Hereinafter, with reference to the drawings will be described in detail. However, these drawings are for illustrative purposes only and the present invention is not limited thereto.

1 (a) to (c) is a view showing a flow chart and the printed matter of the three-dimensional printing method according to the first embodiment of the present invention.

Referring to (a) to (c) of FIG. 1, the three-dimensional printing method according to the first embodiment of the present invention includes a design step S100, a base material preparation step S200, and an embossing printing step S300. It is composed.

The drawing step S100 is a step of drawing an image pattern 30 including any one or more of a picture, a pattern, letters, and numbers. The pattern of the image pattern 30 can be drawn directly by the print producer, or drawn or selected using a computer, and the user's request for using the printed matter, for example, a commemorative photograph, a gargoyle, a corporate advertisement, etc. It may be formed on demand.

The base material preparation step (S200) is a step of preparing the base material 10 to print the image pattern 30, and may use various materials depending on the environment in which the printed matter is to be used. The base material 10 used in the first embodiment of the present invention is made of a transparent or translucent material.

Examples of the base material 10 of a transparent or translucent material include polyethylene (PE), polyethylene terephthalate (PET), polyvinyl chloride (PVC), polypropylene (PP), acrylic (PMMA), and polycarbonate (PC). It may be selected from ones such as synthetic resin, glass, lens, vinyl, liquid crystal display (LCD).

The embossing printing step (S300) is a step of three-dimensional screen printing the image pattern 30 so that the embossing effect appears by using the UV (Ultra Violet) ink 20 on the base material 10. (B) of FIG. 1 shows that the UV ink 20 is screen printed on only one side of the base material 10, and FIG. 1 (c) shows that the UV ink 20 is screen printed on both sides. As such, the UV ink 20 is printed to exhibit an embossing effect, so that the light reflected from the printed matter and incident to both eyes is refracted by the UV ink 20 to be seen in three dimensions without using a lenticular sheet.

Here, when using a lens, in particular a camera lens as the base material 10, it can be used as a lens that can impart various effects by the embossing effect. For example, the embossing effect of the UV ink 20 printed on the lens reduces the roughness of the skin when taking portraits as the light is refracted, and emphasizes the feminine skin. It will be able to function as a soft lens.

At this time, the UV ink 20 may be printed such that the embossing effect is displayed on one or both sides of the base material 10 according to the purpose of use of the printed matter. The UV inks 20 are printed to be spaced apart from each other by a predetermined distance, and the size or height of each of the UV inks 20, the spacing between each other, the angle of refraction of the incident light, etc. may be changed according to the purpose of use of the printed matter.

The UV ink 20 is an ink having a function of instant drying, low temperature, high speed productivity, pollution-free, and the like that can be hardened from the liquid phase to the solid phase by causing a photochemical reaction by ultraviolet rays. Strong resistance to chemicals, etc., there is no fear of backing and blocking.

UV ink 20 used in the present invention is selected from the group consisting of polyester acrylate, epoxy acrylate, urethane acrylate as the resin governing the basic properties, preferably urethane acrylate is preferably used. . In addition, the UV ink 20 uses acrylates as reactive diluents having viscosity adjustment, curability and adhesion of the ink, and a carbonyl compound that generates radicals from ultraviolet rays and reacts with urethane acrylate to cause polymerization. Done. In addition, polyethylene wax is used as an adjuvant of the pigment and the hardening agent.

As shown in (a) and (b) of Figure 2, the three-dimensional printing method according to the second embodiment of the present invention is almost similar to the first embodiment described above, the base material preparation step (S200) and the embossing printing step An image pattern printing step S300 for offset printing the image pattern 30 on one surface of the base material 10 is included between S400.

Then, the UV ink 20 is three-dimensionally screen printed so that the embossing effect is displayed on the opposite side on which the image pattern 30 is printed.

In the second embodiment of the present invention, the base material 10 is made of a transparent or translucent material, and the image pattern 30 offset printed on one side of the base material 10 is screened so that the embossing effect appears. The printed UV ink 20 makes it appear three-dimensional.

3 (a) and 3 (b) are diagrams showing a flow chart and printed matter of the three-dimensional printing method according to the third embodiment of the present invention.

Referring to (a) and (b) of FIG. 3, the third embodiment is configured similarly to the second embodiment, and the laminating step S400 is performed between the image pattern printing step S300 and the embossing printing step S500. It is configured to be.

Laminating is a method of coating the film 40 on the surface of the printed matter to enhance the gloss and extend the life. In the third embodiment of the present invention, the surface opposite to the base material 10 on which the image pattern 30 is printed. It is coated with a film 40 of polypropylene (PP) or polyvinyl chloride (PVC).

And, the embossing printing step (S500), UV (Ultra Violet) ink 20 to the film 40 of polypropylene (PP) or polyvinyl chloride (PVC) coated by the above-mentioned laminating step (S400) It is made by screen printing three-dimensional so that the embossing effect appears.

In the third embodiment of the present invention, the base material 10 is made of a transparent or translucent material, and is made of a film 40 or a transparent or translucent material, so that the printed image is offset on one side of the base material 10. The pattern 30 is seen in three dimensions by the UV ink 20.
