UV Offset Security Inks
Nanografi UV security inks are special inks that become visible under ultraviolet (UV) light. They can be invisible under normal light, but fluoresce in certain colors under UV light. They are generally used in banknotes, passports, ID cards, branded product labels and other printed materials that require security for the purpose of preventing counterfeiting.
Features:
They glow in certain colors under UV light.
They are usually pale when seen with the naked eye.
They have formulations that are sensitive to different wavelengths (types that are activated under 365 nm or 254 nm UV light).
They can exhibit photoluminescent properties.
They reduce the risk of counterfeiting because they are difficult to imitate.
Areas of Use:
Banknotes and stocks
Passports and ID cards
Brand protection and combating counterfeit products
Certificates and tickets
Legal and security documents

365 nm Ink (Long Wavelength)
Nanografi UV security 365 nm ink fluoresces under UV light at a wavelength of 365 nanometers. Long wavelength inks are often used in security documents and identity verification processes because UV light at this wavelength is more common and easily accessible.
254 nm Ink (Short Wavelength)
Nanografi UV security 254 nm ink, which responds to UV light at a wavelength of 254 nanometers, requires a more specialized UV light source. Short wavelength inks are preferred for higher levels of security because light sources at this wavelength are less common and therefore more effective in preventing counterfeiting.
Bı-fluorescent Ink
Bi-fluorescent inks are designed to fluoresce at two different wavelengths (365 nm/254 nm). This provides an extra layer of security on the document or product because the ink glows in different colors under two different UV lights.
Trı-fluorescent Ink
Able to fluoresce at three different UV wavelengths, this ink is suitable for more complex security requirements. The ability to fluoresce in three different colors (colors?) provides a significant advantage against counterfeiting.
Quatro-fluorescent Ink
One of the most complex security inks, capable of fluorescent at four different UV wavelengths. This ink is ideal for applications with very high security requirements and offers maximum protection against counterfeiting.
