Clear Zone

The bar code structure requires a completely blank, 1/4±inch wide, 5/8±inch tall clear zone, reserved for only the appropriate FIM pattern. Be sure to provide sufficient space for this zone.

Start/Stop Code

The start/stop code is a unique character identifying the leading and trailing end of the bar code. The start/stop code is automatically produced with each bar code. The start/stop code structure permits bidirectional bar code scanning.

Data Field

The bar code symbol uses a nine±position bar/no±bar pattern of tall (full) bars of uniform height. Minimum height must be 5/8± inch ± 1/8±inch. (Bar height may be longer to wrap around the top of the envelope.) Minimum bar width is .031±inch ± .008±inch. Spacing (pitch) between each bar/no±bar must be 1/16±inch. Bar tilt (slant) can vary ± 5 degrees (relative to a line perpendicular to the top edge of the envelope).
