The two-dimensional code has the characteristics of large information storage capacity, high confidentiality, high traceability, high damage resistance, easiness in realizing informatization management and the like, so that the two-dimensional code is widely applied to the fields of product traceability, anti-counterfeiting and the like. The existing product two-dimension code traceability system is generally provided with a product traceability information database, product traceability information related to a product is submitted to a product traceability platform, the product traceability platform stores the product traceability information in the database, and after a two-dimension code is generated according to a corresponding coding rule, a label is made and pasted on a product package and sent to a dealer for sale. The consumer can utilize the two-dimensional code installed on APP scanning product package on the intelligent terminal to obtain detailed product traceability information.

Detailed Description
In order to more clearly illustrate the technical solutions of the present invention, the present invention will be briefly described below by using embodiments, and it is obvious that the following description is only one embodiment of the present invention, and for those skilled in the art, other technical solutions can be obtained according to the embodiments without inventive labor, and also fall within the disclosure of the present invention.
The two-dimensional code label of the embodiment of the invention, referring to fig. 1, comprises a base layer 10, a time temperature indicator layer 20, a transparent film layer 30 and a masking layer 40 from bottom to top. The base layer 10 may be a transparent resin layer that can be attached to the outer package of the product. The time temperature indicator layer 20 is initially light in color and changes color to a dark color after the time above the critical temperature reaches the critical time. A polymerization type or enzyme type time temperature indicator material may be used as the time temperature indicator layer 20. The two-dimensional code image is printed on the transparent film layer 30 by ink. The masking layer 40 is made of a non-transparent material, is disposed on the transparent thin film layer 30, and has an edge slightly larger than the transparent thin film layer 30, so that the masking layer can be uncovered from the transparent thin film layer 30 to obtain a two-dimensional code image.
The two-dimensional code label represents the source and the current quality information of the product through the characteristic code information product contained in the two-dimensional code label. The feature code comprises a plurality of number segments, and each number segment comprises a unique feature identification number segment, a product source information number segment and a product quality information number segment. Each two-dimension code label is provided with a unique characteristic identification code number section corresponding to a unique commodity, the database identifies the unique characteristic identification code after the unique characteristic identification code is inquired in the database once, and when the product information of the unique characteristic identification code is inquired again, the inquiry of the two-dimension code is prompted.
The corresponding information of the product source information number section can comprise a product number, a product name, a product type, a product grade, a product origin, a product manufacturer, a product batch, a product production date, a product quality guarantee period and the like; and the information corresponding to the product quality information number segment indicates that the current quality of the product is abnormal or normal. Each two-dimension code label corresponds to information of a single product, corresponding information of the product is generated into a corresponding two-dimension code image according to two-dimension code coding after the product is produced, and the product can be coded by using the existing two-dimension code coding technology such as QR two-dimension codes. And storing the parameters of each number segment of the feature codes and the specific information corresponding to each parameter through a database.
The two-dimensional code label comprises a first two-dimensional code image and a second two-dimensional code image; the unique feature identification code number segment in the two-dimensional code information feature code corresponding to the first two-dimensional code image and the second two-dimensional code image is the same as the feature code of the product source information number segment, and the feature codes corresponding to the product quality information are different. Namely, two-dimension code images are set for the same product, and only the feature codes of the product quality information in the two-dimension code images are different. The current quality information of the product corresponding to the first two-dimensional code image is that the product quality is normal, and the current quality information of the product corresponding to the second two-dimensional code image is that the product quality is abnormal. When the first two-dimensional code image is printed, the two-dimensional code image according to the coding rule is generated according to the feature code of the first two-dimensional code image, the dark color code element is printed on the transparent film layer 30 by using low-temperature color-changing ink, and the color of the low-temperature color-changing ink is changed into dark color at the cold chain transportation temperature of the food. When the second two-dimensional code image is printed, the two-dimensional code image is generated according to the characteristic code, then the dark-color code element and the light-color code element in the two-dimensional code image are reversed to generate an inverse code image, and then the dark-color code element in the inverse code image is printed on the transparent film layer 30 by using light-color pigment.
In the production process of the two-dimensional code label, because the dark color code element in the first two-dimensional code image of the two-dimensional code label uses the low-temperature color-changing pigment, the color of the two-dimensional code label is changed only in the cold chain transportation process, and therefore the first two-dimensional code image cannot be copied in the production and printing process. For the second two-dimensional code image, since the time temperature indicator layer is light-colored, its difference in reflectance from the light-colored pigment-generated symbols in the second two-dimensional code image is insufficient, and cannot be recognized and thus cannot be reproduced.
In the process of cold chain storage and transportation of a product with a two-dimensional code label, a dark color code element in a first two-dimensional code image is changed into a dark color, if the cold chain temperature is normal all the time, the color of a time temperature indicator layer 20 in the two-dimensional code label is not changed, so that the dark color code element in the first two-dimensional code image and a light color background of the time temperature indicator layer 20 form enough reflectivity difference, and the first two-dimensional code image can be identified; whereas the light-colored symbols in the second two-dimensional code image are not recognizable as an image against the light-colored background of the time-temperature indicator layer 20. If the product is abnormally stored after the time exceeding the critical temperature reaches the critical time in the cold chain storage and transportation process, the color of the time temperature indicator layer 20 becomes dark, so that the difference between the reflectivity of the dark-color code element in the first two-dimensional code image and the reflectivity of the dark-color background of the time temperature indicator layer 20 is too small to be identified, and the two-dimensional code image formed by the light-color code element in the second two-dimensional code image and the dark-color background of the time temperature indicator layer 20 can be identified.
As another aspect of the present invention, referring to fig. 2, the two-dimensional code label printing method includes the following steps: (1) arranging a base layer, a time temperature indicator layer and a transparent film layer from bottom to top; (2) generating a first two-dimensional code image and a second two-dimensional code image according to the product information, wherein the first two-dimensional code image corresponds to normal product information, and the second two-dimensional code image corresponds to abnormal product information; (3) printing the dark color code element of the first two-dimensional code image on the transparent film layer by using low-temperature color-changing ink; (4) generating an anti-code image of the second two-dimensional code image; (5) printing the dark-color code elements of the code reversal image of the second two-dimensional code image on the transparent film layer by using light-color pigments; (6) a masking layer is disposed on the transparent thin film layer.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
