4.2.1 UCC/EAN-128 specications
The UCC/EAN-128 specication is an internationally recognized format for application
identiers in code 128 bar codes. The bar code symbology is identical to Code 128.
These identiers are not intended for point-of-sale applications. Only recognized
bodies of the UCC or EAN may assign application identiers. More information may
be found at:
http://www.ean.be/ for the EAN and
http://www.uc-council.org/ for the UCC
EAN 128 EXAMPLES:
Print all-numeric bar code “1234”, 5mm high, with human readable text in EAN-128
format:
n1 = 1 start character + EAN specied + 4 printed characters = 6
L = 5mm / 0.125mm = #40
start character = START C (numeric pairs) = #137
