Sawtooth micropore anti-counterfeiting method and printed matter

Abstract

The invention belongs to the technical field of information query type anti-counterfeiting, and particularly relates to a sawtooth micropore anti-counterfeiting method and a printed matter. The methodcomprises the steps of presetting a plurality of artificial micropores on the two-dimensional code or / and the image-text; after the artificial micropores naturally shrink and become sawtooth micropores in random shapes, drying and curing the printing ink; amplifying the shot sawtooth micropores, and storing the shot microscopic characteristic information into an anti-counterfeiting inspection system database accessed to the Internet to serve as an anti-counterfeiting characteristic information file. The method is easy to produce and manufacture, and the authenticity of the low-end smart phonewith the rear lens resolution larger than 5 million pixels can be recognized conveniently.

Description

technical field

[0001] The invention belongs to the field of information query anti-counterfeiting technology, and specifically relates to an improved application technology of the Chinese invention patent "Sawtooth Anti-counterfeiting Method for Mobile Phone Identification Code (CN104794629B)". Background technique

[0002] Paragraphs

[0019] and

[0022] of the Chinese Invention Patent "Sawtooth Anti-Counterfeiting Method for Mobile Phone Identification Code (CN104794629B)" filed by the applicant on May 15, 2015, require "lens resolution ≥ 8 million pixels" High-end smartphones can identify large sawtooth with a size range of "0.3mm(H)×0.3mm(W)~0.05mm(H)×0.05mm(W)". During the implementation of its patent, it encountered the following two application technical problems.

[0003] First, small sawtooth, which cannot be recognized by low-end smartphones. Under normal printing production conditions, the sawtooth grown by ink infiltration has an average size of only 0.03mm(H)×0....
