Description

Technical Field

[0001] The invention relates to the technical field of anti-counterfeiting labels, and in particular to a method for making a dot matrix code label based on a photosensitive material and an application thereof. Background Art

[0002] Anti-counterfeiting labels are labels that can be pasted, printed, or transferred on the surface of the subject matter, or on the packaging of the subject matter, or on the accessories of the subject matter, and have an anti-counterfeiting effect. Consumables refer to accessories that are frequently consumed. There are many types of consumables. The traditional way to identify the expiration date of consumables is to observe the expiration date on the packaging. This method greatly increases the manpower and time spent by staff in identifying the expiration date of consumables.

[0003] Existing consumables such as air filters and water filters are mostly controlled by radio frequency identification (RFID), which is very expensive. In addition, RFID tags are not copy-proof and easy to crack, and cannot solve the problem of preventing the reuse of devices in a non-networked state. Therefore, we propose a method for making a dot code tag based on photosensitive materials and its application to solve the above problems.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field. Summary of the invention

[0005] The purpose of the present invention is to provide a method for producing a dot matrix code label based on a photosensitive material and its application, so as to solve the problems raised by the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a dot code label based on a photosensitive material, the dot code label comprising a label layer, the label layer having a dot code printed on one side thereof covered with a photosensitive layer, the photosensitive layer being covered with a light-shielding layer, the light-shielding layer being provided with a glue coating on one side thereof which is bonded to the photosensitive layer, the photosensitive layer being made of a photochromic material and a film-forming material, and the light-shielding layer being made of an aluminum-laminated film.

[0007] The present invention also provides a method for making a dot matrix code label based on a photosensitive material, comprising the following steps:

[0008] S1. Make dot code labels: print digital dot codes on label paper;

[0009] S2. Making a photosensitive film: mixing a photochromic material into a film-forming material, making a uniform film under light-proof conditions, and covering both sides with an aluminum-laminated film with a glue coating for light shielding;

[0010] S3, Lamination: Under light-proof conditions, remove one side of the photosensitive film and laminate the aluminum film, then cover it on the side of the label paper with the dot matrix code printed on it.

[0011] Preferably, in said S1, the dot matrix code is a plain code or a coded code.

[0012] Preferably, in S2, the photochromic material includes but is not limited to photosensitive silver salts, diazonium salt compounds, spiropyran derivatives, and photosensitive polymers.

[0013] Preferably, in S2, the film-forming material includes but is not limited to PET, PVC, and PP.

[0014] The present invention also provides an application of a dot code label based on a photosensitive material as described above in a consumables authorization control label.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention uses a photosensitive material to make a photosensitive film and covers it on the label paper. When the photosensitive material is exposed, the consumables marked with the attached label have been loaded and used, and the label cannot be used again, thereby solving the problem of anti-reuse of equipment in a non-networked state.
