Embodiment 1

[0058] produce a figure 1 Print shown (1).

[0059] At least one unique code (2) is spray-printed for each printed matter (1).

[0060] The first step is to generate a batch of unique coding (2) electronic image files in the computer in advance, and preset some 0.15mm wide square artificial microholes (7) on the coding (2) electronic images, see Figure 8 .

[0061] The second step is to use a liquid ink with a surface tension of Y, such as UV inkjet ink, to print the code (2) of the artificial micropore (7) preset with a square onto the printed matter (1) whose surface energy is C On the surface, where C>Y; for example, pre-print a partially wet coating with a surface energy C greater than 48 dynes / cm, and then use a liquid ink with a surface tension Y less than 24 dynes / cm to code (2) or / and graphics (3) are printed on the partial wetting coating; all in all, the selected liquid ink can infiltrate the selected printing surface, that is, the greater the difference betwe...

Embodiment 2

[0067] produce a figure 2 Print shown (1).

[0068] Each printed matter (1) is spray-printed with at least one unique code (2) and graphic (3).

[0069]The first step is to generate a batch of unique codes (2) and text (3) in the computer in advance, and preset some artificial micropores (7) with a diameter of 0.05mm on the electronic image of the text (3) , see Image 6 .

[0070] The second step is to select a liquid ink with a surface tension of Y, spray-print the code (2) onto the printed matter (1), and spray-print the graphic (3) preset with artificial micropores (7) onto a surface energy of C on the printing surface, where Y>C; for example, pre-print a partial non-wetting coating with a surface energy C greater than 28 dyne / cm, and then use a liquid ink with a surface tension Y less than 48 dyne / cm to print the graphic (3) Spray printing on the partial non-wetting coating; in a word, the selected liquid ink can not infiltrate the selected printing surface, that is,...

Embodiment 3

[0078] produce a Figure 5 Print shown (1).

[0079] At least one unique code (2) is spray-printed for each printed matter (1).

[0080] The first step is to generate a batch of unique codes (2) in the computer in advance, and preset some artificial micropores ( 7).

[0081] The second step is to use liquid ink with a surface tension of Y, and print the code (2) onto the printing surface with a surface energy of C, where C>Y; for example, pre-print a surface energy C greater than 38 dyne / centimeters of partially wetted coating, and then spray-print the code (2) onto the partially wetted coating with a liquid ink having a surface tension Y of less than 28 dynes / cm; in general, the greater the difference between C and Y, the better, but C and Y It should not be equal or close; only in this way can the artificial micropores (7) surrounded by the liquid ink shrink naturally and randomly deform under the action of the infiltration force, so that the artificial micropores (7) pr...

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....
