Checking Quiet Zones

Quiet zones are the white spaces surrounding the bar code. Each bar code requires a minimum quiet zone distance in order for the bar code to be scanned properly.

NOTE: The validator requires a minimum distance of 1/2” or 20 times the minimum element width (x-dimension), whichever is greater, between bar codes.

When the Quiet Zones parameter is enabled, then the bar code quiet zone is included as part of the pass/fail criteria.
