Introduction to anti-forgery ink

2024 09/30

 Anti-forgery ink can be divided into embossed, gravure, screen printing, offset printing, and water-based flexographic ink according to printing forms. Anti-forgery ink can be divided into paper ink, printing iron ink, news paper ink, plastic ink, etc. according to different substrates. Magnetic anti-forgery ink uses magnetic substances as pigments, such as iron oxide and cobalt doped iron oxide. The characteristics of these anti-forgery inks are achieved by implementing different external conditions, mainly using forms such as light, heat, and spectral detection, to observe the color changes of ink samples and achieve anti-forgery purposes. Color changing anti-forgery ink when in contact with water.
