Abstract

There has been a recent increase in the use and availability of full-color copiers. With this increase comes a greater potential for criminal use. Research by the authors has shown that many products of full-color copiers can be differentiated by the use of microscopy, infrared luminescence, infrared reflectance, and laser luminescence.
