Identification of Wrinkled and Charred Counterfeit Currency Offset Printing Plate by Infrared Examination
Badly charred and burned material present unique and difficult identification problems for the document examiner. When these qualities are coupled with badly bent and wrinkled metal objects, the problems are compounded. This paper describes how a badly wrinkled and burned sheet of aluminum metal was identified as being a 20-dollar bill counterfeit money plate. The identification was made by use of an infrared viewer and infrared film.
