Abstract

We design and analyze a high-speed document sensing and misprint detection system for real-time monitoring of printed pages. We implemented and characterized a prototype system, comprising a solid-state line sensor and a high-quality imaging lens, that measures in real time the light reflected from a printed page. We use sensor simulation software and signal processing methods to create an expected sensor response given the page that is being printed. The measured response is compared with the predicted response based on a system simulation. A computational misprint detection system measures differences between the expected and measured responses, continuously evaluating the likelihood of a misprint. We describe several algorithms to identify rapidly any significant deviations between the expected and actual sensor response. The parameters of the system are determined by a cost-benefit analysis.
