Quiet Zone
When you estimate the area you'll need for the bar code, remember to add the length of the quiet zone. The quiet zone is an area of white space required at the beginning and end of each bar code. The minimum size of the quiet zone is 0.10, or 10 times the width of the narrowest bar code element, whichever is greater. The tables below show the minimum size of the quiet zone at each density. For wand scanning, the quiet zone should be 0.25 to 0.35 inch.
Density | Quiet Zone |
10.10 inch
20.15 inch
30.20 inch
The minimum quiet zone for parallel bar codes printed on the 9465 are shown in the following table.
