Embodiment 1

[0026] Embodiment 1: as Figure 1-Figure 2 As shown, a laser digital inkjet printing method, through the online inkjet printing of multiple sets of digital nozzles, firstly through the inkjet printing of the first inkjet printing unit, to achieve graphic inkjet printing with a uniform flat bottom effect. When printing through the digital nozzle of the second printing unit, use the program to control the position of the nozzle, selectively print the position and shape of the graphic, and the value of the program to control the amount of ink droplets to adjust the thickness of the ink layer, ink droplets Due to the dual effects of gravity and surface tension on the surface of the printed matter, it will form pagoda lines with small tops and large bottoms. The second printing unit performs partial UV varnish jet printing on the mirror background color. The ink thickness of the UV varnish layer is 0.2±0.05mm. Viewed from a different angle, the products all have a beautiful laser ...

Abstract

The invention discloses a laser digital jet printing method, which comprises a package printing stock and a transparent plastic packaging film packaged on the surface of the package printing stock, the surface of the package printing stock is provided with negative anti-counterfeiting layer lattice points, the surface of the transparent plastic packaging film is provided with positive decoding layer lattice points corresponding to the negative anti-counterfeiting layer lattice points, and the negative anti-counterfeiting layer lattice points are hidden patterns and characters. And the lattice points of the positive decoding layer hide the corresponding patterns of the pattern characters. The lattice points of the negative anti-counterfeiting layer and the lattice points of the positive decoding layer are very shallow, and cannot be copied without an original design file, so that the anti-counterfeiting property is very high; the lattice points in the pattern of the anti-counterfeiting layer are hemispherical, compared with printing lattice points, the anti-counterfeiting pattern made of the three-dimensional hemispherical lattice points is higher in stereoscopic impression, particularly, when a latent image pattern is made, the 3D shape of the lattice points forms the three-dimensional latent image pattern through reflection of light at different angles, and the anti-counterfeiting effect is better.

Description

technical field [0001] The invention relates to a laser digital jet printing method, which belongs to the technical field of laser digital jet printing. Background technique [0002] When sunlight passes through the prism, it will produce a colored light band effect, which is caused by the difference in the refractive index of the wavelength of different colors of light. In actual production and life, the surface of the printed matter is deliberately made to show this effect through process manufacturing, commonly known as laser printing. This kind of laser effect is more and more common in the application of packaging printed matter. At present, most laser processes are realized by laser imprint transfer process. The process is to prefabricate the laser nickel plate with laser processing technology, and then make the laser nickel plate to obtain the required processing format, and obtain the OPP laser transfer film by rolling embossing, and make the surface of the transfer...
