Problems solved by technology

[0003] Its disadvantages are as follows: First, in this method, there is a cooling and setting link in the production process for the uniformly spaced dot gratings produced by hot pressing. Improper control will bring the risk of grating deformation and lead to waste products. Second, the dot-shaped grating mold required by this method is an ultra-high-precision mold, and the manufacturing cost is high. Different products correspond to different molds, which is very inconvenient and costly in practical applications, which is not conducive to 3D The development of three-dimensional printing

Embodiment Construction

[0013] The production steps of specific embodiment:

[0014] First, use computer and related software to design corresponding electronic files, then make plates and print, and obtain the substrate 1 with three-dimensional graphic information attached;

[0015] Second, gravure printing is carried out on the substrate 1 carrying the three-dimensional graphic information, so as to realize the three-dimensional effect and part of the graphic and text is covered with transparent varnish;

[0016] Third, use the prefabricated grating mold to perform cold pressing on the post-press processing equipment, so that the corresponding grating 2 is produced on the surface of the substrate to produce a stereoscopic visual effect.

[0017] Among them, the dot-shaped grating 2 formed by cold pressing the prefabricated grating mold on the three-dimensional printing substrate coated with transparent materials, its corresponding parameters are as follows:

[0018] Spacing d=0.036mm;

[0019] An...

Abstract

The invention discloses a printing technique for showing a three-dimensional visual effect, and relates to a printing technique for directly showing the three-dimensional visual effect of patterns and characters. The printing technique needs to solve the following two problems: (1) eliminating the deformation of dot-like gratings formed by hot-pressing in order to decrease the reject rate and increase the production benefit; (2) reducing the application cost of three-dimensional printing. In order to solve the technical problems, the printing technique is implemented by the following technical scheme: the printing technique for showing the three-dimensional visual effect first prints synthesized three-dimensional patterns and characters on a printing stock (1), transparent varnish is coated on the surfaces of the patterns and the characters, and is pressed by a dot-like grating die matched with the patterns and the characters, so that an equidistant dot-like grating (2) is formed on the transparent material, and thereby the patterns and the characters show the three-dimensional visual effect. The printing technique is mainly applied to product packages, books, periodicals, advertisement and the like directly showing the three-dimensional visual effect of the patterns and characters.

Description

technical field [0001] The invention relates to a printing process for directly expressing stereoscopic visual effects of pictures and texts. Background technique [0002] Chinese patent application number 2010102575683, the application date is August 18, 2010, and the name of the invention is a method for expressing graphic and text stereoscopic visual effects. This invention application discloses a method for making pictures and texts have a stereoscopic effect, which is characterized in that: firstly, the synthesized three-dimensional pictures and texts are printed on paper, and a film is pasted on the surface of the pictures and texts, and the three-dimensional pictures and pictures made in advance are used to The regular hexagonal sphere dot-shaped grating mold matched with the text will form a dot-shaped grating after being hot-pressed by the hot stamping equipment, thereby producing a three-dimensional visual effect. [0003] Its disadvantages are as follows: First, ...
