Teach you to know the Diary Glitter Notebook colorless ink in printing

Now all kinds of new anti-counterfeiting technology emerge in endlessly, anti-counterfeiting technology, the key is to extend the timeliness and uniqueness of anti-counterfeiting technology, is also the main purpose of anti-counterfeiting technology. And now anti-counterfeiting technology mainly includes: Diary Glitter Notebook printing design anti-counterfeiting, printing paper anti-counterfeiting, printing ink anti-counterfeiting and printing process anti-counterfeiting. Among them, printing ink anti-counterfeiting technology has a good development situation and an increasingly wide range of applications.

1, Diary Glitter Notebook fade ink security principle

The so-called security ink is added in the ink binder special performance security material, special printing ink processed by special technology. Security ink according to its security function is mainly divided into the following:

① Magnetic anti-counterfeit ink

(2) fluorescent ink and phosphorescent ink

(3) reactive color changing ink

(4) anti-modification ink

⑤ daylight inspired color changing ink

⑥ Intelligent anti-counterfeiting ink

⑦ infrared ink

⑧ Nano ink

The reaction color changing ink is an important part of the anti-counterfeit ink, and can be divided into: thermal color changing ink, photosensitive color changing ink, wet color changing ink, pressure sensitive color changing ink. Reaction color ink is to add a variety of chemicals in the ink, under certain conditions (such as light, heat, humidity, pressure, etc.), can occur a variety of chemical reactions, so that the ink change color, to achieve the purpose of anti-counterfeiting.

2, Diary Glitter Notebook colorless ink classification

(1) water bleaching ink

Water colorless ink is also known as wet sensitive ink, anti-counterfeit principle is the color material containing with the change of humidity and color change, water or bleach can make colorless, generally contains oxidant or reducing agent dissolved in water material. The security feature is colorless dry state and colored wet state. Water colorless ink is divided into reversible colorless, irreversible colorless, wet-sensitive diffusion three, with blue, green, black, red four colors.

● reversible bleaching ink: after dripping color from color to colorless, volatilized after the recovery of primary color, color from white to no, only screen printing, gravure printing. For example, it is recommended to use 200 mesh screen printing, the thicker the better.

● irreversible bleaching ink: oily ink, dripping from color to colorless, water droplets volatilized, the color is no longer restored to the original color, color black → no, red → no, blue → no, green → no. Only screen printing, gravure printing, printing requirements thin, bright color, fade effect is good, such as screen printing recommended with 350-420 mesh screen printing.

● Moisture sensitive diffusion is irreversible, the color is red, yellow, blue, green, etc., can only use water screen printing.

(2) organic solvent bleaching ink

Such as alcohol, gasoline, benzene and so on. The principle of organic solvent discoloration and water discoloration is basically the same, according to the reaction of the corresponding chemical substances to make them fade.

(3) compound colorless ink

The synthesis of water and organic solvent colorless ink, we can call it composite colorless ink. Compound colorless ink can react to aqueous solvents, bleaching and organic solvents to achieve the purpose of colorless. Compound colorless ink is the trend of the development of security ink, compound security ink can not only prolong the service life of security ink, but also improve the security effect.

(4) binary security ink

Binary security ink, refers to the bleaching ink contains fluorescent components, under the irradiation of ultraviolet light, can easily distinguish whether used solvents. Part of the fading ink contains visible fading components, and has a permanent fluorescent component. Under visible light, it doesn't seem to exist, but under ultraviolet light, it can be seen by the human eye.
