Question: When will I get my report?
Answer: Time taken to generate a report varies depending on current workload; generally it is between – seven working days.

Question: Why did my report fail?
Answer: The barcode could have failed for any number of reasons, the most common being the height of the barcode was insufficient or the Quiet Zone (solid, light area to the left and right of the barcode) is insufficient. Page of the report gives a detailed overview of why your barcode failed. It will give you a detailed explanation of the parameter(s) that failed and make recommendations as to how to rectify the problem.

Question: I had a novel idea for a barcode and produced a small test run on which the barcodes passed verification. Then I did a production run and the barcodes failed. What went wrong?
Answer: Every print run produces a whole new barcode because it will involve at least some things being different from the previous run. Even if the same equipment and materials are used, there will be minute differences in machine settings, perhaps in the batch or mix of inks, the paper or other substrate, or just the ambient humidity or temperature. Verification also tests the reflective properties of the paper and ink and even subtle changes in these can affect the results. There is always the possibility of changes between test samples and production runs so when testing samples, you always need to look for a clear pass. Marginal passes mean that going ahead with a full run could be a risk.

Question: Why do I almost always get different results on consecutive verification tests of the same barcode? Can I rely on the results?
Answer: Verifiers report very accurately. However, each result is based on ten scans of the sample being tested and you will never get precisely the same ten ‘slices’ of barcode on consecutive scans. Some variation in the results is inevitable although they should consistently show that the same barcode either passes or fails the test. If you get results that hover around the pass/fail threshold it means that your barcode is of very marginal quality and needs improvement.

Question: When do I need to change a Global Trade Item Number (GTIN)?
Answer: A separate unique GTIN is required whenever any of the pre-defined characteristics of an item are different in any way that is relevant to the trading process. The guiding principle is if the customer is expected to distinguish a new trade item from an old trade item and purchase accordingly, a new GTIN should be assigned. It is strongly recommended that someone within your company be assigned to manage the allocation of GTIN's and keep accurate and updated records of the numbers created to avoid duplication.
