Abstract
The United States Bureau of Engraving and Printing (BEP) is tasked with the function of producing billions of banknotes each year to be used by the general public throughout the world. Individual notes must maintain uniform consistency for both security features and print quality. The quality control process necessary to assure the uniform nature of United States currency requires a significant multi-tiered approach. Based on innovative opto-electronic techniques, individual security features are examined as a critical element during each phase of the production process. Print quality standards must also be strictly maintained and monitored to assure the uniformity of the most popular printed item in the world. This presentation describes the approach and some of the techniques developed and implemented within the BEP to carry out the necessary monitoring and control of the quality of intaglio currency printing plates.
