A Case for UV LED Curing (English)

UV LED curing technology is no longer an emerging technology, but is being seen more and more applied to screen printing, flexographic, and digital printing. Sara Jennings from Phoseon describes the technology and the companies using it.

Today, UV LED lamps are improving the print quality, throughput speeds, and capabilities of devices used to print everything from bottles, labels, and backlit signs to Braille lettering.

Owners of printing equipment that use UV LED curing lamps are reaping measureable and marketable benefits including:

  • the ability to print on many thin or heat-sensitive substrates
  • substantial energy savings compared to arc-lamp curing
  • improved print quality, particularly with multi-colour imaging and fine text
  • higher levels of workplace safety
  • increased productivity with longer-lasting, lower-maintenance ink-curing systems

Designers of specialized printing equipment are choosing UV LED curing lamps because they deliver advanced capabilities, improvements in operating economics, and environmental advantages.

Developers of printing equipment are choosing UV LED curing technology because of the following advantages:  the curing heads are small enough to be used in smaller, more compact machines. Without generating a lot of heat or consuming high levels of electrical power, UV LED curing units can produce deep, thorough curing on a huge range of substrates. UV LED lamps can provide controlled curing intensity on thin plastics, foils, and films that would soften, warp, or discolor under the heat produced by UV arc lamps.

Because a UV LED curing lamp is a solid-state electronic device, it can deliver more than 20,000 hours of operating life. Consequently, printing equipment owners don’t have to spend the time or money to change out the curing heads as often as arc lamps that have an average operating life of about 2,000 hours.

Designers of specialized printing equipment are choosing UV LED curing lamps because they deliver advanced capabilities, improvements in operating economics, and environmental advantages. Over the past few years, a growing number of ink companies have been working hand-in-hand with printing equipment developers to develop ink formulations that that are optimized for both UV LED curing and the specific application.

Users of UV LED curing and ink technology can expand the range of applications they can offer, run equipment at higher speeds, achieve new levels of print quality, use substantially less energy, reduce scrap, reduce VOC emissions in the workplace, and print on lower cost or more environmentally friendly materials.
