Validation is checking that a barcode is present, can be scanned, and matches the barcode expected during a particular production batch. Verification is measuring and grading the quality of a printed barcode according to international ISO/IEC standards, and is a more rigorous process.
Axicon’s Checkrite validators are not intended to replace barcode verification, but they are a very useful check on the correct barcode labelling or printing on any production line, as every barcode will be scanned.
The Checkrite validators are stand-alone systems that are fitted to a production line, and they comprise a control box, a scanner and a sensor. They are PLC (programmable logic controller) based systems that can provide a visual indication of the validity of a barcode, as well as halt the line if an incorrect barcode is scanned.
Before starting a production batch, a correct barcode is scanned and all subsequent barcodes must match this first one. If a different barcode is scanned, a red warning light will show, and the system can trigger an ejector arm, audible warning or line-stop. Missing or unscannable barcodes will prompt an amber warning light. A constant green light means everything is all right.
The Checkrite 5 is supplied in a steel or stainless-steel housing, while the Checkrite 7 has a stainless-steel housing. Stainless-steel enclosures for the scanners can also be provided if these are required for hose-down areas.
