Changing the threshold values for Right and Left space margins
When a bar code symbol is printed inside quadrangle, scanning may not be possible because there
is not sufficient left side and/or right side marginal space (see Table 3.43). By making change on
the left/right marginal threshold values, scanning a bar code symbol becomes possible.

When the left marginal space is
narrow.
When the right marginal space is
narrow.
When both right and left
marginal spaces are narrow.
Changing the thickness of bars of bar code symbol
If bars of a bar code are printed thick because blurring or scratchy white bars (spaces between two
bars) are printed thinly, the bar ratio will not be correct causing scanning incorrectly. By adjusting
the thickness of these bars makes scanning the bar code possible. This method is applicable if all
bars of a bar code are either too thick or too thin because the method is applied to the whole of a
bar code.
