適用范圍：This International Standard:- specifies a methodology for the measurement of defined print quality attributes of Digital Postage Marksin the form of two-dimensional bar code symbols on mail-pieces,- defines methods for grading the results of these measurements and deriving an overall symbol qualitygrade as a guide to estimating the readability of the Digital Postage Marks,- provides guidelines for printing and gives information on possible causes of deviation from high grades toassist users in taking appropriate corrective action,- defines a test procedure for the assessment of printing systems for the production of Digital PostageMarks.These provisions apply to the Digital Postage Mark blocks as they appear on fully produced mail items whenremitted to postal operators, including the characteristics resulting from operations other than printing per sethat affect their appearance to a mail processing system (covering, inserts into transparent window envelopes,affixed Digital Postage Mark labels).This International Standard does not define the qualification tests or sampling requirements necessary todetermine the practical feasibility of any specific read rate.
