Problems solved by technology

These methods all have the disadvantages of complex process, high requirements for equipment precision and operator level, and thus high production cost. Moreover, when positioning holographic images, the positioning accuracy of these methods is not high, and the error is mostly about 0.3-0.4 mm, which is difficult to meet high requirements. Requirements for precision positioning and anti-counterfeiting
[0004] Due to environmental protection, transfer paper is widely used in packaging. During the production process of roll transfer paper, the film needs to be peeled off and then rewound. Due to the stress generated during the winding process, internal friction occurs, so the surface of the paper is scratched, and a large amount of waste products are often produced.
[0005] The configuration of the gravure printing machine is relatively flexible. For example, it is equipped with in-line hot stamping, in-line embossing, and in-line cross-cutting. There are media reports, but there is no relevant report on the in-line stripping configuration.

Embodiment 1

[0027] S1: Plate making process, making laser plates with graphic information;

[0028] S2: Coating process, using coating equipment to uniformly and densely coat a layer of release agent or imaging coating on the PET base film; the thickness of the release agent or imaging coating coated on the PET base film is 1.0 ~1.5g / m 2 .

[0029] S3: Aluminum plating process, the PET base film coated with a release agent or imaging coating on the surface and the aluminum material are installed in a vacuum evaporation machine, and the vacuum evaporation machine is vacuumed with a vacuum pump, and then the aluminum material is Heating to 1200°C-1400°C, so that the gaseous aluminum particles are deposited on the surface of the moving release agent or imaging coating, and then cooled to form a continuous and bright metal aluminum layer; the vacuum pump pumps the vacuum evaporation machine The vacuum degree of the vacuum should reach 1.3×10 -2 ~1.3×10 -3 pa. The thickness of the aluminu...

Embodiment 2

[0035] Scratch test of embodiment 2 finished transfer paper

[0036] Using the holographic transfer paper prepared in Example 1 (that is, the paper that has not passed through the gravure printing process), it is carried out with a cross-cut knife test according to the national standard GB / T9286-1998, and the transfer layer on the surface of the test product is scratched 10 times with a cross-cut knife. ×10 (100 pieces) 1mm×1mm small grid, the depth of the line and the bottom layer of the coating material; use a brush to clean the debris in the test area; stick the tested grid with 3M600 adhesive tape, and use an eraser to force it Wipe the tape to increase the contact area and strength between the tape and the measured area; grasp one end of the tape, quickly tear off the tape in the vertical direction (90°), and observe the situation where the coating in the grid is pulled off by the tape, the same position Conduct the same adhesion test twice, and the results after three ...

Abstract

The invention belongs to the field of printing, and in particular relates to a hologram text gravure positioning printing method. It includes a plate making process, a coating process, an aluminum plating process, a molding process, a composite process, a peeling process and a gravure printing process. In the present invention, the unpeeled reel transfer paper is directly unwound through the unwinder through the gravure printing on-line peeling, and the film of the transfer paper is peeled off through the in-line peeling unit first, and the paper material is directly introduced into the gravure printing unit for printing. It is of great significance to effectively solve the phenomenon of scratches caused by internal stress and improve the yield of production.

Description

technical field [0001] The invention belongs to the field of printing, and in particular relates to a hologram text gravure positioning printing method. Background technique [0002] Laser holographic image anti-counterfeiting technology is a stereoscopic photography technology. According to the principle of laser interference, laser holograms are produced by using the method of spatial frequency coding. It is a high-tech printing process using optical technology. It can not only reproduce the main image of the original object, but also show the different side shapes of the original object with the change of the observation line of sight. The laser holographic image uses the principle of white light diffraction grating to make the image effect changeable, colorful, colorful, and colorful. , clear layers, vivid and lifelike, high information and technical content, high technical content in the production and reproduction of laser holographic images, professional talents are r...
