Product marking is often treated as a late step in the delivery process, but in many operational contexts it plays a critical role in identification, traceability, and serviceability. Poorly designed or poorly verified markings can lead to misidentification, scanning failures, and operational inefficiencies long after the product has left production.
Standards such as ISO/IEC 15415 define quality criteria for 2D codes like DataMatrix, but compliance alone is not always sufficient. Markings must also be designed for the real environment in which the product will be used. Factors such as surface material, wear, contamination, lighting conditions, and accessibility all affect long-term readability.
Verification should therefore be seen as part of quality assurance, not just as a formal requirement. By verifying marking quality early and understanding how markings perform in realistic conditions, organisations can reduce downstream issues related to maintenance, documentation, and product identification. In the long run, consistent marking quality supports more reliable traceability and reduces the risk of costly rework or customer non-conformities.
