While printed labels provide important information about a product, they are not in themselves reliable proof of authenticity. We explain how to turn printed codes into tamper-proof product labels.
One thing is certain, authenticity labels must not be easily copied. This protection against counterfeiting is guaranteed when identifiers such as serial numbers are also equipped with physical security features. Simple embossed holograms are, generally speaking, not suitable for this (see the blog post Holograms as a security marking? What to look for).
Physical security markings produced using inaccessible, patented technologies are ideal. This ensures that only the manufacturer of these markings, and the brand owner as its client, have access to it. Counterfeiters are left with nothing.
These physical markings protect printed codes from copying by repeating the printed code or parts of it. In addition, the physical labels are composed of multiple layers with different security features. Some of these features are visible to the naked eye, while others can only be read with the help of a magnifying glass or special reading device. Accordingly, these features can be checked by different user groups: consumers, retailers, customs officials or a brand owner’s own experts.
Combining printed codes and physical security features reliably distinguishes products as originals. At the same time, this ensures that the product information displayed is correct.
