UV LED Curing Wavelength Spectrum

Understanding Ultraviolet LED Wavelength

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. more »

Movin' On: Upgrading Press Equipment & Debunking Myths

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. more »

Technical, Reliable & Beneficial: UV LED has Impressive Endurance, Brings Advantages to Package Printing

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 crosslinking with binders (monomers and oligomers) in a polymerization reaction to cure or solidify the ink, coating or adhesive. more »

LED Curing Technology for Advanced Printing

UV LED curing technology has arrived. It is no longer an emerging technology, but one that is bringing a host of advanced printing capabilities — UV LED light sources are suitable 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 making it an appealing option. Although there is an expense associated with upgrading to UV LED equipment, the return on investment can be quite fast due to the overall cost savings and operating benefits. Here, Phoseon Technology sets the record straight with some of the myths from the industry. more »

Best Practices: Flipping the Switch on LED

Just a few years ago, UV LED curing technology was not a viable solution for most package printers and converters. 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. more »
