Introduction
GB/T 37236—2018 Standard Background and Significance
GB/T 37236—2018 Technical Specification for Special Document Identification was proposed and coordinated by the Ministry of Justice, aiming to provide a scientific technical basis for the field of judicial identification. This standard combines multidisciplinary knowledge, including anti-counterfeiting technology, printing technology and document material analysis, filling the gap in the field of special document identification in China.
Definition and Classification of Special Documents
| Category | Definition | Example |
|---|---|---|
| Currency | Equivalents that are mandatory for use by law, including banknotes and coins. | RMB, USD, EUR |
| Certificate | Documents used to prove personal identity or rights. | ID card, passport, driver's license |
| Bill | Written evidence used to pay an amount or record a debt. | Check, bill, invoice |
| Trademark | A mark used to distinguish the source of goods or services. | Brand LOGO, product identification |
Core technology for special document identification
Special document identification relies on a variety of advanced technologies, including:
- Infrared inspection: used to detect the reflection characteristics of materials to infrared light.
- Ultraviolet inspection: using ultraviolet light to stimulate fluorescence characteristics.
- Microprinting: observing extremely fine text or patterns through a microscope.
- Chemical analysis: using reagents to detect the solubility characteristics of ink.
The evolution and comparison of anti-counterfeiting technology
| Anti-counterfeiting technology | Characteristics | Application areas |
|---|---|---|
| Optically variable ink | Changes color when the angle changes. | Credit cards, currency |
| Holographic anti-counterfeiting | Has three-dimensional effect and dynamic vision. | ID cards, passports |
| Magnetic ink | Can be read by magnetic devices. | Checks, trademarks anti-counterfeiting |
| Thermosensitive ink | Develops color when heated. | Tickets, invoices |
Implementation suggestions and precautions
Case analysis:When identifying a suspected forged ID card, first check its watermark, security thread and fluorescent reaction. If the watermark outline is blurred or lacks three-dimensionality, it may be a counterfeit.
Operational suggestions:
- Ensure that the detection equipment is calibrated regularly.
- Establish a standard sample database for quick comparison.
- Train identification personnel to grasp the latest anti-counterfeiting technology trends.
