scope:
This standard describes nominal shapes, sizes, and printing positions of OCR-B alphanumeric characters and symbols for optical character recognition (OCR) systems.
Purpose. The purpose of this standard is to establish a standard character set and character specifications for use in optical character recognition systems. It is the further purpose of this standard to provide a character set in which the conventional appearance of the characters has not been compromised for purposes of increasing OCR distinguishability. In order to accommodate a wide variety of OCR applications, the character repertoire includes numerals, uppercase and lowercase characters, and special symbols in three different sizes.
