Symbol Contrast
NOTE: This parameter factors into the Overall Grade (page 66).
The higher the value, the stricter the criterion for passing.
Symbol Contrast represents the contrast between the bars and
spaces in the bar code used by the validator for pass/fail threshold
used during the analysis of bar codes. The bar code must have a
certain level of contrast to be recognized by the validator. Bar
codes with a symbol contrast below the threshold will fail.
You can set the Symbol Contrast parameter to a percentage value
from 0% to 100%. The default is 0%.
NOTE: To disable this parameter, set Symbol Contrast to 0%.
