Introduction
Standard Revision Background and Technological Evolution
GB/T18758-2025, "General Technical Requirements for Particle Track Anti-Counterfeiting Technology Products," marks the first major revision of the 2002 version of the standard and incorporates the technical content of GB/T20205-2006, "Heavy Ion Microporous Anti-Counterfeiting Labeling." This revision reflects the rapid development and increased maturity of particle track anti-counterfeiting technology over the past two decades.
The core changes in the standard revision are reflected in the improvement of the technical framework and the standardization of testing methods. The "Anti-Counterfeiting Strength" section from the original standard has been deleted, and its requirements have been integrated into the framework of GB/T19425-2025, reflecting the harmonization of the standard system. Furthermore, requirements for emerging technologies such as ion beam spectral signature encoding technology have been added, reflecting the latest trends in technological development.

Detailed Explanation of Key Technical Requirements
Appearance Quality Requirements
The standard sets clear requirements for the appearance quality of particle track anti-counterfeiting products: the pattern area must not have spots or stains with a diameter greater than 0.5mm, and color misalignment must be controlled within 0.15mm. These requirements ensure the visual recognition and aesthetics of the anti-counterfeiting mark.
Physical performance indicators
Different types of particle track anti-counterfeiting products have differentiated physical performance requirements:
- Nuclear track anti-counterfeiting technology products: signal-to-noise ratio ≥10:1
- Heavy ion track anti-counterfeiting technology products: micropore density 2×10⁴/cm²～1×10⁶/cm², pore size 0.5μm～10μm
- Ion beam sputtering deposition coating technology products: film uniformity ±2%, resistance temperature variation coefficient ≤5×10⁻⁶/℃
Anti-counterfeiting identification features
The standard stipulates three main types of anti-counterfeiting identification features: explicit micropore pattern recognition, physical property change recognition, and spectral feature coding recognition. Among them, ion beam spectral feature coding technology products require unique spectral graphic coding, which provides a technical basis for digital anti-counterfeiting.
Test methods and instrument requirements
| Test items | Test methods | Instruments and equipment | Accuracy requirements |
|---|---|---|---|
| Micropore aperture measurement | Optical microscope observation | Precision optical microscope | 0.5μm |
| Thin film uniformity detection | Step profiler measurement | Film thickness tester | ±1 Implementation Recommendations and PrecautionsProduction Process ControlManufacturers should establish a comprehensive production process control system, especially for the control of pattern line width and spacing of ion beam etching technology products. Achieving a processing accuracy of <2μm requires advanced ion beam processing equipment and strict environmental control. Quality Inspection SystemIt is recommended that companies establish a three-level inspection system in accordance with the inspection rules required by the standard: raw material inspection, process inspection, and final product inspection. Statistical process control (SPC) is performed on the micropore density and pore size of heavy ion track anti-counterfeiting products to ensure product quality stability. Particle track anti-counterfeiting technology involves patented technology and trade secrets. Enterprises should establish a technical security and confidentiality system in accordance with the requirements of GB/T17002. In particular, strict access control measures should be implemented for the encoding algorithm and database management of ion beam spectral signature encoding technology. The implementation of GB/T18758-2025 will have a profound impact on the anti-counterfeiting industry: on the one hand, it standardizes the technical requirements and testing methods for particle track anti-counterfeiting products, raising the industry's entry threshold; on the other hand, it promotes the research and development and application of new technologies. In particular, the standardization of ion beam spectral signature encoding technology will promote the integration and innovation of digital and traditional physical anti-counterfeiting. The release and implementation of this standard marks a new stage in the normalization and standardization of particle track anti-counterfeiting technology in my country, providing important support for the quality improvement and technological innovation of anti-counterfeiting products. Enterprises should promptly study and implement the requirements of the standard, strengthen technological research and development, and enhance product competitiveness.
