Problems solved by technology

Correspondingly, if the design mechanism of individual paper product packaging is changed, the manufacturing cost will be increased
[0007] Based on the above existing anti-counterfeiting technologies, each has its own characteristics, but there are the same problems: special processing procedures are required, and production costs need to be increased

Embodiment 1

[0037] Example 1: as Figure 1-4Shown, a precision etching aluminized film gravure in-line composite transfer printing method. The method is as follows: when a conventional vacuum aluminized film production process is used to produce a vacuum aluminized film, high-temperature gaseous aluminum particles are deposited and cooled on the surface of the moving film substrate to form a continuous and bright metal aluminum layer, commonly known as vacuum aluminum plating. membrane. The invention pre-prints a layer of release resin ink pattern on the base film by prefabricating a precise etching gravure roll plate, so that when the high-temperature aluminum powder is deposited and cooled on the surface of the base material, a continuous and bright metal aluminum layer is obtained in the blank position. The metal aluminum layer at the position is repelled by the release resin, and its aluminized layer is only 45%-55% of the aluminized layer in the continuous blank position, so as to o...

Embodiment 2

[0064] Example 2: as image 3 As shown in the figure, a precision etching invisible anti-counterfeiting material gravure connection printing structure includes a white cardboard layer 1, a transfer glue layer 2, a varnish protective layer 3, an aluminum plating layer 4, and an anti-counterfeiting graphic layer 5 from the bottom to the top. and printed graphic layer 6.

[0065] like Figure 4 As shown in the figure, a printing method of precision etching invisible anti-counterfeiting material gravure on-line printing structure, the method is: the anti-counterfeiting graphic information is made into an anti-counterfeiting gravure plate by a laser precision etching process, and the plate is used on a PET base. Film surface processing During the primer coating process, release resin ink printing is performed simultaneously, and then vacuum aluminum plating is performed to obtain a PET aluminized film with precision etched anti-counterfeiting information content. A new type of pa...

Abstract

The invention discloses a precise etching aluminized film gravure online composite transfer printing method which comprises the following steps: prefabricating a precise image-text gravure roller plate by adopting a precise etching process, preprinting a layer of release resin ink pattern on a base film, depositing high-temperature aluminum powder on the surface of a base material, and obtaining a continuous and bright metal aluminum layer at a blank position when the high-temperature aluminum powder is cooled; under the exclusion of the release resin, the aluminum-plated layer of the metal aluminum layer at the pattern position is only 45-55% of the aluminum-plated layer at the continuous blank position, so that the aluminum-plated film material with the hidden pattern is obtained, and then the aluminum-plated film material with the hidden pattern is placed in gravure online transfer printing equipment for online transfer printing processing to obtain a final finished product. Synchronous production of anti-fake images and texts is achieved during conventional aluminum plating transfer production, the common surface anti-fake effect process in the market is changed, the anti-fake images and texts are hidden in the inner layer of the raw material, and the verification means is very simple. And a counterfeiter cannot counterfeit and manufacture without obtaining the original image-text, so that the anti-counterfeiting effect is good.

Description

technical field [0001] The invention relates to a method for precision etching aluminized film gravure on-line composite transfer printing, and belongs to the technical field of packaging and printing of paper products. Background technique [0002] With the development of society and the more prosperous commerce, manufacturers and consumers have higher and higher requirements for identifying the authenticity of products, which has spawned many anti-counterfeiting processes for packaging and printing products with mature applications. The summary and classification mainly include the following categories: [0003] 1. Optical anti-counterfeiting technology: It uses the multilayer dielectric film structure of thin film interference effect, grating structure and various types of holographic technology using the concept of information optics. These technologies mainly use the basic laws of scattering, reflection, transmission, absorption and diffraction generated when light inte...
