Problems solved by technology

Self-adhesive and transfer film processes require PET film and glue, which requires many procedures, high production costs, high loss, and affects the environment
At the same time, the above-mentioned production processes all adopt the transfer method, and the holographic pattern cannot be accurately positioned, resulting in a decline in product quality and unable to fully meet market demand

Embodiment Construction

[0038] In the existing laser holographic process, the embossed holographic pattern on the nickel plate is transferred to the PET film by hot pressing, and the PET film with the laser holographic pattern is obtained. Its microstructure is as follows: figure 1 As shown, it consists of an aluminum coating layer 6, a release layer 7 and a PET film layer 8. There are two main types of laser holographic technology applied to printed matter: self-adhesive and transfer film. The self-adhesive process is to coat the laser holographic PET film with a layer of water-based glue and combine it with the release paper. After die-cutting, peel off the PET film and paste it on the printed matter. The transfer film process is to apply a layer of hot melt adhesive on the back of the laser holographic PET film, and use a hot stamping machine to heat and press the PET film to peel off and iron the printed matter. The microstructure of this printed matter is paper layer 1, ink layer 2, varnish lay...

Abstract

The invention discloses a hot-pressing printing method. The hot-pressing printing method includes the following steps that an embossed embossing nickel plate is manufactured; ink is printed; gloss oil is printed; holographic patterns are printed in a hot-pressing mode. A piece of printed matter with the holographic patterns is obtained through the method and comprises a paper layer, an ink layer and a gloss oil layer, wherein the gloss oil layer is provided with the holographic patterns. The laser holographic patterns are directly positioned and printed on the gloss oil layer on the surface of the printed matter in a hot-pressing mode through a flat pressing printer, the transfer technology is not adopted, and thus raw materials such as PET films and glue are saved, and the environment is protected; the used gloss oil is used originally for the printed matter, and thus extra cost is not added. Meanwhile, the technical problem that positioning is not accurate in the prior art is solved through an original positioning system of the printer, and the expression effect of the holographic patterns is substantially improved.

Description

technical field [0001] The invention relates to a printing method, in particular to a printed matter with a holographic pattern and a printing method thereof, belonging to the technical field of packaging printing. Background technique [0002] The laser holographic pattern has the advantages of changing colors from different viewing angles and reflecting the three-dimensional visual effect of the pattern. Generally speaking, laser holography first uses the principle of laser interference and diffraction to expose on a relief-type photosensitive material (photoresist), develop it to obtain a master plate, and then go through an electroforming process to produce an imprinted nickel plate. The embossed holographic pattern on the nickel plate is transferred to the PET film by means of a method to obtain a PET film with a laser holographic pattern. It is then applied to printed matter through different processing techniques. [0003] Laser holographic pattern is widely used in...
