The MSI structure is shown in Figure 21 and described on the following 
pages.

Both ends of the bar code structure require 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.
