Figure 26. UPCSHIP Structure
Quiet Zone
Both ends of the bar code structure have blank quiet zones. The quiet zones
should be at least 0.25 inches wide and completely blank to ensure accurate
reading of the start/stop codes and to prevent adjacent bar codes from
overlapping. You are responsible for providing sufficient space on the form for
the quiet zones.
Start/Stop Codes
Unique start and stop codes permit bidirectional scanning. Both start and stop
codes contain bars and spaces. They are automatically produced.
Data Field
The bar code symbol uses a series of wide and narrow bars and spaces to
represent numeric characters. The structure is 2 wide elements (bars or
spaces) and 3 narrow elements.
