Use these parameters to define the width of the printability gauges (“H” marks) either side of your barcode. Smax defines the width of the left “H”, Smin defines the width of the right “H”. Enter 0 in both fields if you don't want printability gauges.
In the example below, the top barcode has a value of 0 for both Smax and Smin, the middle one has a value of
4 and the bottom one has a value
of 8 (the maximum).
