What are the applications of A4 stickers in anti-counterfeiting technology?

The application of A4 stickers in anti-counterfeiting technology is very extensive, mainly reflected in the following aspects:

1、 Ink anti-counterfeiting technology

Photochromic ink

Characteristics: After printing, the ink will present different colors at different angles.

Application: Increasing the difficulty of anti-counterfeiting through special light transformation effects, commonly seen in anti-counterfeiting labels for high-end products.

invisible ink

Characteristics: Ink is colorless under normal light and develops color under specific light (such as ultraviolet).

Application: Suitable for printing secret marks. When identifying authenticity, use corresponding light to illuminate the secret mark area, and the font or pattern will appear.

2、 Material anti-counterfeiting technology

Fragile materials

Features: Low surface strength and tear resistance, once peeled off, it will damage the label.

Application: Usually used as a sealing label for packaging boxes to prevent the packaging from being recycled again.

Laser font anti-counterfeiting

Features: Special laser patterns are created on the surface of the material, and when the label is removed, the pattern will remain in the removed position.

Application: Due to the fact that laser patterns are usually customized and have high plate making costs, they are difficult to replicate and are suitable for anti-counterfeiting of high-end products.

3、 Printing anti-counterfeiting technology

Secret anti-counterfeiting and anti-counterfeiting thread technology

Secret anti-counterfeiting: Embedding tiny text or patterns during printing that are difficult for people to detect.

Anti counterfeiting thread technology: using special software to generate complex patterns that are difficult to imitate.

Application: These two technologies are commonly used for anti-counterfeiting of paper currency and also for anti-counterfeiting of adhesive labels.

Die cutting anti-counterfeiting

Characteristic: Adding a flower knife pattern on the die-cutting blade creates many irregular flower knife cuts on the surface of the label, making it difficult to fully remove.

Application: Simple process, affordable price, suitable for products with low cost requirements and low anti-counterfeiting requirements.

4、 Digital anti-counterfeiting technology

Database anti-counterfeiting

Features: Printing special variable numbers, consumers can distinguish authenticity through online or phone inquiries.

Application: Due to the huge investment in databases and high cost of counterfeiting, the anti-counterfeiting effect is significant, and it is commonly used in high-end tobacco and alcohol products.

Digital printing

Features: Perform partial debonding treatment on the adhesive surface of the self-adhesive material, and print variable QR codes or variable numbers.

Application: QR codes and numbers carry product information, which can prevent distributors from colluding and connect to databases to enhance anti-counterfeiting effectiveness.

5、 Other anti-counterfeiting technologies

In addition to the above technologies, A4 stickers can also use anti-counterfeiting techniques such as flower clusters, patterns, lace, latent images, reliefs, microforms, and anti scanning. By combining different lines, elements, and printing background patterns, various anti-counterfeiting effects can be produced.

In summary, A4 stickers have various applications in anti-counterfeiting technology. Enterprises can choose suitable anti-counterfeiting technologies or combine multiple anti-counterfeiting technologies according to the characteristics and needs of their products to improve their anti-counterfeiting performance and security.
