While conventional UV curing through the use of microwave and arc lamps has been used in automotive and transportation production processes for decades, UV LED curing is relatively new and has not gained much traction. In other markets, however, UV LED technology is much more mainstream, as significant equipment and formulation advances enable the technology to quickly penetrate a growing range of applications. This is primarily driven by the fact that UV LED technology offers numerous performance, operating and environmental benefits and is considered an enabling technology that lends its use to curing inks, adhesives and coatings on a greater range of heat-sensitive materials while delivering overall process and quality control. As a result, the transformational nature of UV LED curing is something that should be explored and evaluated for its production use viability as automotive and transportation companies strive to meet various manufacturing challenges over the coming decade.
UV LED curing refers to a technique that uses energy output from the light emitting diodes (LED) in the ultraviolet (UV) spectrum to treat inks, coatings, adhesives and other UV curable materials.
LED lamps provide many advantages including lower energy consumption, longer lifetime, improved robustness, smaller form factor, and faster on/off switching.

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 60,000 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.

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.
