrow-web industry in 2009.

Phoseon’s technology uses UV LED light to rapidly set, or “cure,” ink used in printing, resulting in a higher quality product without the use of solvent-based inks.

Flexography utilizes a flexible relief plate — a modern version of letterpress — to print on nearly any type of material, from paper to plastic to metallic film. Unlike solvent or water based flexographic inks, UV inks dry almost instantly when exposed to UV light, resulting in a sharp and colorful image. With a UV-LED solution, Phoseon is enabling converters to enjoy the benefits of UV curing without the typical costs and hazards of operating an arc lamp to produce the UV light.

“UV LED allows you to complete a wider range of print jobs with higher quality, faster and more consistently,” said Jennifer Heathcote, regional sales manager at Phoseon Technology.

Narrow-web printing — a term primarily pertaining to a printing width under 30 inches — is often used for printing labels, plastic bags and flexible packaging. In addition to higher quality, UV LED curing for flexographic printing allows for better process control, less waste and the ability to run presses faster than with traditional narrow-web printing methods.

The FirePower FP601 is a water-cooled solution with advanced control features using a Modbus interface and a high intensity output for the fastest possible cure speeds. The FireJet™ FJ601 simplifies retrofits with a self-contained air-cooled design that eliminates the need for air-extraction systems or water-cooling systems.

In addition to narrow-web printing, Phoseon Technology’s UV LED technology also is used in a wide range of other applications, such as wide-web and decorative printing, manufacturing wood, and curing wood and filament coatings.
