ABSTRACT:
The prevention of counterfeiting labels for various products is addressed by introducing counterfeit proof labels having optically concealed security safety features and clues for consumer's self identification and verification. The images of groups of questions and answers are printed in a precise serial formation, parallel to the optical center of the micro lenticule at the focal plane of a high resolution micro optic array of the label at the location in relation to the optical centers of the micro lenticule and viewing angle, so that each of the questions and answers can be read at a specific viewing angle. For identification, gently tilling the label back and forth, at different angles, each group of the question and answers will be displayed on the label. If the answers correctly match with the questions, the label is proved to be authentic; if one or more of the answers is wrong or not clear the label is a counterfeit. The label can be read under visible light source without any viewing aid.
