Label Inspection and Validation
High-speed labelling of products, ranging from bottles and cans, to tubs to boxes, can produce a wide variety of defects. These defects can lead to label errors that can be harmful to a brand or even present liability issues for a brand owner. Labels can be inspected for label presence, wrinkles, tears, skewed labels, double labels, flagged or missing labels, as well as incorrect label pairs on containers and packages.
Vision Inspection Solutions for label inspection can be set up to ensure perfect product presentation and confirm label ID every time. These automatically inspect labels on all packaging to detect and automatically reject packages and containers with label issues.
- Label Presence Verification: inspects for the absence or presence of a label on a package or container.
- Label Pair Validation: checks if the front and back labels are paired correctly.
- Skewed Label Detection: ensures that labels are applied straight, and in the correct position.
- Dog Ear Label Detection: verifies that labels have been securely applied to the container or package.
- Double Label Inspection: ensures that only one label has been applied to the same location on the package.
- Overwrap Alignment Inspection: ensures that wrap-around labels are straight and properly positioned. A 360-degree inspection on round bottles is also possible on production lines.
- Graphical Label Verification: inspects for a unique graphical item on the label to confirm that the proper label is being applied.
- 2D Data Matrix Code Verification: confirms that the proper label has been applied by verifying the 2D data matrix code is present, or that the code has been printed correctly.
- Barcode Verification: confirms that the proper label has been applied by verifying that the correct barcode is present, or that the code has been printed correctly.
When integrated with Matthews iDSnet, the solution can not only check label presence, but can also verify if it is the right label is applied, thereby eliminating any labelling errors.
