Paper for MICR Documents
This standard establishes paper specifications for the MICR documents that are used in the US Payments System. While checks, substitute checks (IRDs) and deposit tickets are the primary documents considered in these specifications, users of MICR/OCR E-13B font readers will be well served by applying these specifications to internal documents, when intended for use in reader/sorters.
