Technology Bi-fluorescent inks Protection strategy Product authentication Type Overt feature System Security inks Medium Secondary packaging Authentication/Identificaton Authentication Traceability No Cost Price on request Required equipment Irradiation with an integrated, dual-wavelength lamp or two separate lamps Vertification level Pharmacist (with the adequate light excitation sources) N.B. Description Fluorescence is the emission of light by matter after irradiation with light of a different wavelength. The fluorescent inks normally used for security purposes glow visibly under ultraviolet light. The effect is immediately reversible, and fluorescence ends when the excitation light is removed. Bi-fluorescent inks is the combination of two pigments that different wavelengths of incident light (the two wavelengths can still be in the same spectral region e.g. UV). Strengths Low cost; Can deter simple attempts at counterfeiting (such as color photocopying); More secure than single-wavelength fluorescence; Limitations Not considered high security option; Easily reproduced; Require irradiation with two specific wavelength; Links:
