Codabar
The character complement of the Codabar (Monarch) code comprises:
– 10 digits: 0 1 2 3 4 5 6 7 8 9
– 6 special characters: - $ : / . +
– Start/stop characters: a/t, b/n, c/*, d/e
The number of characters is variable. The start/stop characters are programmed with the
characters a/t, b/n, c/*, d/e. In the plain text line these characters are printed for star t/stop.
The symbol layout is self-checking. A check digit is not required and is rarely used. The
check digit must be programmed in the application.
The check digit method is modulo 16. In practice, modulo 10 with a weighting of 3 or modulo
11 are also used.
The ratio of wide to narrow elements should be between 2.0 and 3.0. A ratio of 2.5 is recom-
mended for applications.
The barcode height should be 25% of the barcode length or 20 mm, whichever is greater.
The blank zone before and after the barcode symbol should be at least 10 times th e width
of a narrow element.
