EAN 8
The EAN 8 bar code is related to the Universal Product Code (UPC) group.
EAN 8 can be printed with or without a 2- or 5-digit add-on data field, which is
placed at the end of the bar code. The EAN 8 (European Article Number) bar
code structure is shown in Figure 12 and described on the following pages.
Figure 12. EAN 8 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. A trailing quiet zone is provided automatically if an add-on
code has been specified in the bar code command.
Start/Center/Stop Codes
The Start/Center/Stop codes are special character codes marking those
portions of the bar code. These codes are produced with each bar code.
Data Field
The bar code symbol uses a series of varying width bars and spaces to
represent a limited numeric character set (numbers 0-9 and Special
Characters Start, Center, and Stop). The bars and spaces vary in width from 1
through 4 modules. Each character consists of 2 bars and 2 spaces that total
7 modules. The symbol coding of the left data field is different from the right
data field to permit read direction sensing.
