Problems solved by technology

[0004] However, 3D printing technology is difficult to apply in the packaging industry. The main reasons are: 1. At the present stage, 3D printing is realized through grating stereo imaging technology, that is, grating sheets are required.
2. The requirements for printing accuracy and grating composite accuracy are quite high, and the reject rate is high
The thickness of the lenticular film is far more than that of general packaging materials (such as packaging pap

Embodiment Construction

[0046] like figure 1 As shown, the invention discloses a printing method of a 3D pattern, comprising the following steps:

[0047] Step W1: making a multi-angle motion grating pattern;

[0048] Step W2: gravure printing or flexo printing the information medium layer;

[0049] Step W3: Embossing the grating.

[0050] In step W2, the information medium layer is printed on the surface of the printed matter, the curing degree of the information medium layer is controlled by controlling the energy of the ultraviolet lamp, and the hardness of the information medium layer is controlled by controlling the curing degree of the information medium layer.

[0051] In step W2, the drying degree of the information medium layer is 35-40%, specifically manifested as a surface conjunctiva, and the entity remains flexible and plastic.

[0052] In step W3, the following steps are included:

[0053] Q1. Before embossing, lay a layer of information medium on the full version or partially;

Abstract

The invention provides a 3D pattern printing method which comprises the following steps of first, manufacturing a multi-angle dynamic raster pattern, second, printing an information dielectric layer in a gravure or flexible mode, and third, coining a raster. The 3D pattern printing method has the advantages that offset printing or gravure printing is combined with the coining information dielectric layer to form the raster to achieve 3D pattern conversion, and the method can be achieved on a packaging box through direction printing.

Description

technical field [0001] The invention relates to the field of printing, in particular to a printing method of 3D patterns. Background technique [0002] Multi-angle dynamic patterns can be easily realized through 3D printing technology. 3D three-dimensional printing technology has developed very fast in recent years. 3D three-dimensional printing breaks the flat, static, and single effect of traditional printed matter, adds vitality to printed matter, and makes it stand out in the fiercely competitive market. [0003] There are two ways to print 3D three-dimensional patterns or multi-angle dynamic patterns: 1. Print the three-dimensional pattern on paper or other materials first, and then compound the lenticular sheet; 2. Print the three-dimensional pattern on the lenticular sheet directly. [0004] However, 3D printing technology is difficult to apply in the packaging industry. The main reasons are as follows: 1. At the present stage, 3D printing is realized by lenticular s...
