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.
