Introduction: Postage stamps are a form of security paper, similar to currency. Postage stamps prepay the government for a service - the delivery of the mail. Any counterfeiting or reuse of postage stamps defrauds the government of revenue for services rendered. Consequently, the United States government designs and produces its postage stamps under tightly controlled conditions using printing and design features intended to thwart counterfeiters. While security features designed to prevent reuse of a postage stamp help achieve anti-counterfeiting goals, anti-counterfeiting features do not necessarily prevent reuse.

Microprinting: Microprinting is the use of tiny printed letters, numbers and symbols on currency postage stamps and other security paper. Generally, the text cannot be seen with the naked eye, but becomes visible under magnification. The United States Postal Service (USPS) introduced microprinting in 1992 with the American Wildflower Series (an example seen above), the first U.S. commemorative stamp issue to be produced wholly by offset lithography. Over time, USPS refined its use of microprinting to introduce dates, words, abbreviations such as "USPS" and even entire stamp designs composed of microprinted letters.
