3D cat eye pattern

Abstract

The invention provides a 3D cat eye pattern, which is provided with a base film, a separation layer, an imaging layer, a molding pressing layer, a digital printing layer, an aluminum plating layer anda glue layer in sequential lamination, wherein the base film is conveyed by a conveying mechanism; the base film is laminated with the lamination layer through a molding pressing device; the base film is laminated with a digital spray printing layer through a spray printing deice; a detection device is arranged between the molding pressing device and the spray sprinting device; a detection deviceis a camera; an unreeling device and a reeling device are arranged at the two ends of the conveying mechanism. The corresponding spray printing lamination printing can be performed according to the concrete condition of the bottom color patterns; the problem of unprecise lamination printing due to irregular change of the bottom color patterns is solved; the precise positioning of the multilayer pattern is realized, so that the pattern has the layered feeling and anti-counterfeiting effects.

Description

Technical field [0001] The invention relates to the technical field of laser anti-counterfeiting paper preparation, in particular to a 3D cat's eye pattern. Background technique [0002] Laser anti-counterfeiting paper or film has been widely used in the packaging and printing industry, especially high-end packaging such as cigarette packets, wine boxes, cosmetics and other packaging boxes. There are many applications. It not only has a beautiful appearance, but also has a certain anti-counterfeiting effect. This laser component Two are always full version, that is, they do not require location restrictions, which are already mature applications, and the other is that requires precise positioning of the location. For example, the solution in the published patent application CN102400411A, multiple positioning Laser anti-counterfeiting printing paper. The printing paper first comes from the laser film. The base film transfers the holographic information on the master to the film th...

[0002] Laser anti-counterfeiting paper or film has been widely used in the packaging and printing industry, especially high-end packaging such as cigarette packs, wine boxes, cosmetics and other packaging boxes. There are many applications. It not only has a beautiful appearance, but also has a certain anti-counterfeiting effect. The two are always full-page, that is, there is no need for position restrictions. This kind of application is already very mature, and the other one needs precise positioning with requirements on the position. For example, the scheme in the published patent application CN102400411A, multiple positioning Laser anti-counterfeiting printing paper, the printing paper first comes from the laser film, and the base film transfers the holographic information on the master plate to the film through molding equipment under high temperature and pressure, and then transfers the holographic information on the film to the paper On the surface, anti-counterfeiting laser paper is formed, because the film is mostly pressed out in rolls, because the film itself is relatively easy to deform, and it is easier to deform under temperature, tension, and pressure, so the laser pattern on the mold is also changed. , the same changing original film is transferred to paper and undergoes a process of unwinding and compounding, stripping, etc. The paper that comes out is also changing. In the same format, the distance between patterns and the size of patterns are all changing, and the commonly used Regardless of whether the printing equipment is gravure printing or offset printing, the pattern in a format is fixed. It is unrealistic and impossible to achieve accurate positioning in reality by using the fixed pattern to locate the changing pattern. This is also an urgent need in the industry. The problem to be solved, how to combine the holographic pattern with printing, increase the richness and layering of the pattern, and increase the anti-counterfeiting is a problem to be solved by industry technicians
