Abstract
The invention relates to a near-infrared absorbing ink and near-infrared non-absorbing ink combined anti-counterfeiting method. The near-infrared absorbing ink is formed by processing a near-infrared absorbing material and an ink connecting material; and the near-infrared non-absorbing ink is formed by processing a near-infrared non-absorbing material and the ink connecting material. According to the combined anti-counterfeiting method, the near-infrared absorbing ink is printed on a substrate; the near-infrared non-absorbing ink locally or completely covers patterns printed by using the near-infrared absorbing ink so as to hidden patterns printed by the near-infrared absorbing ink; according to near-infrared identification equipment, infrared light beams matched with the near-infrared absorbing ink are used to irradiate and photograph the patterns; after an infrared light source lightens patterns to be identified, specific near-infrared light is reflected by the patterns printed by the near-infrared absorbing ink, pattern information is amplified by a lens module and is filtered by a filtering lens; a coding image is acquired by using a pattern sensor; and the coding image is converted into corresponding digital information by using a signal processor in the near-infrared identification equipment and the image is identified to be true or not.
Description
Technical field
