21、ng Magnetic ink character recognition Part 1: Print specifications for E13B1 ScopeThis part of ISO 1004 specifies the shape, dimensions, magnetic signal level, and tolerances for the E-13B characters which include 10 numerals and four special symbols printed in magnetic ink and used for the purpose
22、of character recognition. It describes the various known types of printing defects and other printing considerations, together with the tolerances permitted.2 Character configuration2.1 DesignationThe series of standard magnetic ink characters shall consist of 10 numerals and four special symbols.

24、1004-1:2013(E)2.2 DimensionsDetailed dimensions and the reference centre-lines of the printed characters for the 10 numerals and four special symbols shall be as shown in Figure 1 to Figure 14.Figure 15 illustrates the character design matrix. All radii are 0,165 mm except in the character zero. All
25、 radii shall be blended with adjacent edges. Tolerance of each average edge = 0,038 mm. The minimum horizontal bars width is 0,279 mm. This minimum dimension does not apply to vertical bars (see 5.5).3 Character spacing and alignment3.1 Spacing3.1.1 Character spacingThe distance between the right av
26、erage edges of adjacent characters shall be 3,175 mm 0,254 mm. See Figure 16. Average edge is discussed in 5.2.3.1.2 Tolerance accumulationThe accumulation of spacing tolerances in any common field shall be limited to the extent that the accumulation does not infringe upon the boundaries defining th
27、is field.3.1.3 Special casesNormally a spacing of 6,35 mm 0,508 mm is accumulated when two characters within a field are separated by one space.Additional spacing tolerance of 1,5588 mm shall apply within a field or from field to field when printing does not guarantee to meet adjacent character spac
28、ing but only when surrounding spaces are utilized as a safety band. For those instances where a full space is not used, adjacent character spacing shall never be less than 2,921 mm or more than 4,064 mm.3.2 Alignment3.2.1 Reference pointAlignment is the relative vertical location of a character with
29、 respect to adjacent characters within a given field. The horizontal centre-line of each character is shown in Figure 1 through Figure 14. These centre-lines serve to establish vertical alignment of all characters, since all characters are designed about the same horizontal centre-line.3.2.2 Toleran
30、ceAlignment of a line of characters printed in any field shall be such that the bottom edges of adjacent characters within each field do not vary vertically by more than 0,762 mm (see Figure 17). These tolerances shall not accumulate so that the field exceeds the 6,35 mm encoding strip.On the symbol
31、s that do not come down to the “base-line” (On-Us and Dash, Figure 13 and Figure 14), the same 0,762 mm tolerance shall apply to the horizontal centre-line.4 Character skewThe maximum allowable character skew shall be 1,5 measured with respect to the aligning (bottom) edge of the document. See Figur
32、e 18.2 ISO 2013 All rights reservedBS ISO 1004-1:2013ISO 1004-1:2013(E)5 Character tolerances5.1 DimensionsSee Figures 1 to 14 for dimensions of the printed characters, and subclause 2.2.5.2 Average edge definitionThe typical edge of a printed character is not a straight line. The term “average edge
33、” shall be used for horizontal and vertical edges and is defined as an imaginary line, parallel to either the vertical centre-line or the horizontal centre-line that divides the irregularities. The result is that the summation of the white areas on one side of the line is equal to the summation of t
34、he black areas on the other side. The average edge of the radii shall be tangent to the average edge of the stroke. See Figure 19.5.3 Average edge toleranceThe average edge tolerance for all stroke edges shall be 0,038 mm applied to the dimensions (measured from the vertical centre-line and horizont
35、al centre-line) that locate the edges. A typical illustration of this tolerance is shown at the top of Figure 20. The average edge of the radii shall be tangent to the average edges of the character, and the tolerance of the radii shall also be 0,038 mm.5.4 Edge irregularity tolerance5.4.1 Average e
36、dge irregularitiesPeaks and valleys located about the average edge shall be permitted to extend to 0,089 mm from the average edge. An example is shown in Figure 20. However, when these occur, the summation of the edge present in the 0,038 to 0,089 mm zone shall not exceed 25 % of the total edge.5.4.
37、2 Edge voidsAn occasional void can be present at the edge of a character stroke and creates a valley that exceeds the 0,089 mm limit mentioned in 5.4.1. See Figure 20.No two voids as described shall occur within 0,889 mm of each other as measured from the points of maximum excursion from the average
38、 edge.Valleys that exceed the 0,089 mm zone are voids and are controlled by the void limits given in Clause 6 and shall be measured from the average edge of a character stroke. However, any portion of an edge void that is within the 0,089 mm zone shall be included in the measurement of the percentag
39、e of the edge present in the 0,038 to 0,089 mm zone.Figures 1 to 14 show dimensions for printed characters, in accordance with the following requirements. All radii shall be 0,165 mm except in character zero. All radii shall be blended with adjacent edges. Tolerance (average edge) = 0,038 mm Minimum
40、 horizontal bars width shall be 0,279 mm. This does not apply to vertical bars (see 5.5). All dimensions on figures below are in millimetres.

Such occasional excursions shall not be considered as edge irregularities and are defined as extraneous i

These occasional 12 ISO 2013 All rights reservedBS ISO 1004-1:2013ISO 1004-1:2013(E)excursions are allowed if each can be contained in a 0,076 mm 0,076 mm square. Those excursions that cannot be contained in a 0,076 mm 0,076 mm square are acceptable, provided
46、that they can be contained in a 0,102 mm 0,102 mm square and shall be limited to one per character and shall total not more than five per field.In measuring the size of such excursions, only that portion extending beyond the 0,089 mm limit shall be considered since the portion of the excursion withi
47、n the 0,038 mm to 0,089 mm zone is controlled by character edge irregularity limits given in 5.4.5.6 Minimum width of horizontal barsThe distance between the average edges of any horizontal bar shall be at least 0,279 mm. This specification is an adjunct to the dimension specification locating each
48、edge. This specification does not apply to vertical bars, since vertical bars are controlled entirely by dimensions locating each edge.6 Voids6.1 Maximum allowable single voids6.1.1 VoidsThe maximum allowable single void (the absence of ink within the specified outline of the printed character) anyw
