Problems solved by technology

However, this technology also requires a special mold. The mold forming process is complex, the molding cycle is long, and the mold forming equipment is expensive. In addition, the micro-graphic embossing or printing process in the later stage is also complicated, low in efficiency, and high in equipment costs, resulting in final molding. The high cost of 3D products reduces the possibility of packaging applications

Embodiment 1

[0058] Such as Figure 1-9 Shown, the 3D imaging method of a kind of microstructure optical film of the present invention, this method comprises:

[0059] S10, making a 3D imaging micro-graphic file;

[0060] S20, making the transfer film of the generated 3D imaging micro-image file;

[0061] S30. Transfer the transfer film onto one of the surfaces of the microstructured optical film by means of hot stamping.

[0062] Specifically, a plurality of microlenses 21 are arrayed on the other surface of the microstructured optical film 2 . The design of 3D imaging micro-text is carried out through the relevant parameters of micro-lenses 21 arrayed on the other surface of the micro-structured optical film 2. The micro-text pattern can be text, logo, sign, number, etc., and the micro-text pattern Try to choose strokes and shapes that are relatively simple. Next, the 3D imaging micro-graphic file is made into a transfer film 1, and the transfer film transfer 1 is transferred to one ...

Embodiment 2

[0098] Such as Figure 10-11 As shown, the difference between this embodiment and the previous embodiment is that the way of hot stamping in this embodiment adopts the way of cold stamping, therefore, in this embodiment, the transfer film 1A includes a protective layer 15A, a micro-texture layer 14A, aluminum layer 13A, peeling layer 12A, and substrate layer 11A; protective layer 15A, microtexture layer 14A, aluminum layer 13A, peeling layer 12A, and substrate layer 11A are sequentially stacked from top to bottom. Under the action of UV cold transfer glue, the micro-texture layer 14A is transferred onto the second surface of the micro-structured optical film 2A, and the first surface of the micro-structured optical film 2A is arrayed with micro-lenses 21A.

[0099] In the cold transfer process, the adhesive layer 22A is uniformly coated on the designed position of the second surface of the microstructure optical film 2A by the cold transfer equipment, and then the cold transfe...

Abstract

The invention discloses a method and a device of 3D imaging of a microstructure optical film. The method comprises the following steps that a 3D imaging micro-image-text file is manufactured; transferfilm making is carried out on the generated 3D imaging micro-image-text file; and the transfer film is transferred to one of surfaces of the microstructure optical film in a hot stamping mode. According to the method and the device of the 3D imaging of the microstructure optical film, the 3D imaging micro-image file is made into the transfer film in a holographic imaging mode, moreover, the transfer film is transferred to one of the surfaces of the microstructure optical film in the hot stamping mode, and finally a periodically amplified 3D image effect is formed through the micro lens on theother surface of the microstructure optical film, so that the 3D reproduction of a high-precision micro-image is realized, the complexity of the 3D micro-image forming is reduced, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to an optical film imaging, more specifically to a 3D imaging method and device for a microstructured optical film. Background technique [0002] At present, the demand for microstructured optical films in the packaging market is increasing, and the production of dynamic high-depth 3D images through microstructured optical films has become an object of research and development in the packaging market. At present, there are three main types of micro-text 3D imaging technology: ordinary printing process, nanoimprint lithography (NIL), and micro-contact printing. [0003] Ordinary printing process is to use commonly used offset printing, flexo printing, embossing and other printing processes to realize the printing of micro-graphics, and combine with micro-structured optical film to finally form a 3D image effect. However, when 3D micro-graphic printing is realized, it is limited by the output accuracy of its output equipment and it...
