FOREWORD
I S 0 (the International Organization for Standardization) is a worldwide federation of national standards institutes (IS0 Member Bodies). The work of developing International Standards is carried out through IS0 Technical Committees. Every Member Body interested in a subject for which a Technical Committee has been set up has the right to be represented on that Committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. Draft International Standards adopted by the Technical Committees are circulated to the Member Bodies for approval before their acceptance as International Standards by the IS0 Council. International Standard I S 0 1073/11 was drawn up by Technical Committee ISO/TC 97, Computers and information processing, and was circulated to the Member Bodies in May 1975.
It has been approved by the Member Bodies of the following countries :
--`,,```,,,,````-`-`,,`,,`,`,,`---
Australia Belgium Brazil Czechoslovakia Denmark France Germany
Hungary Italy Japan Netherlands New Zealand Romania South Africa, Rep. of
Sweden Switzerland Turkey United Kingdom Yugoslavia
The Member Body of the following country expressed disapproval of the document on technical grounds : U.S.A. This International Standard, together with IS0 1073/1, cancels and replaces IS0 Recommendation R 1073-1969.

Alphanumeric character sets for optical recognition Part II : Character set OCR-B - Shapes and dimensions of the printed image
digits, capital and small letters, all the graphics specified in the IS0 7-bit coded character set ( I S 0 646-1973), national letters, diacritical signs and further graphics.
1 GENERAL 1.1 Scope This International Standard for character shapes and sizes is intended to facilitate and foster the use of Optical Character Recognition (OCR) in data processing, by defining character shapes suitable for both human and machine reading.
It establishes a common basis for printing equipment and optical scanning equipment for OCR interchange applications.
NOTES
1 For applications which involve circulation of documents across boundaries between areas in which different national characters are in use, agreement between the sender and the recipient of the documents is required. 2 The metric and inch dimensions in this International Standard are rounded and therefore consistent but not exactly equal. Either system may be used but the two should not be intermixed.
1.2 Field of application
2 STYLES
This International Standard specifies the printed image shapes and sizes of alphanumeric characters, graphics and symbols designed for use in Optical Character Recognition. They are also suitable for general purposes.
The OCR-B font (see clause 13) comprises 121 characters, but, in general, only a subset will be used for a specific application.
In order to satisfy present requirements and encourage the wide extension of OCR applications, two sets of characters are specified. These are named OCR-A and OCR-B. Character s e t OCR-A includes the numeric sub-set which was recommended in draft IS0 Recommendation No. 890 (now part of this International Standard). The shapes of the characters have been designed to be suitable for use in many applications of OCR. Dimensions of OCR-A are given in three sizes. (See part i.) The shapes of the OCR-B characters have been designed for use in OCR systems without undue sacrifice of their suitability for general purposes in a wide range of applications. Dimensions of OCR-B are given in three sizes.
--`,,```,,,,````-`-`,,`,,`,`,,`---
Additional International Standards will cover the print quality and the relevant characteristics of the formats needed to satisfy interchange requirements.
3 I t is recognized that some type-making and printing processes will not be able to produce sharp corners. Corners not specified as having a specific radius should be as sharp as practicable. However, it is not necessary for OCR purposes that the radii of the corners of the nominal printed image be less than 0,08mm (0.0035 in).
The character shapes and dimensions are specified by reference drawings on a reference grid. The nominal strokewidth is constant for each character of the standard s e t entitled "constant-strokewidth font"; the centreline of each character i s indicated on the reference grid. A second style of characters entitled "letterpress font" may be used with printing equipment which can reproduce fine details with sufficient accuracy. For many classes of printers, however, the strokewidth is less controllable and therefore for these printers the constant-strokewidth font shall be used.
1.3 Definitions
For aesthetic reasons, the strokewidth of the letterpress font characters i s varied deliberately and the stroke endings are specially designed. But the centrelines are the same for both fonts and these centrelines, as defined for the constantstrokewidth font, are the definitive part of this standard.
For the purpose of this International Standard the following definitions apply :
3 OCR-BSIZES
1.3.1 OCR-A : A repertoire of 69 characters of which 56 are graphics included in the I S 0 7-bit coded character set ( I S 0 646-1973). It comprises digits, capital letters, capital national letters and other graphics. (See part i.) 1.3.2 OCR-B : A repertoire of 121 characters comprising
3.1 Three sizes are specified for OCR-B characters in order to provide for use with a wide range of printing equipment processing differing print quality characteristics. Devices such as typewriters, cash registers, numbering machines, high-speed printers, and credit card imprinters, besides printing processes such as letterpress and offset lithography, are all suitable.

3.7 The widest character in each size (except for the alternative small letter m) is digit Z E R O . I t s centreline widths are :
3.2 The letterpress font i s specified in size I (the smallest) only. It provides the option of a variable pitch between characters as i s usual with letterpress.
1,40mm (0.055in) 1,52 mm (0.060in) 2,lO mm (0.083in)
for size I :
3.3 The constant-strokewidth font is specified in three
for size III :
sizes, I, I I I and IV. Mechanisms using the constantstrokewidth font will usually maintain a fixed pitch.
for size IV :
3.8 Constant-pitch printing
3.4 Size II which was in ISO/R 1073-1969 has been deleted. (See annex B.)
In constant-pitch printing for OCR applications, the follow ing minimum nominal pitches are appropriate :
3.5 The centrelines for the three sizes are simply related by appropriate horizontal and vertical scale factors. The factors for size III and size IV referred to size I are :
size I :
2,54 mm (0.100in) min. 2,54mm (0.100in) min. 3,63mm (0.143in) min.
size I I I :
size I V :
for size III Vertical : 1,333
Horizontal : 1,086
for size IV Vertical : 1,500
4 TYPICAL DIMENSIONS OF THE NOMINAL PRINTED IMAGE
Horizontal : 1,500
This scale relationship does not apply t o the outline shapes, since nominal strokewidth i s not strictly proportional to centreline dimensions. The strokewidths for each size are shown in the reference drawings.
4.1 Constant-strokewidth font Typical dimensions for the nominal printed image of the constant-strokewidth font in size I are given below. These dimensions are the heights above and below the horizontal base line of digits, capital and small letters, ascenders and descenders (see figure 1). These dimensions are for general information only. The values for individual characters are obtainable from the reference drawings.
3.6 The character with the greatest height in each size is digit EIGHT. It is the character which extends farthest above the base line for capital letters. The longest character is small letter j, because of i t s descender. The centreline heights of the character E I G H T are : for size I : for size III :
The shapes of the letterpress characters are similar except that the stroke ends are not rounded. --`,,```,,,,````-`-`,,`,,`,`,,`---

ANNEX A
(not part of the standard)
OLD DESIGN OF DIGIT ZERO
The character Z E R O i s the only numeral which had to be modified in this revision of ISO/R 1073-1969. The use of the original design is tolerated in numeric applications implemented before October 1976. OCR reading of both old and revised design is subject to special agreement between OCR equipment supplier and user. For any application implemented after 1976, only the new design is standard. The following illustration shows the letterpress font and the constant-strokewidthfont of digit Z E R O in size I a t scale 30 : 1 and the centreline of the constant-strokewidthfont in size III also a t scale 30 : 1. Letterpress font The nominal printed image of the character is described by a series of points on the character outline, numbered from 101 onwards. Two additional reference points numbered 1 and 3 are provided together with a vertical reference line 2. Reference points 1 and 3 establish the vertical position, the orientation and the width. Reference line 2 establishes the horizontal position for printing pitch. All the points are described in a rectangular co-ordinate system. To avoid negative co-ordinates, the points 1 and 3 are given the positive vertical ordinate y = 2 O00 pm and the reference line 2 is given the positive abscissa x = 2 O00 pm. The size I character outline is defined by x1 and y , . Constant-strokewidthfont The nominal printed image of the character is defined by i t s centreline and by i t s nominal strokewidth 0,35 rnm for size I and 0,38 mm for size III. The character centreline is described by a series of points numbered from 11 onwards. The size I character centreline is defined by x1 and y l . The size III character centreline is defined by x3 and y 3 .

ANNEX B
(not part of the standard)
EXISTING APPLICATIONS USING FORMER SIZE II WITH FORMER FONT DESIGN OF THE TEN DIGITS
This annex i s not part of the standard; it is presented for information only. The previous version of this International Standard (ISO/R 1073-1969)included a size which has been removed from the present edition. However, some long-term numeric applications have in the meantime implemented the ten digits in size II and their existence must be recognized for a long period after the issue of this edition of the standard. Those applications, initiated before 1976,may be considered as standard, as far as they conform to the specification, charts and drawings given in the following pages. An application such as the printing of transferable securities (shares, bonds) implemented prior to 1976 i s entitled to continue even for new bonds issued after 1976. For any application implemented after 1976,only sizes I, III and I V with the new font design are standard. Use of co-ordinate tables and reference point drawings The nominal printed image of each character is defined by i t s centreline and by i t s nominal strokewidth. The character centreline i s described by a series of points numbered from 1 1 onwards. Two additional reference points numbered 1 and 3 are provided together with a vertical reference line 2. Reference points 1 and 3 establish the vertical position, the orientation and the set-width. Reference line 2 establishes the horizontal position for printing pitch. All the points are described in a rectangular Co-ordinate system. To avoid negative coordinates, the points l and 3 are given the positive ordinate y = 2 O00 pm and the reference line 2 is given the positive abscissa x = 2 O00 pm. Character centrelines are established for size II by x , and y 2 . The nominal strokewidth is 0,35 mm.

ANNEX C
(not part of the standard)
RECOMMENDATION FOR THE IMPLEMENTATION OF OCR-B ON TYPEWRITERS
The design of OCR-B is based on fundamental aesthetic laws which, as far as feasible, correspond to the criteria emerging from the long development of our classic typography. One of the essential principles prescribes that in a letter design all vertical parts must be heavier than the horizontal parts. This i s also true for so-called sans serif characters, that is for a design which a t first sight has a thread-like appearance. This is precisely the case for OCR-B. The OCR-B character setcan be implemented in twoclearlydifferent forms. It can be used as a font with constant-strokewidth as well as a letterpress font. Type engraving can be based on either implementation. For printing devices like high-speed printers and similar machines, the centreline is the skeleton along which a stroke of prescribed width i s placed. It is recommended t o use a tool the diameter of which is equal to the strokewidth. The resulting engraving is completely thread-like, all strokes having an equal width. The aesthetic appearance as well as readability are partly diminished by this process. I n spite of strong technical limitations and difficulties, there is a tendency t o design type fonts for typewriters which, as close as possible, look like letterpress fonts. For this type of application it is therefore strongly recommended to use a finer tool and to base the design on the OCR-B letterpress font used as basic pattern. Using a tool with a diameter equal to half the strokewidth, it should be possible to engrave types presenting most of the intended variations of the strokewidth. Furthermore, the ends of the strokes, instead of being rounded, would then have a more rectangular appearance. Also, the internal angles would remain more open. The whole character set then looks less mechanical and bears more resemblance to the typographic forms t o which the human eye has been accustomed for centuries. Each manufacturer is, of course, free to take advantage of the aesthetic features of the letterpress font, depending on the technical means a t his disposal and on his desire to achieve a more typographic appearance of the characters.
