quiet zone

In barcode technology, a quiet zone is the blank margin on either side of a bar code that's used to tell the barcode reader where a barcode's symbology starts and stops. The purpose of a quiet zone is to prevent the reader from picking up information that does not pertain to the bar code that is being scanned. (The blank margin will not send a scanning signal, hence the name "quiet".) As a rule, the quiet zone should be ten times the dimension of the narrowest element in the bar code ( X dimension ) or 1/4 inch, whichever is greater. An undersize quiet zone may render a bar code unreadable, or readable only in one direction.

You may cut the quiet zones for your own purpose, but it might cause reading problems, since a minimum 10x quiet zones are required by most of the linear bar code specifications. Some application can <a href="http://www.yiigo.com/guides/vbnet/how-to-generate-barcode.shtml
