alphanumeric photocomposition system
Quick Summary
The term "alphanumeric photocomposition system" refers to a highly advanced form of computerized typesetting. These systems generate characters electronically and transfer them to film or light-sensitive paper using lasers or cathode-ray tubes. Unlike earlier mechanical phototypesetters, electronic systems eliminate most moving parts, significantly increasing speed and efficiency.123
These systems store character designs in digital memory, allowing for rapid selection and projection onto a screen. This enables incredibly high production rates, with some systems capable of setting thousands of characters per second. This technology revolutionized the printing industry by offering unprecedented speed and cost-effectiveness compared to traditional metal typesetting.231

printingThird generation of phototypesetters: electronicPhototypesetters of this kind (called alphanumerical) have theoretical performance rates exceeding 3,000 characters per second, or more than 10,000,000 per hour, and should be able to approach 30,000,000. Speeds such as these exceed the production rate even of magnetic tape. Consequently, to work at its most efficient output, such a…
