What is the curing wavelength of UV ink? Is the wavelength of 365nm or 395nm better for UV ink curing? The LED curing lamp 365/395 for led uv ink refers to the wavelength (unit is nm). Generally, the shorter the wavelength, the better the penetration.
What is the curing wavelength of UV ink? Is the wavelength of 365nm or 395nm better for UV ink curing?
1, 365nm purple light (generally refers to the wavelength 360-365NM)
365nm wavelength ultraviolet LED is more expensive (for violet ultraviolet rays, the shorter the wavelength, the more expensive)
365nm: The light that can be seen, but the light is very weak. With 365 quasi-wavelength ultraviolet lamp beads, the luminous color can hardly see purple light, because the imported chip’s luminous color does not contain purple light, and almost all kinds of authenticity are identified. Products can use it, fine inspection of jewelry, jade, jade, amber, invoices, stamps and other items, flaw detection (industrial use, parts precision scar identification), fluid trace detection (oil stains, criminal investigation detection, etc.), because it does not carry purple light , Can accurately distinguish the subtle traces, fluorescent agent detection must choose to use it, most UV glue must also use 365nm, and some fluorescent photography, fluorescent art stage effects also need to use wavelengths below 365nm. .
Is the wavelength of 365nm or 395nm better for the UV ink for curing UV materials?
2, 380nm purple light (usually 380~385nm)
380nm ultraviolet light is basically suitable for all kinds of authenticity identification. Scope of application: foreign currency, jade, jade, invoice, etc., but with a little purple visible light, the effect is worse than that of 365NM!
Curing UV glue will be better than 395. In the case of fluorescent printing, 380nm is particularly cost-effective.
3, 395nm purple light (generally 395~405nm)
Scope of application: (UV ink curing, UV paint curing, UV ink, UV coating, glue curing; fishing lights, indoor mosquito repellent lights; fluorescent reflection of special substances (photographing scorpions, catching scorpions, currency checking, etc.); UV nail lamps, Violet jewelry lamp.
