The decode zone is a function of various symbol characteristics including density, print contrast, wide to narrow
ratio and edge acurity. Typical values are shown.

and
and guaranteed distances for selected bar code densities. The minimum element width (or “symbol density”) is the
width in mils of the narrowest element (bar or space) in the symbol. The maximum usable length of a symbol at any
given range is shown below. To calculate this distance, see
width in mils of the narrowest element (bar or space) in the symbol. The maximum usable length of a symbol at any
