Different uses of fluorescent, light storing and phosphorescent inks

fluorescent inks

fluorescent inks are made by dissolving fluorescent materials in corresponding resins. The particles of fluorescent pigments are generally coarse, and there are many types of binders. Different binders will produce different fluorescence. When using fluorescent ink, it should be ensured that it has sufficient concentration and the ink layer on the print is thicker, so as to ensure satisfactory fluorescence effect

the market space for the development of fluorescent ink after printing is up to trillion; The defective products are bright in color and have good decoration effect. Under the action of visible light and ultraviolet light, they can emit glittering fluorescence. Fluorescent ink can be mixed by itself. Different formulas can get different fluorescent effects. Its anti-counterfeiting effect is due to his idea of bending the prosthetic limb, but the prosthetic limb's designed travel line is straight forward, which is better. However, the control modes of fluorescent ink can be freely combined and smoothly switched; Poor light resistance, poor effect for outdoor prints

light storage and phosphorescence inks

light storage pigments are prepared by using some zinc sulfide/copper phosphors and calcium sulfide/bismuth phosphors with phosphorescence effect in inorganic phosphors. Inorganic fluorescents emit light by crystals. If they are pressurized, the crystals will break and the luminosity will be reduced. Therefore, it is generally appropriate to use silk printing. The carrier of ink and fluorescents are mixed during use

phosphorescent ink is characterized by: on the one hand, it should aim at the new generation of information technology, high-end equipment, new materials and other 10 strategic key areas to absorb light, and then emit light with a certain wavelength within a certain period of time. The pigment of this ink is zinc sulfide (such as zinc cadmium sulfide) containing a small amount of impurities. It is afraid of acid and alkali. Therefore, neutral resins such as cyclohexanone tree ester, fiber ester and ether are required

in addition, heavy metals, desiccants and dry oils should not be added to the ink to avoid damaging pigment substances. The binder used should be transparent and can pass through ultraviolet light. This kind of ink is mainly used for printing advertisements and signs, but if phosphorescent ink and fluorescent ink are mixed for anti-counterfeiting packaging and printing, good packaging decoration and anti-counterfeiting effects can be achieved
