Abstract

A method of consistency, characterized by: selecting or manufacturing a batch of base materials, printing graphs, characters and microscopic points or lines on the base materials to form characteristic patterns, selecting one or more characteristic patterns as reference characteristic patterns, recording information of points, lines, graphs and characters in the reference characteristic patterns, position relations among the points, lines, graphs and characters, position relations (all included or partially overlapped), shapes of overlapped areas and colors formed after overlapping, and storing the information as characteristic information in a storage medium; when a certain base material pattern (to-be-evaluated pattern for short) is required to be identified to be consistent with the reference characteristic pattern, comparing the characteristic information of the reference characteristic pattern with the characteristic information of the to-be-evaluated pattern, if the compared similarity degree is greater than the set similarity degree, judging that the pattern on the certain base material is consistent with the reference characteristic pattern, otherwise, judging that the pattern on the certain base material is inconsistent with the reference characteristic pattern. The advantages are that: the recorded characteristic pattern characteristic information has little information, so that the workload of background service and management is greatly reduced.

Description

Consistency method

Technical Field

The invention relates to a method for the consistency of characteristic patterns of a base material, which is mainly used in the field of anti-counterfeiting.

Background art:

counterfeit products are the second largest public nuisance in the world, in addition to drugs. In order to combat counterfeiting, various anti-counterfeiting technical products are developed in countries around the world. The texture or similar texture anti-counterfeiting product is effective, the technical core of texture anti-counterfeiting is that each product produced by enterprises has natural random and uncopyable 'orientation' or 'fingerprint', the original same product is changed into a personalized product with a unique number and a unique uncopyable special certificate, the uncopyable characteristic of each product is photographed and filed, and the authenticity is identified by comparing whether the real object is consistent with the filed characteristic. Although the anti-counterfeiting effect is good, texture or texture-like photos need to be recorded in the background, so that background data is huge, management and storage are complex, and recovery of the system after problems occur is difficult. If the pattern is printed by a human or machine, the microscopic C, M, Y, K printed screen dots, lines, text, graphics, etc. will be very different in their relative positions even though the macroscopic appearance is consistent with the previous batch. Therefore, after the batch of characteristic patterns are printed, the microcosmically imitating the batch of characteristic patterns cannot be realized; by using the principle, one or more characteristic patterns with consistent microscopic characteristic information of a batch of recorded microscopic characteristic information can represent the batch of patterns, the patterns are stored in a storage medium, if a printed matter (to-be-evaluated printed matter) is judged to be a printed matter of a previous batch, whether the microscopic characteristic information of the to-be-evaluated printed matter is consistent with the microscopic characteristic information stored in the storage medium or not is mainly compared, if the microscopic characteristic information of the to-be-evaluated printed matter is consistent with the microscopic characteristic information, the same batch is obtained, and if the microscopic characteristic information is not consistent with the microscopic characteristic information, the same. If the same batch is on a genuine product, the product of that batch is not a counterfeit product.

The technical scheme adopted by the invention is as follows:

selecting or manufacturing a batch of base materials, printing graphs, characters and microscopic points or lines on the base materials to form characteristic patterns, selecting one or more characteristic patterns as reference characteristic patterns, recording information of points, lines, graphs and characters in the reference characteristic patterns, position relations among the points, lines, graphs and characters, position relations (all included or partially overlapped), shapes of overlapped areas and colors formed after overlapping, and storing the information as characteristic information in a storage medium; when a certain base material pattern (to-be-evaluated pattern for short) is required to be identified to be consistent with the reference characteristic pattern, comparing the characteristic information of the reference characteristic pattern with the characteristic information of the to-be-evaluated pattern, if the compared similarity degree is greater than the set similarity degree, judging that the pattern on the certain base material is consistent with the reference characteristic pattern, otherwise, judging that the pattern on the certain base material is inconsistent with the reference characteristic pattern.

The base material comprises paper, cloth and plastic.

The dots, lines, and patterns forming the characteristic pattern include a printed screen.

The characteristic information of the characteristic pattern comprises colors formed by overlapping points, lines, figures and characters of different layers.

The characteristic information of the characteristic pattern comprises relative positions of points, lines, figures and characters of different layers.

The colors of the dots, lines, and graphics of the characteristic pattern include colors awarded by an external factor.

The external factor reward includes ultraviolet irradiation, heating, and dripping.

Whether the pattern on a certain substrate (referred to as a pattern to be evaluated for short) is consistent with the reference characteristic pattern or not includes whether the local characteristic information of the pattern on the certain substrate (referred to as a pattern to be evaluated for short) is consistent with the local characteristic information of the reference characteristic pattern or not.

The invention has the following advantages:

the background records little characteristic patterns or characteristic information for comparison, so the workload of the background is greatly reduced.

FIG. 2___ is a schematic diagram of a pattern for printing FM screen with blue ink;

FIG. 3___ green ink printed triangle pattern schematic;

FIG. 4___ is a schematic view of a green ink printed text pattern;

FIG. 5___ shows a composite pattern on the same area of a substrate;

the specific implementation scheme is as follows:

Example 1

Selecting a batch of coated paper as a base material, and printing an AM screen pattern in the same area by using red ink, as shown in figure 1; printing FM method screen pattern with blue ink, as shown in FIG. 2; printing triangles with green ink, as in fig. 3, printing text with green ink, as in fig. 4, and magenta printed micro-lines, as in fig. 5, 9, results in a composite pattern on the same area of the substrate, which we do not refer to as a lot a, as in fig. 5. Selecting one or more recorded microscopic characteristic patterns as reference characteristic patterns, recording the information of points, lines, figures and characters of the reference characteristic patterns, the position relationship among the points, lines, figures and characters, the mutual position relationship after overlapping (all including or partially overlapping), the shape of an overlapping area and the color formed after overlapping, and storing the information as characteristic information in a storage medium; for example, the 1-dot red ink in fig. 5 is completely overlapped with the green printing triangle ink to form another color; the 2 dots in fig. 5 are superimposed with the green printed triangle portion to synthesize another color; in FIG. 5, 3 is the area and color of the green printing triangle green ink, red ink dots and blue ink dots; at 4 in FIG. 5 is a blank white area within the green printed triangle, where the positions of the red ink dots and the blue ink dots are located; at 5 in FIG. 5, the red ink dot overlaps the blue ink dot and includes the overlapping position, overlapping color and size; the 6 position in FIG. 5 is the blank area of the character "word", in which the positions of the red ink dots and the blue ink dots are located; the 7-dot red ink in FIG. 5 is completely overlapped with the green text "word" ink to synthesize another color; the 8-point red ink dots, the blue ink dots and the character 'word' ink in the figure 5 are overlapped to synthesize the colors and the relative positions; the microscopic straight lines of the 9 magenta ink in FIG. 5 correspond to the positions, overlaps, and colors after overlapping of the dots of red ink and the dots of blue ink; the above-mentioned red and blue ink dots, microscopic straight lines, triangles, relative positions between characters, shapes of overlapping regions, colors of overlapping regions, and the like constitute characteristic information of the reference characteristic pattern. The characteristic pattern or characteristic information is saved in a storage medium as a reference. When a person wants to judge whether the pattern of his printed matter is A batch of patterns, the microscopic pattern of his printed matter pattern is obtained by photographing or scanning, and compared with the reference characteristic pattern, if the similarity degree is greater than a certain set degree, such as 80%, the pattern of his printed matter is judged to be consistent with the reference characteristic pattern, otherwise, the pattern of his printed matter is inconsistent.

The invention is not limited to the specific embodiments described, but many variations can be made by a person having basic knowledge in the field to which the invention pertains, without departing from the inventive concept as claimed in the scope of the claims, which are intended to be covered thereby.
