Things can be done faster and the chance of a number being wrong is reduced when it is read with a scanner rather than being entered manually. That the barcode is readable is a prerequisite for these flows to work.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Tips for good readability and reliable scanning<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><strong>Clean the printer heads<\/strong>&nbsp;<\/strong>thoroughly at regular intervals. If the printer is used intensively for labels, daily cleaning of the heads can be required. Check with your label printer supplier for maintenance advice.<\/li>\n\n\n\n<li><strong><strong>Check-scan the barcodes <\/strong><\/strong>continuously or selectively&nbsp;to ensure quality is maintained.<\/li>\n\n\n\n<li>Choose&nbsp;<strong>a label material of high-quality<\/strong>&nbsp;since this often pays off.<\/li>\n\n\n\n<li>Choose&nbsp;<strong>a label material which can tolerate wear and tear&nbsp;<\/strong>during handling, for example by rubbing, exposure to sunlight and wet without losing its readability.<\/li>\n\n\n\n<li><strong>A<strong>djust the barcode module width<\/strong>&nbsp;<\/strong>to the symbology, application and size of the item. Remember that greater module width gives better readability. For example, a pallet label is often scanned from a distance by a scanner fixed to a moving truck. A large module width will be required to ensure that the barcode can be scanned reliably.<\/li>\n\n\n\n<li><strong><strong>Adjust the barcode height<\/strong>&nbsp;<\/strong>to the symbology, application and size of the item. Remember that a small barcode height reduces readability.<\/li>\n\n\n\n<li><strong>Position the label as straight as possible<\/strong> because the label is often read with a fixed reader, which only emits a horizontal beam.<\/li>\n\n\n\n<li>Be sure to <strong>attach the label so that there are no creases.<\/strong> Folds on the label can make it impossible to read it.<\/li>\n\n\n\n<li>In order for the barcode to be readable there must always be a&nbsp;<strong>light margin<\/strong>&nbsp;to the left and right of the barcode\u2019s start and stop symbols. The light margin is an empty space which is needed so that adjacent information such as the package artwork will not interfere with reading.<\/li>\n<\/ul>\n\n\n\n<p><a href=\"https:\/\/gs1.se\/en\/capture\/\" data-type=\"page\" data-id=\"2846\" target=\"_blank\" rel=\"noreferrer noopener\">Learn more about GS1 barcode types<\/a><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Check barcode with GS1 BarcodeCheck<\/h2>\n\n\n\n<p>If you would like help checking that your barcode is of sufficiently high quality, you can use our service <a href=\"https:\/\/gs1.se\/en\/standards-and-services\/barcodecheck\/\" data-type=\"product\" data-id=\"3852\">GS1 BarcodeCheck<\/a>.

A number from 1 to 5 is used to grade the quality of the barcode. The method described in ISO\/IEC 15416 is technically aligned with ANSI which GS1 Sweden uses for barcode quality control. The ANSI standard uses the letters A to F to grade the quality of the barcode.
