Abstract
A technique for compensating for systematic errors in printing or reading bar codes is disclosed. Label decoding always begins with a center character and proceeds one character at a time toward a margin. When bar-space pair measurements indicate an ambiguous character (which can only be fully decoded using bar width measurements) error correction is based on the characteristics of the adjacent, previously decoded character.
