Case Study: Vision Inspection Ensures Currency Quality
The U.S. Department of the Treasury's Bureau of Engraving and Printing is responsible for producing all of the currency for the world's largest economy.
The U.S. Department of the Treasury's Bureau of Engraving and Printing (BEP) is responsible for producing all of the currency for the world's largest economy. From the paper on which the currency is printed, to its output of about 37 million notes each day, most aspects of BEP's design and printing processes are distinctive. Many of its quality assurance needs are unique as well. The agency verifies that its printed materials are clear and accurate and meet all security requirements. To help meet these demanding requirements, the BEP converted several of its inspection stations from human operators spot checking currency to automated visual inspection of each note.
