In order to satisfy present requirements and encourage the wide extension of OCR applications, two sets of characters are specified. 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 io range of applications. This i s also true for so-called sans serif ido, that is for a design which a t first sight has a thread-like appearance.
The resulting engraving is completely thread-like, 103-2 strokes having an equal width. 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.
The following sub-sets can be distinguished. Standards Subsctiption may be the perfect solution. Corners not specified as having a specific radius should be as sharp as practicable.

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 the purpose of this International Standard the following definitions apply: It is recommended t o use a tool the diameter of which is equal to the strokewidth.

The use of the original design is tolerated in numeric applications implemented before We are a non-profit group that run this website to share documents. Mechanisms using the constantstrokewidth font will usually maintain a fixed pitch. It comprises digits, capital letters, capital national letters and other graphics. The longest character is small letter j, because of i t s descender.
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.
They are also suitable for general purposes. 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.
The drawings are identified as follows: The use of the original design is tolerated in numeric applications implemented before October Report “ISO Subscription pricing is determined by: Ieo, it is not necessary for OCR purposes that the radii of the corners of the nominal printed image be less than 0,08mm 0.
