Barcode Scanning

Each barcode format has certain requirements and guidelines for printing which improve the scanning of the barcode. Before project deployment, the barcode should be tested in the environment it will be scanned in to ensure the desired performance level is met.

Best Practices

The following are the best practices to improve the scan performance of a barcode:

  • Black barcode on a white background (high contrast); colored barcodes have less contrast
  • Large dimension barcode; smaller barcodes are not as reliable
  • High resolution artwork
  • Enough quiet space
  • High error correction level
  • Standard barcode formats; any modifications to the format specification can cause problems
  • Placed on a smooth surface; the scanner needs a clear, flat view of the barcode
  • Positioned so that the scanner can view the barcode straight-on
