Description

Magic particle feature identification big label

Technical Field

The utility model belongs to the technical field of the false proof mark, concretely relates to big labeling of evil spirit grain feature recognition.

Background

Along with the progress of science and technology, the anti-counterfeiting means is more advanced and more diversified. In order to prevent the products of each commodity manufacturer from being counterfeited, the commodity manufacturers mostly adopt anti-counterfeiting marks to prevent the commodities produced by the manufacturers from being counterfeited.

The texture anti-counterfeiting technology is an anti-counterfeiting technology taking inherent texture characteristics of materials as anti-counterfeiting identification marks, and the important characteristic that texture distribution characteristic patterns are used for anti-counterfeiting identification marks is that each pattern is different, and the basic principle is as follows: randomly forming a texture distribution characteristic pattern, storing the texture distribution characteristic pattern into a cloud database for checking, calling out the contrast of the texture distribution characteristic pattern in the cloud database during identification, and judging whether the texture distribution characteristic pattern is false.

The anti-counterfeiting technical principle of the texture has been disclosed for many years, most of related products in the current market are texture paper products, namely, colored fibers are added into paper pulp to cause texture which can be seen by naked eyes, and then the texture is printed into the anti-counterfeiting mark, but the texture anti-counterfeiting mark has the problems of unobvious texture, poor touch and easy printing and imitation due to tiny texture particles forming the texture, and the anti-counterfeiting mark with obvious texture and good touch has large processing difficulty. For large labels of bottle bodies such as engine oil tanks and cosmetics, the attractiveness of the marks is influenced by full-page physical characteristics, the use amount of random physical characteristic particles is large, more materials are consumed, the cost is increased, in addition, the processing efficiency is low, the coating printing and information acquisition efficiency is low, and the yield is low.

Chinese patent CN 202010217263.3 discloses a random physical characteristic identification big label and a preparation method thereof, wherein the label comprises a first printing layer, a first plastic film layer, a first glue layer, a random physical characteristic layer, a second printing layer, a second plastic film layer, a color ink layer and a second glue layer, which are sequentially arranged from top to bottom. The random physical characteristic layer is formed by coating on the second printing layer, and the following problems exist in the coating process:

1) because the particles have a certain thickness, when the glue amount combined with random physical characteristics is small, scratches are easily generated on the printing layer and the second plastic film layer in the coating process, the surface effect of the mark is influenced, and the information reading of the printing layer is interfered seriously; when the glue water volume that combines with random physical characteristic is bigger, the coating is more smooth, is difficult to appear the mar, but when receiving extrusion or cross cutting, takes place to overflow easily and glues, the anti-phenomenon of gluing of sign appears in the production and processing process.

2) When coating the granule, the granule mixes in glue, because granule and glue density inconsistent, sinks easily or the come-up in the coating process, often appears coating inhomogeneous when leading to the coating, appears not having physical characteristic granule or the granule too much causes quality problems such as mar. This problem is solved to the mode that adopts manual stirring mostly at present, but direct coating occasionally certain effect after the manual stirring, but after coating a period, this problem reappears again, can not fundamentally solve this problem.
