- 2. 1 About Barcodes Standards What Are ISO Barcodes Standards? What Are Types Of ISO Barcodes Standards? What Are GS1 Barcodes Standards? What Barcode Types Does GS1 Set Standards For? 2 3 4 5 barcodelive.org
- 3. Businesses & organizations are constantly producing barcodes Consistency is required to simplify the flow of information in supply chain => Standards are created barcodelive.org
- 5. ISO stands for International Organization for Standardization "A standard is a document that provides requirements, specifications, guidelines or characteristics that can be used consistently to ensure that materials, products, processes & services are fit for their purpose" barcodelive.org
- 6. There are 3 ISO standards that address barcode quality ISO 15416 for 1D barcodes ISO 15415 for 2D label-based barcodes ISO/IEC TR 29158, or AIM DPM for 2D DPM codes barcodelive.org
- 8. This ISO standard is for 1D barcodes If a scan line fails minimum reflectance, decoding, or minimum edge contrast, a "F" grade is automatically assigned If all 3 pass, the program ranks the parameters of symbol contrast, modulation, flaws, and decodability barcodelive.org
- 9. Minimum Reflectance Edge Contrast Modulation Decode Defects Decodability Check if the bars are dark enough to meet the required ratio of light reflected off of the spaces. Measure difference between adjacent bars & spaces Refer to local variations in contrast Check if the code can be read using standard reference decode algorithm Include printing errors, dirt, or markings that affect one single bar or space Grade the accuracy of bar and space widths compared to their ideal size barcodelive.org
- 10. This ISO standard evaluates 2D barcodes The grading procedure begins with a pass/fail test. If the code can be decoded, the first condition is passed If it cannot, it is automatically given a "F" barcodelive.org
- 11. Symbol Contrast Modulation Fixed Pattern Damage Axial Non- uniformity Grid Non- uniformity Refer to the difference between the darkest & lightest modules Measure local variations in contrast Include errors with the L sides or clock pattern or quiet zone Refer to the uneven scaling of the code Measure the biggest deviation from the grid barcodelive.org
- 12. The quality parameters and grading process for DPM codes are similar to ISO 15415 AIM DPM calculates global threshold using a more sophisticated algorithm than ISO 15415 to accommodate a wide range of background surfaces barcodelive.org
