The security features and identification method is the soul of security labels, security is to those for the purpose of fraud and without the permission of the owner of imitation or copy activities and take preventive measures.The significance of security labels is brand users to protect their own brand scheme and effective means, security labels in today’s more and more widely used, can be divided into the following categories:

• Holographic security labels                                                                                                                               

Also known as laser security labels, or hologram security labels.

• Printing security labels, printing security documents and bills.
• Double-card security label

There are four kinds of double-card anti-counterfeiting labels: moir stripe double-card, nuclear track double-card, polarization optical double-card and random encryption hidden text double-card.

• Graphic output laser security label;

The use of laser beam on the surface of the subject to form a graphic security mark.

• Nuclear microporous security labels

That is nuclear track anti-counterfeiting.Ionizing damage is caused by irradiation of organic thin film by heavy ion generator or nuclear reactor (national control equipment) imaging method.A formed track is etched with a strong base or acid to make it microporous.Composed of micropores graphics.Its security features are: in the visible light, due to micro-aperture diffraction and scattering, the visual effect observed by the human eye is white text and text.If dripping water on the water into the micro hole, the text disappeared.If smeared with colored liquid, colored liquid into the micro hole, wipe off the surface of colored liquid, rendering colored text and text.

• Graphic disclosure security labels

Graphic disclosure security labels are divided into the following:

(1)Yin and Yang text reveal anti-counterfeiting labels

The surface layer and the sub-layer have complementary Yin and Yang graphics.The adhesive applied on the graphic parts of Yin and Yang has different bonding strength.Before the revelation, Yin and Yang complement each other and become a whole, in a state of visual concealment.Only after the disclosure can they be separated from each other, the surface layer and the secondary layer have corresponding separate Yin and Yang text, can not be recovered after the disclosure.

(2)The entire coating to reveal anti-counterfeiting labels

When the layers are removed, the surface characteristics of the bottom layer (full coating) are different from that of the graphic parts of Yin and Yang.

(3)The rules reveal anti-counterfeiting labels

It is basically the same as the Yin and Yang graphic disclosure anti-counterfeiting mark, but it can also form the following characteristics: namely, the upper surface of the surface has printed graphics and graphics, the surface layer and the next layer have complementary graphics and graphics of Yin and Yang.The adhesive applied to the graphic parts of Yin and Yang has different bonding strength.Before revealing, Yin and Yang should complement each other as a whole and be in a state of visual concealment.Only after the exposure can they be separated from each other, the upper and lower surfaces of the surface have the same or complementary transmittance graphics corresponding to the position.

• Invisible text security labels

The security label is made of materials with regression reflection characteristics, including flashing Angle image type, multi-dimensional flashing Angle type, reflective watermark type, etc.

• Magnetic code security labels

The security label is printed using magnetic ink.For example, the magnetic ink made from magnetic powder is mixed with the information characteristics (such as code bar, code width, code distance) and the magnetic characteristics (residual magnetic ratio, coerce ratio) by printing methods such as PS adhesive mixing and screen printing.The hidden magnetic code discriminator was used for identification (rapid magnetic measurement by impact sensing, accurate testing of various characteristics of coded materials, and completion of logic decoding).

• Mark distribution security labels

The security label is made of three-dimensional color fiber distribution, which is called texture distribution security mark.The anti – counterfeiting label made of colored reflective particles and white raised microbubbles is called anti – counterfeiting label.This kind of original sign belongs to our country, the sign is authoritative and difficult to imitate is good.

• Overlay security labels

The security label with a cover layer covering the corresponding authority of digital or graphic information, that is, digital security, the label is divided into scraping type and open type two.The cover layer is removed, should not be used again, the most common is the digital scratch type and digital open security labels, the inquiry way has SMS security inquiry, 400 phone, 800 free phone, fixed phone, website inquiry, 315 security to provide a full set of services.

• Original light carved anti-counterfeiting labels

This anti-counterfeiting label USES the high resolution light engraving technology plate making, forming on the thin film grating spacing is less than or equal to 0.4 micron hologram, in the white light slanting zero order diffraction is the direction of reflection, forming the thin film isohedral interference graphics and text.China’s new id card USES the world’s top high-tech technology, rotating 90 degrees along its plane to change the color of the design of the Great Wall.

• Rfid tags

RFID is the abbreviation of Radio Frequency Identification, commonly known as electronic tags.Is now the most advanced form of a security label.For example, we usually use the access card, bus card, are rfid electronic security tags in real life application examples

• DNA security labels

DNA anti – counterfeiting technology is a new generation of more accurate anti – counterfeiting identification application technology.It directly utilizes the uniqueness and diversity of DNA genetic genes to extract, purify and sequence DNA into unique and authoritative sequences, so as to identify the authenticity of high-end technology.

• Double helix color code security labels

Double helix color code anti-counterfeiting technology is an upgrade product of anti-counterfeiting labels created on the traditional anti-counterfeiting label printing technology.

• Shape memory security labels

Polymer shape memory materials are used to produce anti-counterfeiting tags, anti-counterfeiting stickers, or other anti-counterfeiting products. As long as they are heated to a certain temperature, the text or pattern on the surface will immediately become another preset text or pattern, so as to check the authenticity of the product;

The advantages of polymer shape memory materials for anti-counterfeiting lie in:

(1) Technical authority: macromolecule shape memory anti-counterfeiting technology has just started in China, and has obtained international patent protection, which is extremely difficult to imitate.

(2) Easy identification: for consumers, too complex, difficult to distinguish anti-counterfeiting products are adverse to consumer inspection.Polymer shape memory anti-counterfeiting products can fully meet the requirements of “common sense, can be recognized by the senses” first line of anti-counterfeiting, consumers only need a cup of hot water or a lighter, within 5 seconds to identify the authenticity of the product.

(3) Full of magic fun: magic three-dimensional shape changes, making the inspection process very interesting.
