[0025] Please refer to Figure 1 and Figure 2 It is shown that the embodiment of the present application provides a multi-color digital holographic positioning anti-fake mark sticker, which comprises: a base film layer 1; an information unit layer arranged on the lower film surface of the base film layer 1, the information unit layer comprising a digital color layer 2, a molded holographic layer 3 and a protective unit layer arranged in turn from top to bottom, the lower surface of the protective unit layer being adhered to a release layer 7, the digital color layer 2 comprising a color pattern layer formed by a digital inkjet printer with a multi-color module; and a three-dimensional display layer and a surface protective film 10 arranged on the upper film surface of the base film layer 1.

The printing can reduce the problems of large product scrap and time-consuming and labor-intensive caused by positioning errors and ink leakage in multi-color printing. The molded holographic layer 3 is formed by coating material and molded by a holographic molding plate, which can facilitate the display of holographic effects. The protective unit layer is used to protect the digital color layer 2 and the molded holographic layer 3, and is connected to the release layer 7 by adhesion. The release layer 7 can be removed and attached to the carrier 11 including a wine bottle and a packaging box by adhesion after the release layer 7 is removed.

The three-dimensional display layer is used to display the information content of the information unit layer, and the surface protective film 10 protects the three-dimensional display layer.

[0027] Through the technical scheme, the base film layer 1 can be used as the support and manufacturing of the information unit layer and the stereoscopic display layer and the like, and can be adhered to various wine bottle bodies, packaging boxes, ornaments after the release layer 7 is torn off, and the digital color layer 2 formed by the multi-color module digital inkjet printer can be sprayed, the holographic layer can be fully coated and molded on the digital color layer 2, and the multi-color digital holographic positioning anti-fake mark can be obtained by the full coating and molding.

Meanwhile, the stereoscopic display layer can improve the stereoscopic display effect and enhance the anti-fake effect.

[0028] In an embodiment, the molded holographic layer includes holographic pattern grooves formed by a coating material being molded.

[0029] The molded holographic layer is formed by the coating material coated on the digital color layer 2 being molded by the holographic molding plate, and the holographic pattern grooves are formed, and the holographic pattern grooves are matched with the color pattern in position, so that the holographic display of the pattern information can be better. In the specific implementation process, the coating material is composed of 20% butanone, 40% ethyl ester, 30% amine-based resin, 8% acrylic resin, 2% rosin resin, and the balance of auxiliary agents, the coating speed is 100 m / min, and the molded holographic layer is molded with the holographic molding plate, and the molding temperature is 155-230°C. It can be understood that the holographic positioning needs to be positioned by the cursor device assisted positioning when each layer is made layer by layer, so that each layer can be accurately set at the predetermined position.

[0030] Further, the stereoscopic display layer includes a gold stamping bottom oil layer 8 and a gold stamping film layer 9 arranged from bottom to top, and the gold stamping bottom oil layer 8 is made of UV light curing ink material.

[0031] In this way, the gold stamping bottom oil layer 8 of the UV light curing ink material can form a dynamic light change effect with the molded holographic layer 3, enhance the stereoscopic effect, and the naked eye can quickly identify the authenticity, and the gold stamping film layer 9 can enhance the metal luster and stereoscopic effect, and the smooth surface of the UV ink curing can enhance the reflection performance and form a clear visual contrast. In the specific implementation process, the printing thickness of the gold stamping bottom oil layer 8 is 0.4-1.2 mm; the gold stamping film layer 9 is heated by a gold stamping machine to stamp the gold stamping film layer 9 onto the gold stamping bottom oil layer 8, and the stamping temperature is 105-125°C. The gold stamping film layer 9 is a stamping material made of a metal foil coated on a thin film base and vacuum evaporated.

[0032] In order to protect the stereoscopic display layer, further, the gold stamping film layer 9 is further provided with a surface protective film 10, and the surface protective film 10 is made of UV light-cured transparent ink material. The surface protective film 10 is printed on the gold stamping film layer 9 by screen printing method, and the surface protective film 10 is made of UV light-cured transparent ink, which can play the roles of wear resistance, scratch resistance, water resistance and alcohol resistance.

[0033] In actual use, the multi-color digital holographic positioning anti-fake mark has a use state, in which the release layer 7 is torn off, and the main body of the multi-color digital holographic positioning anti-fake mark is attached to the carrier 11.

[0035] In a preferred embodiment structure for protecting the unit layer, the protective unit layer comprises an aluminum plating layer 4 and a protective layer 5 arranged in sequence from top to bottom, and the protective layer 5 is attached to the release layer 7 through the adhesive layer 6.

[0036] The aluminum plating layer 4 of the protective unit layer can form a high-reflective metal surface, which, in combination with the embossed holographic layer 3, can better present the dynamic light change effect and improve the visual recognition.

The release film can be used to transfer the whole pattern to another article carrier 11, so as to ensure that the pattern is displayed neatly and regularly.

[0039] Preferably, the base film layer 1 has a thickness of 50-100 μm. The base film layer 1 with such thickness can better support and make the film layers such as the information unit layer and the stereoscopic display layer.

[0040] In the making process, the multicolor digital holographic positioning anti-fake label is pasted on the base film layer 1, and then the digital color layer 2, the molded holographic layer 3, the aluminum plating layer 4, the protective layer 5, the adhesive layer 6 and the release layer 7 are made on the reverse side of the base film layer 1, and then the gold stamping primer layer 8, the gold stamping film layer 9 and the surface protective film 10 are made on the front side of the base film layer 1 in sequence, and thus the multicolor digital holographic positioning anti-fake label can be obtained.

[0041] In summary, the multicolor digital holographic positioning anti-fake label has the following beneficial effects:

[0042] 1. The multicolor digital holographic positioning anti-fake label is also a baking-free double-color or multicolor digital holographic positioning anti-fake paper, which uses a transfer film as the carrier 11, and the base film layer 1, the digital color layer 2, the molded holographic layer, the aluminum plating layer 4, the protective layer 5, the adhesive layer 6, the gold stamping primer layer 8, the gold stamping film layer 9 and the surface protective film 10 are transferred to various wine bottle bodies, packaging boxes and decorations, and the adhesive layer 6 can attach the base film layer 1, the digital color layer 2, the molded holographic layer, the aluminum plating layer 4, the protective layer 5, the gold stamping primer layer 8, the gold stamping film layer 9 and the surface protective film 10 to the various wine bottle bodies, packaging boxes and decorations.
