ISO 1004-2

Description / Abstract: This part of ISO 1004 specifies the shapes, dimensions and tolerances for the 10 digits 0 to 9, five symbols, and 26 letters, to be printed with magnetic ink for the purpose of character recognition. It describes the various types of printing defects and other printing considerations, together with the tolerances permitted, and also contains specifications to signal level measurement.

The characters specified in Clause 4 of this part of ISO 1004 were developed initially for use in banks to permit automatic document handling for bank data processing, but they have application to other automatic processing systems as well.
