The UV curing process uses UV energy and light from the visible light spectrum in wavelengths from 200 to 480 nm. UV energy "cures" inks and varnishes in a fraction of a second. A UV system consists essentially of the following components: UV lamps, reflectors, lamp housings, a cooling system and an electronic operating and control system. 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
UV LED Curing Lamp is widely used in printing ink curing, glue curing, painting curing, resin curing and other fields. It contains lots of wavelength, such as 365nm, 385nm, 395nm, etc.. It can be fixed and removable, easy to operate. And we also can provide solutions for customers. 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. Usually UV-A is used to cure UV adhesives, UV inks, or UV coating. The most common UV-A wavelength for curing UV materials is LW370 (peaks at about 368 nm), however, for some adhesives LW350 (peaks at about 352 nm) will work just as well. The exact UV wavelength might need to be determined to see which UV lamp (bulb) should be used. UV Technology Ultraviolet reactive inks and coatings require a high intensity source of ultraviolet light to initiate a chemical reaction, curing the ink or the coating almost instantaneously. Ultraviolet light forms a small part of the electromagnetic spectrum which ranges from radio waves at the long-wave end, to x-rays and gamma rays at the ...
Most plastic bonding UV adhesives have a longer wavelength photoinitiator which reacts with 400-420nm wavelength and will react in normal daylight fairly well. Glass bonding products have a photoinitiator which is activated when exposed to UV light of 365-400nm wavelength. In composite initiator system, for magenta UV curable jet ink, blue UV curable jet ink and yellow UV curable jet ink, the curing time of Irgacure369/ITX was less than other photoinitiators. For black UV curable jet ink, curing time of Irgacure184/ Irgacure819 was less than others. References  Li Lu-hai, Zhang Shu-fen, Yang Jin-zong, Zou Jing.
The types of UV lamps used for UV ink curing includes low pressure and medium pressure UV (MPUV) curing lamps as well as amalgam UV curing lamps. Using a wavelength of 254nm, UV low pressure lamps are used to cure inks in high-quality magazines and newspapers. For the longer-wavelength UV devices, in a similar manner to blue LED fabrication, InGaN-based epilayers are grown on sap-phire substrates to produce 385, 395 and 405 nm UV LEDs for curing. One key advan - tage to higher-wavelength devices is that they can be driven at higher power. “395 nm is really the sweet spot for UV LED curing, All coatings, whether paints, inks or adhesives, require a perfect,dry and cured surface. Depending on the process and the coating for curing, infrared heat, UV light or a combination of both technologies, like "Hybrid Cure ", are efficient solutions.

Download the Products Overview Brochure for more information Most plastic bonding UV adhesives have a longer wavelength photoinitiator which reacts with 400-420nm wavelength and will react in normal daylight fairly well. Glass bonding products have a photoinitiator which is activated when exposed to UV light of 365-400nm wavelength. Which applications get the best results with LED UV? Double production speed can be achieved with thick, heavily pigmented inks. The LEDs’ high intensity UV-A rays penetrate thick ink coats better for more consistent curing with improved adhesion, delivering faster speeds with silkscreen, laminating and flexo base white.
Ink used for Acuity LED 1600 is UV curable ink (UV ink), which is excellent in drying property and processed quickly. Inks used for wide-format printing are roughly divided into two types: Solvent ink containing a volatile solvent is dried by heating and UV ink containing a reactive monomer is polymerized and hardened by UV light. To polymerize ... The inks provide excellent inter-coat adhesion between paper – ink – melamine – resin, without any tendency to bleed thanks to UV curing. Cleaner and ink meet the IKEA standards listed in IOS-MAT-0010 and IOS-MAT-0066. The basic colors of the digital printer can be set (pinned) with a UV-LED (395 nm) and then fully cured by exposure to ...

Darocur® 4265 Excellent for curing white inks and coatings. For additional information about individual products or specific applications, please contact your local Technical Representative. Ciba Photoinitiators for UV Curing 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. All inks and coatings each have their own characteristic spectral absorbance, ranging from high absorbance of short UV wavelengths, to lower absorbance for longer wavelengths.(5) Spectral absorptivity is a key factor in determining the best wavelengths for most effective curing. A Simple Method to Determine Spectral Absorption The Phoseon FireFly is an air-cooled small form factor UV LED curing lamp with peak intensities up to 8W/cm². The FireFly product is ideal for small area and spot cure applications. It perfectly suits the UV curing of adhesives, inks, electronic materials and biomedical materials. The addition of gallium to the lamp yields a strong output in the longwave range between 400 and 450 nm. This makes the V lamp a good choice for curing white pigmented inks and base coats containing titanium dioxide which blocks the most shortwave UV. Fluorescent lamps. Fluorescent lamps are used for UV curing in a number of applications.
