The shapes of the characters have been designed to be suitable for use in many applications of OCR. If the document is revised or amended, you will be notified by email.

This is precisely the lso for OCR-B.

The following illustration shows the letterpress font and the constant-strokewidthfont of digit Z E R O in size I a t scale 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. The drawings are identified as follows: A repertoire of characters comprising 3. 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.

The values for individual characters are obtainable from the reference drawings. Character set OCR-B – 10733-2 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 0national letters, diacritical signs and further graphics. The longest character is small letter j, because of i t s descender.

It establishes a common basis for printing equipment and optical scanning equipment for OCR interchange applications. The OCR-B font see clause 13 comprises characters, but, in general, only a subset will be used for a specific application.

This standard is not included in any packages. Mechanisms using the constantstrokewidth font will usually maintain a fixed pitch. Initial alphanumeric sub-set This sub-set comprises 47 characters: For the purpose of this International Standard jso following definitions apply: The character centreline is described by a series of points numbered from 11 onwards.

Standards Subsctiption may be the perfect solution. NOTES 1 For applications which involve circulation of documents across iiso between areas in which different national characters are in use, agreement between the sender and the recipient of the documents is required.

It can be used as a font with constant-strokewidth as well as a letterpress font. Please first verify your email before subscribing to alerts. I n spite of strong technical isoo and difficulties, there is a tendency t o design type fonts for typewriters which, as close 10073-2 possible, look like letterpress fonts. 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.

It i s recommended that prospective users of this standard consult manufacturers before deciding on a particular character set. Two additional reference points numbered 1 and 3 kso provided together with a vertical reference line 2.

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. For many classes of printers, however, the strokewidth is less controllable and therefore for these printers the constant-strokewidth font shall be used.

For any application implemented afteronly the new design is standard. Dimensions of OCR-B are given in three sizes. Proceed to Checkout Continue Shopping. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. In constant-pitch printing for OCR applications, the follow ing minimum nominal pitches are appropriate: It provides the option of a variable pitch between characters as i s usual with letterpress. Reference line 2 establishes the horizontal position for printing pitch.

International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. 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.

These dimensions are for general information only. The use of the original design is tolerated in numeric applications implemented before Character centrelines are established for size II by xand y 2.

It has been approved by the Member Bodies of the following countries: We have no document history for this standard.
