In order to understand the features, contents, and advantages of the present invention, and the advantages thereof, the present invention will be described in conjunction with the drawings, and the description of the embodiments will be described in detail below. The use of the present invention and the accompanying drawings are not necessarily the true proportions and precise configurations of the present invention. Therefore, the scope and configuration of the attached drawings should not be construed as limiting the scope of the invention.

The advantages and features of the present invention, as well as the technical methods of the present invention, are described in more detail with reference to the exemplary embodiments and the accompanying drawings, and the present invention may be implemented in various forms and should not be construed as limited thereby. The embodiments of the present invention, and the embodiments of the present invention are intended to provide a more complete and complete and complete disclosure of the scope of the present invention, and The scope of the patent application is defined.

Please refer to FIGS. 1 and 2; FIG. 1 is an exploded perspective view of a card structure having a dot grating according to the present invention; and FIG. 2 is a screen printing dot dot of a card structure having a dot grating according to the present invention. A schematic diagram of the superposition of the first shading and the second shading. As shown, the card structure 100 of the present invention having a dot grating includes a dot grating coating layer 110, a texture layer 120, and a coating layer 130. The card structure 100 having a dot grating is formed by sequentially pressing and bonding the dot grating coating layer 110, the underprint layer 120, and the coating layer 130.

In other words, one side of the dot grating coating layer 110 has a plurality of screen printing dot dots 111 printed on the screen, and the touch can be felt when the surface is touched.

The shading layer 120 is disposed on one side of the dot grating coating layer 110 having a plurality of screen printing dot dots 111, that is, the dot grating coating layer 110 does not have a plurality of screen printing dot dots 111. one side. The face layer 120 has a plurality of first shadings 121 (such as "TN" in FIG. 2) and a plurality of second shadings 122 (such as "5" in FIG. 2) on one side of the dot grating coating layer 110. The positions of the plurality of first shadings 121 respectively correspond to the corresponding screen printing dot dots 111; and the positions of the plurality of second shadings 122 are respectively between the corresponding screen printing dot dots 111 Having an offset distance, the offset distance of each of the second shadings 122 is proportional to the distance of each of the second shadings 122 from the starting point A of the card structure 100 having the dot grating, as shown in FIG. The direction arrow extending from the starting point A, the second shading 122 adjacent to it is further away from the starting point A, and the offset is larger. In other words, since the first shading 121 is fixed, It can also be found that the further the distance from the starting point A is, the larger the first shading 121 of the second shading 122 is, and the offset direction of each second shading 122 is the direction relative to the starting point A.

Wherein, the position of the screen printing dot dot 111 overlaps the position of the corresponding first shading 121, and is fixed; further, after the dot grating coating layer 110 is thermally pressed with the shading layer 120, A shading 121 is located in the corresponding screen printing dot dot 111. However, the starting point A can be set according to requirements and other considerations, and the second shading 122 will be offset from the starting point, and the offset distance of the second shading 122 farther from the starting point A The larger the offset mentioned here is, the second shading 122 is interlaced with the position of the corresponding screen printing dot dot 111, and the continuous uninterrupted moving image can be observed from different viewing angles. A shading 121 is generally fixed and overlaps the position of the screen printing dot dot 111. In addition, among the directions extending from the starting point A, the offset distances of two adjacent ones of the plurality of second shadings 122 may differ by 1 pixel; that is, one direction from the starting point A The offset distances of two adjacent ones of the plurality of second shadings 122 will differ by one pixel. However, the above is only an example and should not be limited to this.

The coating layer 130 is disposed on one side of the ground layer 120 opposite to the dot grating coating layer 110, that is, the bottom layer 120 does not have a plurality of first shadings 121 and a plurality of second shadings 122.

In addition, the screen printing dot dot 111 may be a convex lens structure, and the size of the screen printing dot dot 111 may be proportional to the thickness. However, before printing the dot printing dot 111, it is necessary to open a file to transfer out the dot pattern, and adjust the parameters such as the number of lines, angles and shapes, and modify the image processing such as edge, reverse, black and white. Thereafter, the file can be produced for subsequent printing of the dot printing dot dot 111.

Please refer to FIG. 3, which is a schematic diagram of a dot grating coating layer of a card structure having a dot grating of the present invention. As shown in the figure, the screen printing dot dot 111 is a convex lens structure, which is designed according to the formula, and the formula is as follows:

Where t is the focal length, that is, the thickness of the dot grating coating layer 110 plus the height of the dot printing dot dot 111; r is the radius of curvature of the screen printing dot dot 111; n is the refractive index, that is, used The refractive index of the material and the UV varnish used; D is the diameter of the screen printing dot dot 111; h is the height of the screen printing dot dot 111.

However, the principle of screen printing minimization is mainly based on superimposing lines of the same period to superimpose to generate a new pattern, which follows the following formula:

Among them, the W system is the size of the moiré; the P ₁ system is the first group period; the P ₂ system is the second group period; the θ system is the angle between the two groups of lines.

It is worth mentioning that the printed shading must be offset from the angle of the screen printing dot dot 111 so that any one cycle can correspond to the moire animation of the upper and lower dots. Since the screen printing dot dots 111 can be printed after the pressing, and the spacing and size of the screen printing dot dots 111 need to be fixed, if the distance between the dots is too close, the ink will stick together before the ultraviolet drying. Therefore, when designing, the screen printing dot dot 111 should not be too large to avoid the printing ink from expanding and sticking together. In addition, the ink viscosity is insufficient or the high temperature and high humidity environment causes the ink to flow to the side, so that the screen printing dot The height of the dot 111 is slightly lowered. However, when the screen printing dot dot 111 having a high film thickness is screen-printed, the lower the number of meshes, the more the effect can be exhibited. The present invention can use a 200-mesh screen, and the thickness of the screen emulsion is 12 um, which is printed. The thickness of the screen printing dot dot 111 is 30 um high. When the screen printing film thickness of the screen printing dot dot 111 is made, the ink liquid flows, so the UV type ink is used to instantaneously dry by ultraviolet light irradiation. However, the above is merely illustrative of the invention and is not intended to be limiting.
