An increasing number of printers are opting for LED curing technology regardless of the printing process used. LED curing technology opens the door to new revenue opportunities with more press uptime, less maintenance and the ability to print on films and other heat-sensitive substrates, offering increased profitability for printers and converters. The return on investment can be quite fast due to the operating savings and benefits.
UV wavelengths typically are measured in nanometers (nm). Nanometer, a unit of length, is equal to one billionth of a meter. UV light-emitting diodes (LEDs) have a narrow spectral output centered on a specific wavelength, +/- 15nm, with typical commercial UV LED lamps emitting at 365nm, 385nm, 395nm, or 405nm wavelengths.

UV LED technology delivers hassle free curing on new and existing narrow web presses. The system efficiently cures inks and coatings printed on a variety of substrates, including thinner filmic materials, which can be sensitive to the higher temperatures generated by traditional mercury offerings. UV LED generates far less heat, providing greater flexibility in material selection and a consistent cure at higher speeds.
An increasing number of printers are opting for LED technology, regardless
of the printing process used. With LED's potential for eco-efficiency, cost effectiveness and productivity advantages, it is one of the most compelling technological advances in recent years and will drive future development in the printing industry.
Ultraviolet (UV) curing is a photopolymerization process that uses energy to change a liquid to a solid. Upon absorption of the UV energy, the photoinitiators produce
free radicals which initiate cross linking with binders (monomers and oligomers) in a polymerization reaction to cure or solidify the ink,coating or adhesive.
LED curing solutions are utilized in the coatings industry because they offer highly reliable UV curing due to being a solid-state device. They provide deep through-cure and allow low surface temperatures that enable less expensive raw inputs.
This article from Narrow WebTech takes a closer look at the pros and cons of conventional UV and UV-LED curing technologies. With over 225 patents and trademarks and more than 45,000 units shipped, Phoseon believes the UV LED curing market is gaining foothold! Phoseon products tested in our lab have surpassed 50,000 hours of on-time with minimal degradation in UV output. UV LED technology has gone mainstream in digital printing, is gaining significant adoption in screen printing, and the next to take off will be flexo.
Just a few years ago, UV LED curing technology was not a viable solution for most package printers and converters. Though the technology was purported to offer several benefits, including increased uptime, the ability to cure dense colors and substantial energy savings, LED compatible ink had not yet broken onto the scene.
Now that LED ink availability is of minimal concern, more converters are looking into adding this breakthrough curing method. But before switching out traditional UV arc lamps for LED, converters should be aware of exactly what to expect when making the change, and whether LED is right for them.
LED curing technology has arrived. It is no longer an emerging technology, but an enabling technology− one that is bringing a host of advanced capabilities to printing.UV LED light sources are ideal for high-speed curing in narrow-web presses and other forms of printing such as screen, digital and offset, offering many benefits to printers and converters that make it an appealing option for any size operation.

The conference opened with Jennifer Heathcote of Phoseon Technology, who discussed “Technology Trends Driving the Adoption of UV LED Curing.” Heathcote gave a general presentation on UV LED curing equipment. “LEDs are going to increase in output,” Heathcote noted. “Laboratory LED work is being done at much higher levels.”
AN order for a six-colour EF340 MPS multisubstrate flexo press, featuring Phoseon’s UV LED drying, marks the first press in South Africa to use this type of curing. The partnership resulted from the need to meet growing demand for lower running costs and energy costs. Phoseon’s UV LED technology offers significant energy savings (above 50% the company claims) and its instant on/off capability helps to deal with South Africa’s power outages and fluctuations.
Partnering with Phoseon and their LED curing technology makes GM Graphix a pioneer in the South African market. Their partnership resulted from the need for a solution to accommodate the growing demand in South Africa for lower cost and security of energy supply, to integrate with GM Graphix’s next press acquisition from MPS. The choice for LED technology from Phoseon was made because of the significant energy savings at +50% and instant on/off capability to deal with power outages and fluctuations.
Now that UV LED curing has gained worldwide acceptance, converters are recognizing the increased capabilities and the real-world benefits as it opens the door to a wider variety of substrates and new applications.
UV LED curing is ideal for a variety of packaging applications, enabling end users to print on a variety of packaging materials at high speeds.

Technological advances in LED development have been achieved in the past 10 years as Phoseon Technology discusses.
First let’s get the acronyms sorted! UV is simple – most will know that it’s short for ultraviolet. But LED (light-emitting diodes) may be less well-known. Marrying the two, UV LED curing is a fast-emerging technology used to treat surfaces with monochromatic UV radiation from LEDs.
Curing with UV LED is an emerging technology that is slowly gaining momentum in the flexographic print industry.

Ink Mill Corporation is a high quality ink manufacturer for Ink Jet applications including UV LED inks.
Users of UV LED curing can expand their application range, achieve better quality and use less energy by working with chemistry companies and equipment developers.
It is very important to point out that low migration is not about an ink, but about a process. The process includes the following: press, substrates, ink, curing, rollers/screens (in case of flexography/screen respectively), ink film thickness, color print order and max ink deposition.
The wide-format printing sector is familiar by now with ultraviolet (UV) curing, which has allowed compatible inks to be instantly polymerized during the printing process, rather than rely on more traditional solvent-based inks, which must be allowed to dry and off-gas after printing.
