ABSTRACT:
A black and white microfilm reproduction is made of a person or their photograph and accompanying text data. A sheet of multicolor photographic paper then is exposed to the black and white image carried on the microfilm and to another color film carrying a multicolor security pattern, mark or the like. The paper then is developed to produce the document having a black and white image of the person to be identified and accompanying text data together with overlying multicolor security pattern. The security pattern has lines that vary in color along their lengths independently of one another.
