1D Linear Decode Zones
Figure A-1 shows the decode zone for the 1D linear scan engine. The figures are typical values. Table A-2 lists
the typical 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.
