Global Vision's BarProof™ automatically locates all barcodes on a label,carton or press sheet, and grades each barcode according to CEN/ANSI/ISO standards.
Verify & decode linear 1D & 2D barcodes
Barcode verification is your insurance policy for the highest quality barcode in your supply chain, thus enhancing your supplier customer relationship.
A barcode that is ‘read’ with a wand gives no guarantee that it will be readable with another wand, nor that it can be properly verified. In addition, a barcode reader might tell you that your barcode is unreadable, but it won’t identify the problem.
Our Barcode Verifier takes precise measurements of each individual bar, and qualifies each barcode from A to F based on the grading criteria below. By knowing a barcode grade, you will know which corrective action you need to take, if any.
Decode – Checks if the scan line data can pass the reference decode algorithm
Symbol Contrast – Checks the difference between the minimum and maximum reflectance of the scan line
Minimum Reflectance – Checks that the minimum reflectance is less than half of the maximum reflectance
Minimum Edge Contrast – Checks the smallest edge contrast found in the scan line
Modulation – Checks the ratio of the minimum edge contrast to the symbol contrast
Defects – Checks for reflectance non-uniformity along the scan line
Decodability – Checks the accuracy of the barcode printing and image in relation to the appropriate symbology reference decode algorithm
