According to information released by the China National Intellectual Property Administration (CNIPA), Wenzhou Haoge Anti-Counterfeiting Technology Co., Ltd. has been officially granted a utility model patent titled “Dynamic Color-Code Anti-Counterfeiting Label”, with authorization number CN 222354608 U. The patent application was submitted in May 2024.
The approval marks another important milestone in Haoge’s ongoing development of practical, cost-efficient, and highly effective security printing technologies.
Innovative Design Combining Simplicity and Security
The patented anti-counterfeiting label features a structurally optimized design centered around a dynamic color-code verification mechanism. The label consists of a main body incorporating a recessed compartment, secured with a positioning mesh and protected by a transparent outer layer.
Within the compartment, an ink capsule is embedded and coated with a colored anti-counterfeiting code layer. The system is activated through an integrated tamper-evident pull strip, which contains a precision cutting element. When the pull strip is engaged, the ink capsule is ruptured, triggering a visible color-change verification effect.
To further enhance security, the pull strip includes a dedicated anti-counterfeiting groove coated with a photochromic color-changing material, adding an additional layer of visual authentication.
Practical Advantages for Large-Scale Applications
According to the patent description, this solution offers several key advantages:
- Simple structural design
- Low manufacturing cost
- Clear and intuitive verification
- Strong resistance to counterfeiting
- High practicality for mass production
These characteristics make the technology particularly suitable for high-volume, cost-sensitive security applications, where both reliability and scalability are essential.
Expanding Applications in Controlled-Value Printing
Dynamic color-change verification technologies play an increasingly important role in modern security printing. Their ability to deliver instant visual feedback makes them ideal for applications that require one-time verification, tamper evidence, and fraud prevention.
Haoge’s patented solution provides a flexible technical foundation that can be extended beyond traditional anti-counterfeit labels to other controlled-value printed products, such as scratch lottery tickets, promotional game cards, and verification-based packaging, where user interaction and authentication integrity are critical.
Strengthening Intellectual Property and Industry Responsibility
The granting of this patent reflects Haoge’s continued investment in independent innovation and intellectual property protection. More importantly, it reinforces the company’s responsibility to deliver secure, practical, and scalable anti-counterfeiting solutions to brand owners and institutional clients.
As security threats evolve, Haoge remains committed to advancing technology-driven solutions that balance manufacturing efficiency, cost control, and robust authentication performance.
