Barcode Test LLC is built on the people who come to us and the questions they ask. Although the questions are not all the same, there are common themes. Beyond the specifics, the overarching themes are confusion, overwhelm, frustration, and fear. I am deeply familiar with these themes, and as a younger person, I sometimes added embarrassment to the equation. Not helpful.
An older person may remember with compassion. Those themes can be painful, but they are also opportunities to learn. That is our mission. Here are some recent encounters.
Questions from a printer. Our customer says they are having problems with their barcodes, but we printed them exactly as they specified. How do we resolve this?
The solution begins with another question. Do you want to solve the barcode problem, or do you want to determine who is responsible? If you and your customer are partners with a common goal, the barcode is a problem you share. Focus on the solution, learn together, and move forward.
Questions from a brand owner. The barcodes from one of our label vendors work fine, but the exact same label from our other label vendor doesn’t. What’s wrong?
The solution always begins with the verification reports. If two different verifier brands are involved, it gets more complicated, but not impossible to sort. Start with what’s known:
- Confirm that the two labels appear to be identical—same barcode?
- Did both vendors print from the same barcode design file?
- What ISO parameters are different? Obviously, they differ—but how?
The responses should resolve the mystery.
Questions about verifier discrepancies. Company A has an XYZ verifier and Company B has an ABC verifier, and they disagree. Which one do you trust?
Egos and emotions are unhelpful in this situation. The worst possible solution is a “second opinion” from a smartphone, the idea being “..we’ll believe the verifier that the smartphone agrees with.” Smartphones can read almost anything but tell you nothing about ISO standards compliance. Without that, the liability is all yours.
Questions We Ask.
Oh yes, when we test barcodes for a client, we ask a lot of questions too. And not just when there are problems with the barcode. There are important questions to be resolved even when the barcode works perfectly. Here are some recent ones.
Questions to a Medical Device Manufacturer. You send us primary packaging labels and secondary packaging labels to test, but the barcodes are all the same size. Are you aware that the .0100” squares in the Data Matrix barcodes on your primary labels are too small for your secondary labels?
One client confirmed that their customer had specified these settings. Other clients were unaware of these settings and determined to check with their customers.
Questions about Barcode Discrepancies. Here are some questions we ask clients, when seemingly identical barcodes get different verification grades:
- Did you notice that the print gain in the passing barcodes is much lower than in the failing barcodes?
- Did you notice that the barcodes on some of your medical device labels have encoded the parentheses around the Application Identifiers?
- Your GTIN12 (UPC) barcode passes all of the ISO parameters but gets a failing symbol grade. Did you notice that it is smaller than the 80% minimum magnification?
At the end of the day, it’s always all about questions. Your questions and comments are welcome. Contact us here.
