Description

Print-through double-layer recycling-prevention label

Technical Field

The invention belongs to the technical field of anti-recycling label printing, and particularly relates to a perspective printing double-layer anti-recycling adhesive sticker label.

Background

The double-layer recycling-preventing label such as a Chinese patent application ' uncovering type anti-counterfeiting mark and a preparation method thereof (CN 105469704B) ' a novel plastic film uncovering bottom-leaving label (CN 206711492U) ' comprises a label upper layer (called as an uncoverable surface layer in the application) and a label lower layer (called as a non-uncoverable bottom layer in the application); the lower layer of the label comprises a release agent layer, an opaque layer (referred to as a colored background layer in the application) and a non-setting adhesive layer, and the lower layer is printed with anti-counterfeiting information such as anti-counterfeiting pictures and texts. The production process sequence of the double-layer recycling-preventing label is as follows: firstly, anti-counterfeiting information is printed on a surface layer coiled material with the back surface pre-coated with a release agent in a printing factory, the printed surface layer coiled material is transported to a non-setting adhesive product factory to be coated with non-setting adhesive, and then the surface layer coiled material processed by the coating adhesive is transported to the printing factory to print the surface layer and complete post-processing procedures such as die cutting and the like. The disadvantages of this production process sequence are: because printing factories generally do not have gluing equipment and technology, labels need to be glued by outsourcing, and thus, the production period is long (the industry common practice is to deliver the labels for 21 days), and the production cost of small-batch label orders (commonly called short orders) is high.

The Chinese invention patent 'ink edge anti-counterfeiting method and ink edge anti-counterfeiting network identification system (CN 106096971B)' authorizes the technical scheme of the applicant for anti-counterfeiting by using ink edge sawteeth, and comprises the steps of printing codes/pictures and texts on a printing stock, and randomly deforming the edges of the codes/pictures and texts ink to generate personalized ink edge sawteeth; carrying out enlarged shooting on the printed codes/pictures and texts so as to shoot and obtain the ink edge sawtooth characteristic information and the code information; the ink edge sawtooth characteristic information and the corresponding coding information obtained by amplification shooting are stored in an anti-counterfeiting network identification system database, namely a cloud database, and are used as anti-counterfeiting characteristic information for the public to use a camera mobile phone to check the authenticity.

The study showed that: after a counterfeiter obtains the ink edge sawtooth image of the code or the image and text by a high-definition scanning method, very vivid ink edge sawtooth can be printed and copied by a plate printing process such as an offset press, so that the software identification difficulty of the anti-counterfeiting checking system is increased, and the checking accuracy is reduced.

How to increase the difficulty of copying and forging ink edge sawteeth, how to improve the inspection accuracy, how to shorten the production period and how to reduce the production cost of short bills is always an ink edge anti-counterfeiting method and an ink edge anti-counterfeiting network identification system (CN 106096971B) and an anti-counterfeiting industry, and a technical problem to be solved is urgently needed.

Disclosure of Invention

The purpose of the invention is as follows: the double-layer anti-recovery label is printed through, so that the production period is shortened, the production cost of a short single is reduced, the copying and counterfeiting difficulty of ink edge sawteeth is increased, the touch inspection of the public is facilitated, and the inspection accuracy is improved.

The invention relates to a print-through double-layer recycling-prevention label, which comprises a removable surface layer and a non-removable bottom layer (after being pasted for use), wherein a release agent layer is arranged between the surface layer and the bottom layer, and a removable structure is formed between the surface layer and the bottom layer by the release agent layer; the method is characterized in that: the surface layer is provided with a plurality of holes; because the deeper the hole, the more obvious the hand touch feeling, the better the hole depth H is more than or equal to the surface layer thickness, and H is 0.01-1 mm, or 0.02-0.8 mm, or 0.05-0.35 mm, or 0.1-0.2 mm, or 0.05 mm; the surface layer and the bottom layer in the hole are printed with codes/pictures, some ink marks forming the codes/pictures are printed on the surface layer, and other ink marks forming the codes/pictures are printed on the bottom layer through the hole. Preferably, the ink on the face layer and the ink on the bottom layer in the hole (equal upper and lower portions) are spliced into a complete three-dimensional code/graphic pattern.

Preferably, the print-through double-layer recycle resistant label has a surface tension L of the face layer₁Surface tension L with the underlayer₂The ratio of k = L₁/ L₂K is more than or equal to 1.2, or 1/k is more than or equal to 1.2; the coding/graphic ink has ink edge serrations. In order to increase the difficulty of forgery, it is preferable to set k ≧ 3, or 1/k ≧ 3, so that the difference in ink along the jaggy between the surface layer and the bottom layer is more pronounced.

Preferably, the thickness of the bottom layer of the print-through double-layer recycling-prevention label is more than or equal to 0.02mm, 0.03mm, 0.04mm, 0.05mm, 0.1mm or 0.2 mm. This is so because the thicker the base layer, the less likely it is that the laser will damage (i.e., penetrate) the base layer and cause substantial waste when it is engraved in the face layer. Preferably, in order to make the hand feel more obvious and to make the ink show through to the bottom layer sufficiently, the diameter (i.e. width) of the holes is preferably 0.06-6 mm, or 0.3-3 mm, or 1.5-3.5 mm.

Preferably, the metal ink layer is additionally arranged in the bottom layer of the print-through double-layer recycling-preventing label, so that the thickness of the bottom layer is further increased, and the bottom layer is prevented from being burnt through by laser.

Preferably, the holes of the print-through double-layer recycling-prevention label are laser-engraved holes, and can be mechanical-cut holes; alternatively, the label face layer is made of mesh material (such as gauze); alternatively, the hole has a raised edge and the hand touches the hole to a rough touch.

Preferably, the raised edge of the print-through double-layer recycle-resistant label is a pimple formed by melting of the material of the face layer (formed by the sharp change in temperature during laser engraving of the hole).

Preferably, the print-through double-layer recycle-resistant label has raised edges that are pimples formed by melting of the overlaminate layer on the face layer. The study showed that: because the surface layer and the coating layer have different thermal shrinkage strengths, when the holes are engraved by laser, the coating layer is shrunk and melted to form a ring of pimples by the sharply changed temperature.

Preferably, the color of the hole edge facing is different from the color of the underlying layer within the hole. Thus, it is almost impossible, i.e. more difficult, to reproduce the counterfeit because of the error of the overprinting machine, if the counterfeiter wants to accurately locate the boundary between the color of the edge of the hole to be reproduced and the color of the bottom layer in the hole.

Preferably, the base layer is a paper layer or film layer cut into small pieces. In other words, it is preferable to cut the bottom sheet 2 into pieces so that the bottom sheet of paper/film material is difficult to be completely removed and recycled by counterfeiters.

Preferably, the code and the text are combined into one, in other words, the code is used as the text.

Thus, after the label is attached to the product, the counterfeiter can only lift the surface layer but not the bottom layer. The ink on the bottom layer in the hole is necessarily retained on the product along the saw teeth, so that the ink edge characteristic information cannot be completely recovered, and the recovery counterfeiting can be effectively prevented.

Compared with the prior art, the invention can produce the following beneficial technical effects.

First, cannot replicate: the current plate printing process transfers the ink image and text to the contacted printing stock through a printing plate. Because the bottom layer in the hole is lower than the surface layer, the printing plate can not be contacted, so that the counterfeiter can not transfer the ink which is wanted to be forged into the hole of the depression along the anti-counterfeiting feature such as the sawtooth by using the printing plate, and particularly can not transfer the ink which is wanted to be forged into the corner area (namely the dead angle area) of the hole along the sawtooth by using the printing plate. If a counterfeiter also adopts a plateless printing process such as jet printing, ink marks sprayed into holes are inevitably and rapidly diffused and deformed, and ink which is supposed to be counterfeited is inevitably different from an original plate along a sawtooth, so that software of an anti-counterfeiting checking system is easily identified, and the product of the invention has the characteristic of being incapable of being copied.

Secondly, the production period can be greatly shortened: some anti-counterfeiting information such as ink marks and the like forming codes/pictures and texts can be printed on the bottom layer through holes, so that the defect of the existing process sequence in the background technology is overcome, the production period is greatly shortened, the external cooperation gluing is avoided, the delivery date of a label order can be shortened from 21 days to 1 day, and even the label order is immediately available; the production cost of the short bills is reduced.

Thirdly, bare-handed touch examination: the public can touch the holes with hands to confirm that the holes exist really, and then the mobile phone with the camera is used for checking the authenticity. The invention can obtain reliable checking conclusion by using the association double-insurance mechanism of combining the hand check and the machine check, thereby achieving the effect of improving the checking accuracy.

Fourthly, the complete recovery cannot be carried out: if the fake producer illegally takes off the label, only the surface layer can be taken off, but the bottom layer cannot be taken off, the bottom layer is necessarily remained on the product, and anti-counterfeiting information such as a complete code/image and the like is divided into two parts, so that the fake producer is prevented from completely recycling the label, and the label is prevented from being pasted on a fake product after being recycled.

Detailed Description

The first embodiment.

Ordering a tamper-evident sticker having a face layer 1 preferably 0.08mm thick and a back layer 2 preferably 0.05mm thick as shown in FIG. 3, and ensuring a surface tension L of the back layer 2₂Greater than surface tension L of face layer 1₁. As shown in FIGS. 1 and 2, 0.08mm thickFace layer 1 (e.g., 80 grams/m)²Coated paper) some holes 3 with a diameter of 1.5mm were engraved with a laser engraving machine. In order to avoid the laser engraving holes 3 in the surface layer 1, which damages (i.e. burns through) the bottom layer 2 and causes a lot of waste products, a method of increasing the thickness of the colored background layer 7 can be adopted. For example, a white ink is applied to a thickness of 20 μm or more by an engraved gravure plate to be used as the colored background layer 7; for another example, a layer of 17g/m is applied²The above tissue paper is used as the colored background layer 7, and preferably the tissue paper is cut into small pieces having an area of less than 5mm x 5mm, thereby turning the base layer 2 into a piece layer. In order to prevent the laser from burning through the bottom layer 2 to cause a large amount of waste products, it is preferable to coat a metal ink layer 11 which is difficult to burn through by the laser below the colored background layer 7. In other words, metal ink layer 11 thickens base layer 2, blocking the laser energy.

A code spraying machine is adopted to spray and print the code 4 in the form of a two-dimensional code and the picture and text 5 in the form of starlight on the anti-uncovering self-adhesive material, so that partial ink marks 13 penetrate through the holes 3 to be printed on the bottom layer 2, the ink marks are diffused or shrunk on the bottom layer 2 to form ink edge sawteeth 9, and the other part of ink marks fall on the surface layer 1, so that the ink marks on the surface layer 1 and the ink marks (the upper part and the lower part) on the bottom layer 2 in the holes 3 are spliced into a complete pattern of the code 4/the picture and text 5 in a three-dimensional structure.

Preferably, because of the surface tension L of the underlayer 2₂Greater than surface tension L of face layer 1₁Therefore, the ink formed on the bottom layer 2 in the hole 3 is larger along the serrations 9.

With reference to the 'ink edge anti-counterfeiting method and the ink edge anti-counterfeiting network identification system (CN 106096971B)', the characteristic information of the code 4 and the ink edge sawteeth 9 formed by spreading the code 4 is collected and stored in a cloud database as anti-counterfeiting characteristic information corresponding to the code 4 to be used as record information for the public to check the authenticity. And finally, adhering the prepared print-through double-layer recycling-prevention label to a product.

Therefore, before purchasing the product, the consumer can touch the hole 3 on the surface layer 1 with a hand to confirm that the hole 3 is really existed, and then the camera phone is used for scanning the code to check the truth. The invention checks the authenticity by the association double-insurance mechanism combining the manual check and the machine check, thereby obtaining a reliable checking conclusion and achieving the effect of improving the checking accuracy.

Example two.

Ordering a tamper-evident adhesive transparent plastic film material as shown in FIG. 3, wherein the transparent surface layer 1 has a thickness of preferably 0.025mm, and the white bottom layer 2 has a thickness of preferably 0.045mm, to ensure the surface tension L of the bottom layer 2₂Greater than surface tension L of face layer 1₁. Top layer 1 (e.g., 25 g/m) at 0.025mm thickness²Film of (2), plus 12 g/m²The plastic film coating layer 12 is formed by engraving holes 3 with a diameter of 1.5mm by a laser engraving machine. In order to avoid the laser damaging (i.e. burning through) the bottom layer 2 and causing a lot of waste when engraving the hole 3, a method of increasing the thickness of the colored background layer 7 can be adopted. For example, under the colored background layer 7, a layer of metallic powder ink 11 that is harder to burn through by the laser is applied. In other words, the metal powder ink layer 11 thickens the bottom layer 2, blocking the laser energy.

Preferably, a raised edge 10 is made at the aperture to facilitate a public hand check of the authenticity of the hole 3. Preferably, the apertures produce a raised edge 10 after lamination of facing layer 1, as shown in fig. 4 and 5. The study showed that: the surface layer 1 and the film coating layer 12 have different thermal shrinkage strengths, and when the holes 3 are engraved by laser, the film coating layer 12 is shrunk and melted to form a ring of pimples by the sharply changed temperature, so that the required raised edge 10 is formed. This protruding edge 10 feels roughly, can make things convenient for public hand to touch inspection hole 3, and obvious perception hole 3 exists to bare-handed authenticity in confirming the hole. As shown in fig. 6 and 7, the pimples on the raised edge 10 are more random and rough.

A code spraying machine is adopted to spray and print the code 4 in the form of a two-dimensional code and the picture and text 5 in the form of starlight on the anti-uncovering self-adhesive film, so that partial ink marks 13 penetrate through the holes 3 to be printed on the bottom layer 2, the ink marks are diffused or shrunk on the bottom layer 2 to form ink edge sawteeth 9, and the other part of ink marks fall on the surface layer 1, so that the ink marks on the surface layer 1 and the ink marks (the upper part and the lower part) on the bottom layer 2 in the holes 3 are spliced into a complete pattern of the code 4/the picture and text 5 in the three-dimensional structure.

Example three.

An anti-uncovering adhesive transparent plastic film material as shown in figure 3 is ordered, and a surface layer 1 is required to be made of a mesh material. Referring to the two examples above, a print-through double layer recycle resistant label as shown in fig. 8 was produced. Therefore, before purchasing the product, the consumer can touch the hole 3 on the surface layer 1 with a hand to confirm that the hole 3 is really existed, and then the camera phone is used for scanning the code to check the truth. If a counterfeiter illegally opens the label, only the surface layer 2 shown in fig. 10 can be removed, and the bottom layer 2 cannot be removed. In other words, only the substrate 2 as shown in fig. 9 can be left on the product, and in particular the partial ink marks 13 of the code 4 that are telegraphed through the holes 3 on the substrate 2. The result is: the anti-counterfeiting information such as a complete code 4/image and text 5 is divided into two parts, so that a counterfeiter can be prevented from completely recycling the label, and the label can be prevented from being pasted on a counterfeit product after being recycled. The production process sequence of the invention avoids external cooperation of gluing and can greatly shorten the production period. Practice proves that: the delivery date of the label order can be shortened from 21 days to 1 day, and even is immediately desirable.

The image and text 5 can be any characters, figures, lines and the like formed by ink. The holes 3 of the invention can be designed according to the needs of users, the aperture size can be adjusted, the density can be changed, and the arrangement pattern can be selected, for example, the holes 3 shown in fig. 8 are arranged on the label surface layer 1 in a full-page manner.

The technical solution provided by the present invention is described in detail above. The principles and embodiments of the present invention are explained herein using specific examples, which are presented only to assist in understanding the method and its core concepts. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall into the protection scope of the present invention.
