Understanding Ultraviolet LED Wavelength

UV LED Curing Wavelength Spectrum
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.

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. Read more »
