Dimensions of OCR-B are given in three sizes. The size III character centreline is defined by x3 and y 3. It can be used as a font with constant-strokewidth as well as a letterpress font. The whole character set 10733-2 looks less mechanical and bears more resemblance to the typographic forms t o which the human eye has been accustomed for centuries. Subscription pricing is determined by: Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.
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. One of the essential principles prescribes that in a letter design all vertical parts must be heavier than the horizontal parts. Your Alert Profile lists the documents that will be monitored.
Mechanisms using the constantstrokewidth font will usually maintain a fixed pitch. We need your help!
