Consumers desire dent-free packages and properly affixed labels on 3D rigid packaging. A client seeks an automated system that will check the quality of these labels, and will detect, measure, and record critical information. The detection procedure will inform changes in processes, materials, or equipment to reduce or eliminate the imperfections. Such technology would first be applied for off-line lab tests, and then ideally be scaled for use in an online packaging system; the system will require real-time monitoring during packaging production. The equipment must detect defects as small as 2 mm.
