The colorants used in fluorescent ink are usually pigments or dyes. Unlike ordinary ink colorants, fluorescent ink can reflect visible light and absorb short-wavelength light such as violet, blue, and green, and then reflect visible fluorescence. The colored substance printed with fluorescent ink ca...
Under normal conditions, the lifespan of photochromic fluorescent anti-counterfeiting ink under sunlight is 30 days. With the development of printing and new material technologies, the indoor lifespan of photochromic fluorescent anti-counterfeiting ink has been greatly improved, and even can be used...
Anti-counterfeiting printing technology involves many fields such as spectrum technology, printing technology, packaging technology, optics, chemistry, physics, electromagnetics, computer technology, spectral technology, printing technology, and packaging technology. It is an interdisciplinary and c...
As more and more people use ink for printing or decoration, fluorescent ink, as a new product, is introduced here to highlight several precautions for blending. When blending fluorescent ink, it is necessary to match the ink color with the color design of the decoration, minimizing the difference an...
Photochromic ink, commonly known as color-changing ink or color-shifting ink, for example: red-green, gold-silver, etc. It has strong photochromic properties and significant color differences, making it difficult to replicate and highly counterfeit-proof. Many countries around the world use this typ...
Due to its special characteristics in the ink system, UV fluorescent ink has very strict requirements for printing processes, and the following issues need to be especially noted when using it: (1) Slow volatility: Advantages: Excellent reproducibility of printed images; Disadvantages: It cannot be ...
In the era of banknote payments, producing high-quality banknotes is difficult, and the most challenging part is anti-counterfeiting. Nowadays, the most advanced anti-counterfeiting technology is optically variable ink, which has strong color-changing properties, a significant color difference, and ...
I. Printing methods: Fluorescent ink is typically printed using one of four methods: screen printing, offset printing, transfer printing, or pad printing. It comes in four colors: red, yellow, blue, and green, and can be printed alone or in combination on common substrates such as paper, fabric, met...
Optically variable materials have a distinct color change effect and can be visually distinguished at different angles, making them easily recognizable. They possess specific spectral characteristics, such as a five-layer optical interference inorganic material and multi-layer optical interference i...
