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 dark environment, products printed with fluorescent ink can produce a vibrant colored light. Compared to other oil-based or rubber-based ink particles, fluorescent ink particles are finer and softer, which gives it a unique transfer method during the printing process.

When selecting printing plates for fluorescent ink, metal plates should be used. Additionally, in order to ensure the luminous effect of fluorescent ink, paper with light or colored shades should be avoided, and instead, brighter and whiter paper should be chosen. This will make the luminescent properties more noticeable. When using coating printing, a small amount of ink should be used for the first printing and a second printing should be done. If printing on black or colored objects, an opaque ink should be used as a base layer before applying fluorescent ink.
