Abstract:
Improved product labels cannot be easily counterfeited. A plurality of small dots printed on the label are interpreted as dirt or flaw or misprint so that the counterfeit label will not reproduce the plurality of small dots. A first image printed on the label and having a first level of spectural reflectivity, and a second image printed atop the first image using ink having a spectural reflectivity different from the spectural reflectivity of the first image. A plurality of very small dots creates a grayscale field, and a symbol printed within the grayscale field of very small dots, thereby creating a watermark of such high complexity that it cannot be counterfeited. A symbol printed on the label, and a raised dot of ink printed atop the symbol at a precise location to be sensed by finger contact and thereby indicate the authenticity of the label.
