Postal services. Automatic identification of items. Two dimensional bar code symbol print quality specification for machine readable Digital Postage Marks
This document:
These provisions apply to the Digital Postage Mark blocks as they appear on fully produced mail items when remitted to postal operators, including the characteristics resulting from operations other than printing per se that affect their appearance to a mail processing system (covering, inserts into transparent window envelopes, affixed Digital Postage Mark labels).
This document does not define the qualification tests or sampling requirements necessary to determine the practical feasibility of any specific read rate.
Although this document is not intended for barcodes (other than Digital Postal Marks) which can be printed on mail pieces for item identification or additional services, a similar methodology can be applied.
