Typical of many new technologies there needed to be a “starting‐point” where a specific benefit of the new technology “out‐ weighs” the traditional method. UV inkjet applications (particularly on heat‐ sensitive substrates) were an early and clear success for the UV LED curing lamps. Continued development has enabled the UV LED based curing lamp to be the best overall solution for UV inkjet curing applications.
UV LED curing has been adopted in all areas of printing, from digital inkjet to screen, to flexography and even offset. End users are increasingly asking equipment manufacturers for LED options, and the market‐leading vendors are responding. Confronted with such exciting and rapidly evolving technology, system builders and end users are closely monitoring the ever‐changing UV LED curing landscape. Today, UV LEDs have gained their place as a mainstream curing technology throughout a wide range of printing applications.
UV LED curing solutions are being utilized in the coating industry because they offer lower operating costs, enhanced system capabilities due to being a solid-state device, and environmental benefits of safer workplace environment and no hazardous materials. UV LED technology drastically reduces energy consumption and significantly reduces work-piece surface temperature. Machines can be made more compact due to small form factor; speed can be increased due to consistent UV output; and the diffuse nature of UV LED light can be used to more effectively cure shaped surfaces which previously required multiple lamps at various angles. UV curable coating applications include wood and vinyl, automotive, musical instruments, fixtures and many others.
Adhesive bonding, sealing, and coating processes in factory assembly lines are rapidly upgrading to UV LED curing technology. UV Adhesives
are a great tool in modern assembly and manufacturing processes with UV LED electronic control and stability ensuring excellent results in a wide variety of UV LED adhesive applications from medical devices to the most advanced consumer electronics.

Today, many electronics manufacturers use UV LED curing in the production of products such as touchscreens, mobile phones, micro-speakers, and hard disk drives.
A More Sustainable Future
The mercury ban in manufacturing processes is growing globally. All the major brands are requiring environmentally sustainable processes from printers, converters, and other manufacturers. Now that LED has become a valid alternative to mercury, many large global companies are eliminating mercury from all their factories. A UV Lamp typically contain up to 250mg of mercury and each lamp needs to be replaced every 1500-3000 hours. Mercury poisoning causes damage to the central nervous system, kidneys, and many other organs.
The environmental benefits of UV LED curing are numerous. Phoseon customers have experienced energy savings up to 85 percent with the implementation of UV LED curing systems. With traditional UV curing processes, the tremendous heat associated with mercury UV lamps required a lot of electricity to operate. Mercury lamps produce ozone, which is a greenhouse gas and is for the operator to inhale, especially in a constricted space like a print shop. Air exhaust systems are required to extract the toxic fumes from the presses. These exhaust systems can be eliminated with UV LED curing. LED is the only sustainable choice for UV curing.
