Abstract:
A method of manufacturing an inkless fingerprint composition and disposable applicator therefore comprising:a) providing a first and second substantially nonpermeable foil strips, the strips have substantially the same width with the first strip being slightly longer than the second strip to provide an extended pull-tab when the strips are superimposed on one another; b) providing an inkless fingerprint composition which is semisolid at ambient temperature, the composition including a color former which when applied to a person's fingerprint area and deposited onto a proper substrate in the presence of a developer forms a permanent colorant product representing the person's fingerprint; c) evenly distributing a thin layer of the composition on a surface of one of the strips while leaving a border around the perimeter of the strip without the composition; and d) placing the other strip over said one strip so that the composition is sandwiched between the strips with a peripheral border of both strips and the peel tab area being unencumbered with the composition.
