The development and manufacturing of optically variable pigments have expanded beyond traditional optically variable pigments to include a range of new optical color-changing pigment products such as high chroma optically variable pigments, same color different spectra optically variable pigments, e...
UV fluorescent ink has strict requirements for printing technology due to its unique characteristics in the ink system. The following points need to be paid special attention to during use: (1) Slow volatility: Advantages: good reproduction of printing images; Disadvantages: unable to completely eva...
The luminescence principle of fluorescent ink is to store the light energy under illumination and convert it into internal energy, and then convert it into light energy through photochemical reaction and emit it. Generally speaking, the emitted light after absorbing light energy can be divided into ...
As we all know, there are many different types of optically variable ink depending on the manufacturing process. Here, we will take a few common examples of optically variable ink and introduce their operation and application. This is a widely used optically variable ink in fiber products due to its...
When using fluorescent ink for printing, patterns with large color differences may have a defect called white spots. In this case, it is necessary to perform defect handling. For example, when printing large areas, yellow fluorescent ink is used for patterns containing black text, and defect handlin...
When using fluorescent ink for printing, there may be a defect called "white gap" in the color effect of patterns with large color difference. In this case, hazard printing should be carried out. For example, when using yellow fluorescent ink for printing patterns containing black text on a large ar...
Fluorescent ink is a special pigment with unique luminescent properties. Here, we introduce its performance characteristics and printing techniques. Special color pigments in fluorescent ink can absorb energy from ultraviolet light and convert it into visible light of longer wavelengths. Thus, in a ...
UV fluorescent ink is a special type of ink that emits visible light between 400nm to 800nm when exposed to ultraviolet radiation between 200nm to 400nm. This ink is easy to print, cost-effective, has good concealment, bright colors, and convenient inspection, making it highly favored by consumers. ...
Optical variable ink is a typical anti-counterfeiting ink in the field of packaging printing. In recent years, it has become a common practice to apply anti-counterfeiting technology to packaging in order to protect consumers' rights and ensure the reputation of enterprises. Here we will introduce t...
