Abstract
A counterfeit resistant label for goods is manufactured by selecting a code word from a plurality of possible code words to identify a particular label and desired information relative to the goods with which the label is to be associated, applying the code word as a series of marks in several but less than all of a plurality of predetermined locations on the face of the label using an ink that is sensitive to light in the nonvisible spectrum, and masking the visibility of the ink in light in the visible spectrum over substantially all of the predetermined locations.
