GS1 Thailand tests the barcode for compliance to the GS1 Standards through a verification process and the GS1 General Specifications. This testing assesses size, color, print quality, and quiet zones. GS1 Thailand also assesses barcode height, location/placement of the barcode, and the correct calculation of the check digit.
Barcode verification is the best way to ensure that your barcodes will scan the first time, every time. Poor quality barcodes may cost you time, productivity, and money.
Why not just use a scanner to check readability ?
Any two scanners aren’t the same:
The optical arrangements available for scanners vary widely.
Manufacturers of bar code readers build all kinds of clever features into their decode algorithms.
What to verify?
Parameters that can be measured visually, without equipment
Parameters that should be measured using verification equipment:
ISO Bar Code Print Quality Parameters or Scan Reflectance Profile Analysis (ISO/IEC 15416 – Barcode Print Quality and ISO/IEC 15415 Barcode Print Quality for 2D)

It takes about 5 working days to check GS1 & ISO/IEC parameters accurately.
