Automated Visual Inspection Systems Help Ensure Quality and Security of U.S. Currency

Jan. 8, 2010
The Bureau of Engraving & Printing identified several areas of the bank note printing and production process that would benefit from automated visual inspection. To help ensure security, reduce variability and maintain BEP’s high print standards on each note, the BEP selected Sherlock machine vision software by DALSA.

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 sheer output of approximately 37 million notes each day, nearly every aspect of BEP’s design and printing process is distinctive. Many of the BEP’s quality assurance needs are unique as well. Like all printers, the BEP must verify that its printed materials are clear and accurate. However, the BEP also needs to ensure that various security measures are in place to help deter counterfeiting and to allow the government to account for all bank notes. 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.
