Anti-counterfeit labels often exist in the form of self-adhesive labels, which are currently widely used in all walks of life. As labels with independent functions, anti-counterfeiting labels range from comprehensive anti-counterfeiting stickers with extremely high security to small single-function waterproof warning mobile phone warranty labels. They all have certain functions such as anti-counterfeiting, anti-stripping and security management.
1. Anti-counterfeit label design elements
â‘ In a limited space, including all text,
â‘¡ Including various text and image features designed to prevent forgery,
â‘¢ Use as many crafts as possible in a small space,
â‘£ Reduce the production and management difficulties caused by the use of anti-counterfeit labels, and even cost outlays.
2. Anti-counterfeit label function design label is not a simple stacking of some different technologies and design methods. It is completed by expert design working groups such as raw materials, anti-counterfeiting technology, printing technology, ink and so on. Although we cannot prevent counterfeiting, if we adopt high technology that is difficult to imitate, and promote the knowledge of identifying genuine and fake products to consumers, it can play a role in curbing counterfeiting. Anti-counterfeit labels should comply with certain design principles:
â‘ Choose a special design that can be clearly distinguished even if it is copied,
â‘¡ Choose production methods that are difficult to forge and costly to invest in,
â‘¢ Make full use of the methods that consumers have mastered or easy to learn to identify the authenticity to perfect the anti-counterfeiting design.
The following main functional designs are often used in anti-counterfeit label design to achieve the purpose of anti-counterfeiting.
1) Label shading design â‘ The anti-counterfeit lines and patterns used have length, location, density and density. Changes in thickness and color are difficult to imitate.
â‘¡ It is easy to distinguish, and genuine and fake products can be distinguished only by visual inspection or magnifying glass.
â‘¢ Prevent scanning and printing. All lines of the precise shading are composed of solid lines, and the imitation products scanned and separated and printed are composed of dots, which can be seen at a glance.
â‘£ Patterns made of complex lines are impossible to make by hand.
2) Tamper-evident function design â‘ Through corresponding technical treatment, the label has mechanical characteristics in different directions, which is very easy to damage when it is lifted,
â‘¡ Use fragile paper materials, raw materials for uncovering words, and raw materials for preventing foam from uncovering etc.
3) Anti-channeling function design
Print the name of the distribution area, area management code, anti-counterfeiting code on the label, and even identify the inquiry telephone and other information.
4) Design of anti-scanning copy function â‘ Select special paper, such as watermark paper, fiber silk paper, paper with security thread, etc.,
â‘¡ Use special inks, such as optically variable inks. Pearlescent ink, photosensitive ink, water-sensitive ink. Thermal ink, infrared ink. UV ink. Magnetic ink, etc.,
â‘¢ Use special printing process, such as gravure printing, embossing printing, holographic hot stamping, hot refraction treatment, etc.
â‘£ Use special design, such as safety shading design. Disturbance invisible graphics and graphic design and other high-security design.
At present, there are more than ten types of anti-counterfeit labels commonly used in packaging.
1. An uncovered self-adhesive anti-counterfeiting seal with a plastic film as the base material for the anti-tamper seal. The colorless and non-sticky self-adhesive plastic strip before it is lifted; after lifting, the colored handwriting can be seen on the paper and on the plastic strip To the obvious colorless writing, it has the characteristics of one-off loss and one-off loss. It is mostly used in anti-counterfeit envelopes, electrical appliance warranty labels and other fields.
2. The fragile paper label uses special fragile paper or fragile self-adhesive materials, on which trademarks, text descriptions and barcodes can be printed, and cannot be fully lifted after being pasted on the packaging. Once lifted, the paper will be broken.
3. Comprehensive anti-counterfeiting and anti-crimping paper labels use a variety of anti-counterfeiting technologies to make self-adhesive paper labels, which can enhance the anti-counterfeiting function. In order to prevent the label from being lifted, replaced and reused, die-cutting indentation technology can be used to partially prevent the label from being uncovered, and cannot be recovered after being lifted.
4. There are many types of bar codes currently used in bar code technology labels. Anti-counterfeit bar codes mainly include one-dimensional bar codes and two-dimensional bar codes. Bar code technology can not only promote better and faster application, but also achieve the purpose of preventing famous products from being counterfeited and protecting the interests of consumers.
5. Laser holographic image label The application of laser holographic image technology in anti-counterfeiting packaging is mainly to print anti-counterfeiting labels and trademarks. The factors that affect the anti-counterfeiting performance of laser holographic labels are the types and locations of labels. The types of anti-counterfeiting labels for laser holographic images are as follows.
â‘ The self-adhesive type makes the holographic anti-counterfeit graphic on the self-adhesive material, without using any adhesive when using, it has good adaptability to the machine. The biggest shortcoming is that it can be used repeatedly, and criminals can use old packaging and labels to make fakes.
â‘¡ The tamper-evident type makes up for the shortcomings of ordinary self-adhesive labels. When the label is removed from the packaging, the holographic image of the label is unrecognizable and cannot be used again, which can prevent the use of old labels to make fakes.
â‘¢ The hot stamping type is a kind of holographic anti-counterfeiting label that cannot be removed. The holographic anti-counterfeiting label is hot stamped onto the packaging material by a hot stamping machine, and integrated with it.
6. The font anti-counterfeit polyester film label is made of aluminum foil without words and self-adhesive strips before being lifted. After being lifted, there are obvious colored handwritings on the label paper and packaging materials.
7. The transparent PVC anti-tamper general label is a white, non-sticky self-adhesive film label before being lifted. After being lifted, there are obvious colored handwriting on the label and packaging materials.
8. Transparent PVC anti-counterfeit labels On the self-adhesive labels or other documents, the transparent laser holographic film with personalized information is attached, which does not affect the overall design and original effect, but also adds anti-counterfeiting functions to make the label personalized.
9. The foam film label is a unique semi-gloss white film, which is composed of two layers of polystyrene film. The surface layer is a transparent film, suitable for printing; the lower layer is a white foam film that has been expanded. Use permanent acrylic adhesive. It has a good security and anti-counterfeiting effect. When the label is attached to the substrate and then lifted off, the two layers of film are separated, the label is torn, and the residue of the foam layer will be left on the packaging, which is difficult to remove. Suitable for use in humid environments, especially in the production and packaging of beverages, dairy products and other products, it has extraordinary practical value. Suitable for safety labels for glass, PVC, polystyrene bottles and glazing cartons.
10. The paper base partially uncovered label The label base material is coated paper (special paper can also be used), and it is printed with gravure, letterpress and offset. Just uncover the upper part, and the bottom layer will have data for consumers to enter and query. The label is not reusable. When used as a seal, it is firmly attached and not easy to fall off.
11. The rule-disclosed composite anti-counterfeiting label is a self-adhesive anti-counterfeiting label. When in use, the label is directly attached to the product; when it is recognized, the label is uncovered, and a pre-designed invisible graphic and positive image will be left on the package; the invisible graphic and negative image will be removed on the label. Materials such as holographic film, coated paper, and plastic film can be used as the surface material.
