Problems solved by technology

This kind of production method is usually aimed at the processing and production of the whole plate, and due to the characteristics of the grating mold roll, this method can only produce the grating sheet with a single line width and line density. When making sheets, it is necessary to replace the corresponding grating mold roller, which is inconvenient to process; moreover, the surface of this type of grating mold roller and its tiny grooves require high precision during production, and the production cost and maintenance cost of this type of grating mold roller are relatively high. High, it is unrealistic to make multiple types of grating mold rolls corresponding to the local cylinder area

Embodiment 1

[0020] In this embodiment, a method for manufacturing a spray-printed lenticular lens plate is provided, which is first placed on the front surface of a transparent PS substrate plate with a thickness of 2 mm, and the entire substrate plate is used as a selected area. UV varnish is a printing fluid, and a Canadian Océ UV flatbed printer is used as the printing equipment. figure 1 As shown, the line density of 40 lines / inch is set on the equipment, and the line width is 0.6mm for equidistant printing, and the initial printing process is performed. After the initial printing is completed, a single-layer UV varnish line array is formed , Due to the fluidity of the varnish itself, the casting is like figure 1 In the state of the top image, the UV light curing system of the UV flatbed printer cures the sprayed layer to form the first layer of linear lenticular lens 1, and complete the initial printing process;

[0021] Maintain the initial printing position of the varnish nozzle. At th...

Embodiment 2

[0026] Generally, depending on the thickness of the substrate plate, the width and height of the grating lenticular lens need to be adjusted reasonably (the thickness of the surface substrate plate in the prior art needs to be increased, and the width and height of the grating lenticular lens need to be reasonably increased). Therefore, when the thickness of the transparent substrate is larger When it is high, in order to achieve a better visual effect, it can be made by reasonably reducing the density of the printing line and increasing the height of the cylindrical arch.

[0027] In this embodiment, glass with a thickness of 4mm is used as the substrate, and on its front side, the entire substrate plate is used as the selected area, transparent UV varnish is used as the inkjet liquid, and the Canadian Océ UV flatbed printer is used as the inkjet. Printing equipment, and such as figure 1 As shown, set a line density of 10 lines / inch on the equipment, line width 2.4mm for equidist...

Embodiment 3

[0031] In this embodiment, it is first placed on the front surface of a transparent PP substrate board with a thickness of 2.3mm, and the figure 2 The general pattern of windmill 41 and blade 42 is the selected area, and the transparent UV varnish is used as the printing liquid, and the Japanese mimaki UV flatbed printer is used as the printing equipment. figure 1 As shown, the line density of 45 lines / inch is set on the equipment, and the line width is 0.55mm for equidistant printing, the first printing process is carried out, the first printing process is carried out, and the first printing is completed to form a single layer After the UV varnish line array, due to the fluidity of the varnish itself, the casting becomes like figure 1 In the state of the uppermost image, the UV curing system of the UV flatbed printer cures the sprayed layer to form the first layer of linear lenticular lens 1, completing the initial printing process;

[0032] Maintain the initial printing position...

Abstract

The invention discloses a spraying and printing lenticular grating plate, a spraying and printing lenticular grating 3D (three-dimensional) picture and a manufacture method of the plate. The method includes the steps: taking UV (ultraviolet) oil as spraying and printing liquid, linearly and repeatedly spraying, printing and curing a selected area on the front of a transparent substrate by a UV flat printer 3-6 times to prepare a lenticular area; equidistantly spraying and printing the selected area according to the primary spraying and printing line density of 10-50 lines / inches and the primary spraying and printing line width of 0.5-2.4 millimeters; repeatedly spraying and printing the same area according to the same line density and the spraying and printing line width sequentially contracted by 6%-15% to prepare the spraying and printing lenticular grating plate; comparing a profile and line distribution of the lenticular area of the spraying and printing lenticular grating plate, directly printing grating textures on the back of the grating plate to form a grating texture area, or printing corresponding grating textures on a bottom plate layer, and sticking the corresponding grating textures on the back of the spraying and printing lenticular grating plate to prepare the spraying and printing lenticular grating 3D picture. According to the method, pre-production cost can begreatly reduced, a plane and a three-dimensional image form changeable pattern effects, production is simple and convenient, and integrated degree is higher.

Description

Technical field [0001] The invention relates to grating manufacturing technology and products thereof, in particular to a spray printing type lenticular grating plate, a spray printing type lenticular grating 3D picture and a manufacturing method thereof. Background technique [0002] The current manufacturing method of lenticular grating is to use a grating mold roll with a plurality of grooves on the outer circumferential surface to squeeze the grating sheet to produce a sheet plate with a cylindrical lens on the front and a smooth back. This kind of production method is usually aimed at the processing and production of the whole board, and due to the characteristics of the grating mold roll, this method can only produce grating sheets with a single line width and line density. For gratings with different line widths and line densities, For sheet material, the corresponding grating mold roll needs to be replaced, which is inconvenient to process; and the surface of such grating...
