Inspecting Money: How to Avoid Negative Bucks.

Abstract

The focus of the activity of the Inspection Laboratory in the past several years has been high-speed inspection of patterned surfaces. The Bureau of Engraving prints money on a high-speed web, which means that large sheets of money are being produced very fast. The question is raised of how to inspect for the print quality at those speeds. People will see either a blur or only a sample of the print. In this report, we use our past experiences to attempt to detail the inspection methods, hardware, etcetera, which would be needed to construct a hypothetical Inspect-a-buck system, and the problems that might be encountered along the way. Keywords: Scan resolution; Colors; Windows.
