Description

Technical Field

[0001] This invention relates to 3D visual effect graphic products, and in particular to a method for manufacturing a substrate-free 3D visual effect graphic product. Background Technology

[0002] 3D visual effect graphic products based on lenticular lenses are graphic display products that achieve stereoscopic visual effects using special optical principles and manufacturing processes. These products utilize the refraction and focusing effect of lenticular lenses on light, allowing the observer to see different images from different angles, thus producing a stereoscopic visual effect. A lenticular lens is an optical element with a tiny array of lenses, each lens focusing incident light to a single point. The arrangement of the lenses determines the position and shape of the focal point. When light passes through the lenticular lens, it is split into multiple directions, and light from each direction is focused at a different position, forming multiple images. These images are superimposed in the observer's eye, producing a stereoscopic visual effect. In the production process of 3D visual effect graphic products, the graphic information to be displayed is first created as a special pattern. This pattern contains all the information needed for viewing from different angles. Then, this pattern is printed or transferred onto the lenticular lens, allowing each lens to focus its corresponding image onto the observer's eye. 3D visual effects graphic products enable viewers to easily view graphic information with stereoscopic visual effects. These products have wide applications in advertising, exhibitions, education and other fields.

[0003] Currently, existing 3D visual effects graphic products require the combination of graphic printing and 3D dot-matrix or columnar lens lenticular sheets for production. Regardless of the shape of the lens lenticular sheet used, a certain thickness of lens lenticular sheet is required to refract the printed graphics and text under the lenticular sheet into a three-dimensional illusion effect.

[0004] The existing method for producing 3D visual effect graphic products involves first printing graphics on a substrate such as paper, and then bonding the printed substrate to a pre-made lenticular lens sheet with glue. 3D visual effect graphic products produced using this process are relatively thick.

[0005] Traditional methods for producing 3D visual effects graphics products make it difficult to create thinner 3D visual effects graphics products, resulting in significant limitations in their application and failing to meet the diverse requirements of packaging printing, such as being soft, thin, and fine.

[0006] In addition, traditional 3D visual effects graphic product array lenses are only made as a single sheet, which cannot flexibly meet the precise design requirements of graphic content.

[0007] It should be noted that the information disclosed in the background section above is only for understanding the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0008] The main objective of this invention is to overcome the deficiencies of the aforementioned background technology and provide a method for manufacturing 3D visual effect graphic products without a substrate.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A method for manufacturing a substrate-free 3D visual effect graphic product includes the following steps:

[0011] S1. Printing images on a substrate material pre-coated with an optical medium material image printing layer;

[0012] S2. Apply a curing adhesive composition for forming a lens to the printed surface of the substrate material on which the graphic is printed;

[0013] S3. Using a prefabricated 3D array lens mold, the curing adhesive composition coated on the substrate material is pressed and cured. The cured adhesive composition is then bonded to the optical medium material graphic printing layer. The adhesion of the substrate material to the optical medium material graphic printing layer is less than the adhesion of the curing adhesive composition to the optical medium material graphic printing layer.

[0014] S4. Peel the substrate material from the optical medium material graphic printing layer to obtain the substrate-free 3D visual effect graphic product.

[0015] Furthermore, the optical medium material graphic printing layer is a zinc sulfide or silicon oxide medium material that is vapor-deposited or electroplated on the substrate material.

[0016] Furthermore, the thickness of the optical medium material graphic printing layer is 100-300 nanometers, preferably 150-250 nanometers, and more preferably 200 nanometers.

[0017] Furthermore, the substrate material is paper or plastic.

[0018] Furthermore, the thickness of the cured adhesive composition is 10-100 micrometers.

[0019] Furthermore, the printing dyne value of the optical medium material graphic printing layer on the substrate material is 38-45, and the adhesion of the substrate material to the optical medium material graphic printing layer is less than the adhesion of the curing adhesive composition to the optical medium material graphic printing layer.

[0020] Furthermore, the 3D array lens mold is a metal or transparent mold; the 3D array lens mold is a flat plate or roller mold.

[0021] Furthermore, the 3D array lens mold is a full-size or partial array lens mold, and the substrate-free 3D visual effect graphic product is a substrate-free full-size or partial array lens 3D visual effect graphic product.

[0022] Furthermore, the 3D array lens mold includes a female mold roller engraved with a lens shape and a smooth mirror roller or flat template. After the tape composed of the curing adhesive composition, the optical medium material graphic printing layer and the substrate material is pressed together by the female mold roller and the smooth mirror roller, the substrate-free 3D visual effect graphic product composed of the curing adhesive composition and the optical medium material graphic printing layer is wound up by a first winding structure, while the substrate material is peeled off from the optical medium material graphic printing layer and wound up by a second winding structure.

[0023] A method for manufacturing a substrate-free 3D visual effect graphic product includes the following steps:

[0024] T1. Printing graphics on a substrate material pre-coated with an optical medium material graphic printing layer;

[0025] T2. Apply a curing adhesive composition for forming the lens onto a prefabricated 3D array lens mold;

[0026] T3. Using a prefabricated 3D array lens mold, the printed surface of the substrate material on which the graphic is printed is pressed and the curing adhesive composition is cured. The cured adhesive composition is bonded to the graphic printing layer of the optical medium material. The adhesion of the substrate material to the graphic printing layer of the optical medium material is less than the adhesion of the curing adhesive composition to the graphic printing layer of the optical medium material.

[0027] T4. Peel the substrate material from the optical medium material graphic printing layer to obtain the substrate-free 3D visual effect graphic product.

[0028] The present invention has the following beneficial effects:

[0029] This invention proposes a method for manufacturing substrate-free 3D visual effect graphic products. The method involves printing graphics on a substrate material pre-coated with an optical medium material graphic printing layer. A curing adhesive composition for forming lenses is then applied to the printed surface of the substrate material or to a pre-fabricated 3D array lens mold. The 3D array lens mold is pressed against the substrate material, thereby pressing and curing the curing adhesive composition to bond it to the optical medium material graphic printing layer. Finally, the substrate material is peeled off from the optical medium material graphic printing layer, resulting in a substrate-free 3D visual effect graphic product. The product is designed such that the adhesion between the substrate material and the printed optical medium material is less than the adhesion between the curing adhesive composition and the printed optical medium material. This is equivalent to a release treatment between the printed optical medium material and the substrate material, allowing the printed optical medium material bonded to the curing adhesive composition to be completely peeled off from the substrate material. Thus, the printed optical medium material, originally printed on the substrate material, is seamlessly transferred to the curing adhesive composition, eliminating the original substrate material and effectively reducing the overall thickness of the product. Furthermore, the coating thickness of the curing adhesive composition can be controlled between 10-100 micrometers according to process requirements. The resulting 3D visual effect graphic product becomes a very soft and thin film, applicable to various packaging applications, such as as a packaging film for cigarette packaging, achieving a 3D stereoscopic packaging effect.

[0030] In a preferred embodiment, the optical medium material graphic printing layer is a zinc sulfide or silicon oxide medium material vapor-deposited or electroplated on the substrate material. The printing dyne value of the optical medium material graphic printing layer on the substrate material is 38-45, which provides a good release effect between the optical medium material graphic printing layer and the substrate material. The optical medium material graphic printing layer bonded to the curing adhesive composition can be easily and completely peeled off from the substrate material.

[0031] In the preferred embodiment, through the design and coordination of the female mold roller, the smooth mirror roller, and the first and second winding structures, during the pressing process of the strip (including the curing adhesive composition, the optical medium material graphic printing layer, and the substrate material) continuously passing through these two rollers, it is possible to achieve the release treatment of the substrate material by the optical medium material graphic printing layer already attached to the curing adhesive composition on the substrate material simultaneously with the curing adhesive composition after pressing. Through a single pressing process, the formation of the 3D structure of the 3D visual effect graphic product and the release of the substrate material are realized at the same time, simplifying the production process and completing the product manufacturing process efficiently and reliably.

[0032] This invention can easily manufacture ultra-thin 3D visual effect graphic products with full-page or partial array lenses without substrate thickness, fully meeting the various requirements of softness, thinness and fineness of 3D visual effect graphic products in various packaging and printing applications, and achieving mass production at low cost.

[0033] Other beneficial effects of the embodiments of the present invention will be further described below. Attached Figure Description

[0044] See Figure 1 This invention provides a method for manufacturing a substrate-free 3D visual effect graphic product, comprising the following steps:

[0045] S1. Printing graphics on a substrate material pre-coated with an optical medium material graphic printing layer, which may be graphics processed by 3D software.

[0046] S2. Apply a curing adhesive composition for forming a lens to the printed surface of the substrate material on which the graphic is printed;

[0047] S3. Using a prefabricated 3D array lens mold, the curing adhesive composition coated on the substrate material is pressed and cured. The cured adhesive composition is then bonded to the optical medium material graphic printing layer. The adhesion of the substrate material to the optical medium material graphic printing layer is less than the adhesion of the curing adhesive composition to the optical medium material graphic printing layer.

[0048] S4. Peel the substrate material from the optical medium material graphic printing layer to obtain the substrate-free 3D visual effect graphic product.

[0049] See Figure 2 This invention also provides another method for manufacturing substrate-free 3D visual effect graphic products, comprising the following steps:

[0050] T1. Printing graphics on a substrate material pre-coated with an optical medium material graphic printing layer, which may be graphics processed by 3D software.

[0051] T2. Apply a curing adhesive composition for forming the lens onto a prefabricated 3D array lens mold;

[0052] T3. Using a prefabricated 3D array lens mold, the printed surface of the substrate material on which the graphic is printed is pressed and the curing adhesive composition is cured. The cured adhesive composition is bonded to the graphic printing layer of the optical medium material. The adhesion of the substrate material to the graphic printing layer of the optical medium material is less than the adhesion of the curing adhesive composition to the graphic printing layer of the optical medium material.

[0053] T4. Peel the substrate material from the optical medium material graphic printing layer to obtain the substrate-free 3D visual effect graphic product.

[0054] In the method for manufacturing substrate-free 3D visual effect graphic products proposed in this invention, graphics are printed on a substrate material pre-coated with an optical medium material graphic printing layer. A curing adhesive composition for forming lenses is applied to the graphic printing surface of the substrate material or to a pre-fabricated 3D array lens mold. The 3D array lens mold is pressed against the substrate material, thereby pressing and curing the curing adhesive composition to bond it to the optical medium material graphic printing layer. Finally, the substrate material is peeled off from the optical medium material graphic printing layer, thereby obtaining substrate-free 3D visual effect graphics. The product is designed such that the adhesion between the substrate material and the printed optical medium material is less than the adhesion between the curing adhesive composition and the printed optical medium material. This is equivalent to a release treatment between the printed optical medium material and the substrate material, allowing the printed optical medium material bonded to the curing adhesive composition to be completely peeled off from the substrate material. Thus, the printed optical medium material, originally printed on the substrate material, is seamlessly transferred to the curing adhesive composition, eliminating the original substrate material and effectively reducing the overall thickness of the product. Therefore, compared to traditional manufacturing methods, the 3D visual effect graphic product produced by this invention can form a softer and thinner film, which can be applied to various packaging applications, such as as a packaging film for cigarette packaging, achieving a 3D stereoscopic packaging effect.

[0055] In some embodiments, the substrate material may be paper or plastic. However, the invention is not limited to paper or plastic, and may also include other materials suitable for various printing methods.

[0056] In a preferred embodiment, the optical medium material graphic printing layer is a zinc sulfide or silicon oxide medium material that is vapor-deposited or electroplated on the substrate material.

[0057] In some embodiments, the curing adhesive composition may be a UV-curable composition or a thermosetting composition. The UV-curable composition may include acrylic resin and a photosensitizer, and through appropriate proportioning, can achieve a viscosity suitable for lamination and calendering processes, curing immediately upon exposure to UV light. The thermosetting composition may use methyl methacrylate polymer or other plastic particles, which are melted, calendered, and then pressed into a film using cold rollers.

[0058] In a preferred embodiment, the printing dyne value of the optical medium material graphic printing layer on the substrate material is 38-45.

[0059] According to this preferred embodiment, the optical medium material graphic printing layer has a good release effect with the substrate material, and the optical medium material graphic printing layer bonded to the curing adhesive composition can be easily and completely peeled off from the substrate material.

[0060] In a preferred embodiment, the thickness of the optical medium material graphic printing layer is 100-300 nanometers, more preferably 150-250 nanometers, and more preferably 200 nanometers.

[0061] In a preferred embodiment, the thickness of the cured adhesive composition is 10-100 micrometers.

[0062] In some embodiments, the 3D array lens mold is a metal or transparent mold; the 3D array lens mold is a flat plate or roller mold.

[0063] In some embodiments, the 3D array lens mold is a full-size or partial array lens mold, and the substrate-free 3D visual effect graphic product is a substrate-free 3D visual effect graphic product with a full-size or partial array lens. The lens mold can control the lens size, precision, thickness, and local range.

[0064] In some embodiments, the curing and molding of the curing adhesive composition can be carried out using processes such as ultraviolet light curing, heat curing, and compression molding.

[0065] In some embodiments, the array lens formed by the mold is not limited to dot-shaped, columnar, or arbitrary thickness and angle arrangement.

[0066] In some embodiments, the 3D graphic printing plate is a 3D visual effect graphic printing plate created using laser or electron beam. The graphic image under the lens can be created using lenticular software.

[0067] In some embodiments, images and text can be printed on a substrate material pre-coated with an optical media material image printing layer using printing methods not limited to offset printing, gravure printing, letterpress printing, flexographic printing, transfer printing, embossing, and screen printing. The substrate material pre-coated with the optical media material image printing layer can be in sheet or roll form.

[0068] In some embodiments, the method for manufacturing 3D visual effect graphic products with substrate-free array lenses employs a roll-to-roll manufacturing method. After pressing and curing the printed graphics and pre-made full-page or partial 3D array lens roller molds, the rolls are then wound up to obtain substrate-free full-page or partial array lens 3D visual effect graphic products.

[0069] See Figure 5 In a preferred embodiment, the 3D array lens mold includes a female mold roller 4 engraved with a lens shape and a smooth mirror roller 3. After the tape composed of the curing adhesive composition 1, the optical medium material graphic printing layer and the substrate material is pressed together by the female mold roller 4 and the smooth mirror roller 3, the substrate-free 3D visual effect graphic product composed of the curing adhesive composition and the optical medium material graphic printing layer is wound up by the first winding structure 6, while the substrate material is peeled off from the optical medium material graphic printing layer and wound up by the second winding structure 5. Therefore, through the coordinated design of the female mold roller, the smooth mirror roller, and the first and second winding structures, during the continuous pressing process of the strip (including the curing adhesive composition, the optical medium material graphic printing layer, and the substrate material) through these two rollers, it is possible to simultaneously achieve the release treatment of the optical medium material graphic printing layer already attached to the curing adhesive composition onto the substrate material while the curing adhesive composition is being pressed on the rollers. Through a single pressing process, the formation of the 3D structure of the 3D visual effect graphic product and the release of the substrate material are simultaneously achieved, simplifying the production process and efficiently and reliably completing the product manufacturing process. In this embodiment, the smooth mirror roller 3 can also be replaced by a flat template.
