Paper Abstract

The use of electro-optics in sophisticated quality control systems has long been a standard in the machine tool and allied production industries. In the printing industry, however, apart fro, recent technological advances in optical character recognition, page scanners, and print character generators, little has been done in the field of printing quality control. This paper describes the relationship of electro-optical scanner systems for quality control in printing instruments of value (e.g. bank notes, Travelers Cheques etc.) and the subjective techniques currently employed by printers to evaluate such documents. Involved in this study is the application of image analysis, including spatial frequencies, authenticity verification, and processing techniques for the design of high speed quality control document processing systems.
