Anti-counterfeit particle(also called anti-forgery particle, anti-clone particle, authentication particle, tracing and tracking particle, anti-theft particle, traceability particle, security particle)：The particle's diameter is between 30 micrometers and 200 micrometers. It shares many anti-counterfeiting features, including its natural color, way of changing color (such as from colored to colorless, from colorless to colored, from dark to light, etc.), combination modes of color (such as single color particle, bicolor particle, different colors between the front and the back, different colors between Marginal and internal, etc.), excitation condition (such as the sun light, ultraviolet light, temperature, observing angle, etc.), shape (such as round, triangle, square, letter, etc.) We can add all of the features to a particle by the order in order to increase the difficulty of counterfeiting.

The paper is usually used to make the packaging of pr oducts. Sometimes the paper of the packaging need to be added some anti-counterfeit features. To mix the security particles in the paper pulp is a effective method of making the anti-counterfeit paper, another method is to distribute the particles on the surface of the paper which is covered by the glue. It is very difficult to counterfeit the packaging which is made by the paper with security particles.

Several kinds of common anti-counterfeiting particle:

（1）Colored particle: The colored (such as red, green, blue) particles are usually used to be mixed in the paper pulp to make the security paper. They can be found under the natural light when they are distributed in the paper. The particles can be extracted from the paper by using the needle.


（2）Invisible UV excitation particle (also called colorless UV fluorescent particle): The particles are usually used to be mixed in the paper pulp to make the security paper. They are colorless (means white) under the natural light so that they are invisible in the white paper under the natural light, while they can fluoresce (such as red, green, blue) under the ultraviolet light. The particles can be extracted from the paper by using the needle.


（3）Visible UV excitation particle (also called colored UV fluorescent particle): The particles are usually used to be mixed in the paper pulp to make the security paper. They can be found under the natural light when they are distributed in the paper, while they can fluoresce(such as red, green, blue) under the ultraviolet light. The particles can be extracted from the paper by using the needle.

（4）Double-wavelength UV excitation particle: The particles are usually used to be mixed in the paper pulp to make the security paper. They are colorless (means white) under the natural light so that they are invisible in the white paper under the natural light, while they can fluoresce(such as red) under the long-wave ultraviolet light and fluoresce(another color such as green) under the short-wave ultraviolet light. The particles can be extracted from the paper by using the needle.

（5）Multi-color particle: The particles are usually used to be mixed in the paper pulp to make the security paper. There are more than one color (or UV excitation color) on a single particle. The colors and the rank of them constitute a specific character of the particle which is designed by the customer’s order. Some counterfeiters print many short lines on the paper to counterfeit the single color particle, but it is easy to differentiate the multi-color security particle in the paper and the short line printed on the paper by means of the following methods: a. To tear the paper or to extract the particle from the paper by using the needle, there are two(or more) colors on a particle. b. To observe the junction of the two adjacent colors in the short line(or on the particle) on the paper, there is no malposition or breakpoint on the particle, but the printed short lines are different, because the print technology level is not enough to make so high accuracy prints.
