12、 for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has
13、the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The pro
14、cedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editor

19、2: Print specifications for CMC71 ScopeThis 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
20、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 th
21、ey have application to other automatic processing systems as well.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

30、widths are used: “long” and “short”. It is the combination of these “long” and “short” intervals that determines the character code.Two long and four short intervals may be combined in 15 possible ways (C62) a total which is available for the 10 digits and five symbols.The alphabetic code uses one o
31、r three long intervals, allowing a total of C61+ C63= 26 combinations which are thus available for 26 letters.Table1 shows the correspondence between codes and the characters. The intervals are numbered 1 to 6 from left to right on the printed character. Their values are represented by the digit 0 f
32、or short intervals and by the digit 1 for long intervals.4.2 ConfigurationThere are four font heights (see 10.1.5): 3,20 mm, 3,00 mm, 2,85 mm and 2,70 mm.

36、tification of the interval lengths between adjacent strokes. Stroke sensing takes place magnetically.6 Reference edges of documentsFor the purpose of measuring the printed image, the right-hand and the bottom edges are the reference edges of the document.7 Print location7.1 Horizontal locationThe ex
37、treme right mean edge of the printed line should be located at least 6,0 mm from the right reference edge of the document. The distance between the left-hand edge of the document and the extreme left mean edge in the printed line should be at least 4,0 mm. In some cases, by agreement between parties
38、 concerned, this latter distance may be reduced to 2,0 mm. System consideration may dictate a 6,0 mm minimum margin on both sides, if the document is to be readable in both directions. (See Figure 1).7.2 Vertical locationThe character shall be printed entirely within a printing band 6,4 mm high. The
39、 bottom edge of this printing band is located 4,8 mm above and parallel to the bottom reference edge of the document. (See Figure 1).This subclause does not apply to punched cards.8 Clear bandOver the whole length and on both sides of the document a clear band, 16 mm measured from the bottom edge of
40、 the document, shall be free from any magnetic ink other than CMC 7 character (see Figure 1). Under no circumstances may CMC 7 characters be printed within the clear band using non-magnetic ink.CMC 7 and E13 B fonts shall not be permitted in the same clear bank on any document. CMC 7 shall only appe
41、ar on the front of the document.Table 1 (continued)4 ISO 2013 All rights reservedBS ISO 1004-2:2013ISO 1004-2:2013(E)9 Character spacing and alignment9.1 Horizontal character spacing9.1.1 Character pitch, BThe distance between the orthogonal projections upon the bottom reference edge of the extreme
42、right mean edges (see 10.2.2) at mid-character height of adjacent characters. The nominal character pitch B may be as small as 3,17 mm . The horizontal spacing between characters shall be such that a minimum inter-character distance Dmis maintained.9.1.2 Intercharacter distance D between two adjacen
43、t charactersThe distance between the orthogonal projections upon the bottom reference edge of the right mean edges (see 10.2.2) at mid-character height of the left-hand stroke of the right-hand character and the right-hand stroke of the left-hand character.9.1.3 Minimum inter character distanceDm1=
44、0,67 mm if the right-hand character has one or two long intervals: and Dm2= 0,50 mm if the right-hand character has three long intervals.9.1.4 Character width AThe distance between the right mean edges of the outer most strokes of a character. The nominal values for characters with one, two and thre
45、e long intervals respectively, are as follows:A1= 2,0 mm A2= 2,2 mm A3= 2,4 mm 9.2 Vertical misalignmentVertical misalignment should be consistent with good printing practice and can be tolerated as far as the characters are completely contained in the printing band of the document. (See 7.2 and Fig
46、ure 1).10 Character definition and tolerances10.1 Definitions10.1.1 StrokeOne or more segments.10.1.2 Segment height, hThe distance between the top and bottom of that segment.10.1.3 Stroke height, MThe sum of the heights of the segments contained in that stroke.

48、 all strokes, each one being defined by two parallel lines having a fixed distance the printed edge zone width b from each other. The value of b is 0,06 mm.There are 14 printed edge zones in a character. Each printed edge zone extends over the full height of the stroke, excluding inter segment inter
49、ruptions and segment end zones.10.2.2 Mean edgeThe centre line of the printed edge zone dividing the irregularities of the printed edge, contained in the printed edge zone, in such a way that the sum of the non-inked areas on the stroke side is equal to the sum of the inked areas on the space side. If this sum is minimized, the centre line is then called theoretical mean edge.10.2.3 Theoretical mean edgeThe 14 theoretical mean edges of a character are used to determine the skew angle of the character (see 10.3); in this
