Hello Community, 

How do you guys test whether the report you generate is according to GS1 standard or at least the sizing metric?

Is there a way to ensure the barcode follows the rules when coding/setting it up?

    Hi

    1. There are online barcode validators available. You can generate an image of your barcode (e.g., by exporting the report to PDF or an image file) and upload it to websites like Online Barcode Validator. They will analyze the image and verify if the proportions are correct.
    2. The most reliable method is to print the report and scan it with a standard handheld barcode scanner. If it scans instantly from various angles, the sizing metrics are correct.
    3. Zoom into the PDF and measure the width of the narrow and wide bars. Their ratio should be exact (e.g., 2:1, 3:1, etc.).
