1. UV Light and UV Curing Why Cure with UV? Electromagnetic Spectrum and the Wavelengths DYMAX Utilizes Advantages of Curing with UV AND Visible Light Wavelengths, Intensity, and Energy Shortwave, Longwave, and Visible Light Four Types of UV Curing Systems The UV Curing Process • Mosaic Array UV LED chipset with surface emitting area of 12 mm2, 4:3 aspect ratio • All the benefits of chip on board processing without the need for complicated assembly process • Vertical chip UV LED technology for high power density and uniform emission • Wide Range of UVA Wavelengths
However, UV curing inks are as much as three times the cost of regular heatset inks, and are used only in specialty printing, such as liquor cartons, cosmetic packaging, metal decoration, screen printing, and flexography. The most common configuration of UV curing equipment is a mercury vapor lamp. UV LED Curing Because of the limited spectral wavelength, UV LED primarily operates in the UV-A zone and considered to be ‘safe’ because it is closest to visible light. However, prolonged exposure to this energy can be dangerous. The UV-B and much of the UV-C spectrums of light are primarily used for germicidal and sterilization purposes.
