Problems solved by technology

These two processes are inseparable from grating film, and as a plastic product, grating film has three major defects in the application of packaging and printing products: the material is not environmentally friendly, the application cost is high, and the packaging applicability is poor
[0006] The pattern printed by the printing process in the prior art is easy to be blurred, not clear, and the dynamic sense is not enough

Embodiment 1

[0025] A method for preparing a 3D direct printing grating print, comprising the following steps:

[0026] (1) Plate making, according to the design drawings to make the printing plate, so that the output precision of the printing plate is 9500DPI, and the screen line number is 800LPI;

[0027] (2) Use the offset printing method to print the design pattern on the base paper, adjust the machine so that the dot shrinkage ratio of the pattern printing is 98%; at the same time, it is necessary to adjust the sharpness of the grating ink, 98% can prevent the printed groups from bleeding into each other The resulting pattern is not clear and looks unclean. After adding the grating layer, the visual color will expand to a certain extent, and it will shrink by 95-98% during printing, which can ensure that the visual pattern will be cleaner after adding the grating layer. , bright;

[0028] (3) Make a mold for grating ink, the resolution of the mold is 280LPI;

[0029] (4) printing gr...

Embodiment 2

[0035] A method for preparing a 3D direct printing grating print, comprising the following steps:

[0036] (1) Plate making, according to the design drawings to make the printing plate, so that the output precision of the printing plate is 9700DPI, and the screen line number is 700LPI;

[0037] (2) Use the offset printing method to print the design pattern on the base paper, adjust the machine so that the dot shrinkage ratio of the pattern printing is 95%; at the same time, it is necessary to adjust the sharpness of the grating ink, 95% can prevent the printed groups from bleeding into each other The resulting pattern is not clear and looks unclean. After the grating layer is added, the color will expand visually to a certain extent, and it will shrink by 95% during printing, which can ensure that the visual pattern will be cleaner and brighter after adding the grating layer. .

Abstract

The invention provides a preparation method for a 3D direct-printing grating printing product, and belongs to the technical field of printing. The preparation method for the 3D direct-printing gratingprinting product comprises the following steps: (1) carrying out plate making, enabling the output accuracy of a printing plate to be 9500-9700DPI, and enabling the screen ruling to be 700-800LPI; (2) printing a design pattern on raw paper by means of offset printing, and enabling the point shrinkage ratio of pattern printing to be 95%-98%; (3) producing a mold for grating ink, and enabling the resolution ratio of the mold to be 260-280LPI; (4) placing the mold on a grating ink layer, producing a 3D grating, and enabling the thickness of the grating ink layer to be 0.13-0.16cm; and (5) dryingand curing, demolding, and then obtaining the 3D direct-printing grating printing product. The preparation method for the 3D direct-printing grating printing product is capable of ensuring the definition of the observed pattern, and high in resolution ratio, and ensures the glossiness and three-dimensional effect of the pattern of the colored ink layer on the raw paper; and the change of an observation angle presents a dynamic effect, so that the pattern is higher in resolution ratio.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular relates to a method for preparing a 3D direct printing grating printed matter. Background technique [0002] 3D printing, also known as three-dimensional printing, usually refers to three-dimensional lenticular printing. It adopts a principle of simulating the distance between human eyes to produce space difference, records pixels of different angles and levels on the photosensitive material, and then uses the compounding of grating materials to present a three-dimensional effect on the two-dimensional plane image Even in virtual reality, people can clearly and clearly experience the wonderful fun of three-dimensional images by directly observing with their eyes without using any tools. 3D prints and three-dimensional Figure 1 The three-dimensional effect cannot be seen on the computer, but after the three-dimensional printed matter is printed, due to the particularity of the...
