In-Sight ID readers and vision sensors now sport verification capabilities for IAQG ( International Aerospace Quality Group) Standard 9132 for Data Matrix codes and supplemental metrics for code readability. Verification is used at the marking station to identify missing or inconsistent code features that may affect readability. IAQG defines technical and quality requirements to assure that marking equipment applies dot-formed codes that meet established criteria for dot size, position, roundness, uniformity, and other qualities. Supplemental metrics extend these capabilities by assessing the readability of codes based on information such as background variation, image sharpness, and symbol and cell separability.
