Description

Technical Field

[0001] The present invention relates to the technical field of imaging film design and manufacturing, and in particular to a method and system for designing an imaging film that presents a 3D grayscale effect. Background Art

[0002] With the continuous development of science and technology, imaging film technology is increasingly used in various fields. This technology can use the special structure and properties of the film to present a variety of imaging effects, such as dynamic effects, suspension effects and three-dimensional effects. These effects not only enrich the visual experience, but also bring more possibilities to product design, advertising, artistic creation and other fields.

[0003] However, in the existing imaging film system, although a variety of imaging effects can be displayed, there are still some shortcomings in color presentation. Specifically, most of the current imaging film designs are presented in a single color or multiple layers of different colors, and the depth (or intensity) of these colors is often kept consistent. This color presentation method limits the ability of imaging films to express complex images and delicate color changes. The main reason is that the filling color and depth of the micro-nano structure are kept consistent. In traditional imaging film designs, micro-nano structures are usually filled with the same color and their depth is also kept consistent. Although this design method can simplify the manufacturing process, it lacks flexibility and variability in color presentation and cannot meet the needs for complex images and delicate color changes.

[0004] Therefore, how to improve the design of imaging films so that they can present richer color levels and grayscale effects has become a problem that needs to be solved urgently. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Embodiment 1

[0046] In order to solve the problem of maintaining a single color and consistent color depth in the existing imaging film design method in terms of color presentation. Figure 1 As shown, an embodiment of the present invention provides a method for designing an imaging film that presents a 3D grayscale effect, the method comprising:

[0047] S1: Use 3D modeling software to build 3D images according to design requirements and output 3D files;

[0048] S2: Read the 3D file, calculate and output the grayscale image file according to the set microlens parameters and calculation format;

[0049] S3: grayscale photolithography is performed on the photolithography material according to the grayscale image file to form a micro-nano structure with varying depths;

[0050] S4: UV embossing and filling with single-color ink to present different depths, or coating to achieve different depths of gloss.

[0051] It can be seen from the above technical scheme that the present invention proposes a method for designing an imaging film that presents a 3D grayscale effect, aiming to solve the problem of single color and consistent depth in the traditional method. The method first uses 3D modeling software to construct the required image and output a 3D file, and then accurately calculates the grayscale image file by reading the file, combining the preset microlens parameters and the calculation format. In this step, different 3D heights are automatically defined as different grayscale values, realizing the accurate definition of the grayscale of each position of the image. Then, grayscale lithography technology is used to form micro-nano structures of varying depths on the photolithographic material according to the grayscale map. This structural change directly determines the grayscale effect of the final image. Finally, through UV embossing and monochrome ink filling or coating treatment, not only a rich sense of depth is presented, but also a difference in glossiness is achieved, thereby perfectly showing the 3D grayscale effect. This scheme not only enhances the layering and expressiveness of the image, but also realizes the leap from monotonous colors to the natural transition of color strength, greatly enriching the design possibilities of imaging films.

[0052] In step S1, a 3D image is constructed according to design requirements using 3D modeling software, and a 3D file is output.

[0053] Specifically, first, use professional 3D modeling software (such as Blender, SolidWorks, 3ds Max, etc.) to build (or import existing) 3D images according to design requirements. Figure 2 As shown. Ensure that the 3D image has clear geometric structure and details to support subsequent grayscale image calculation and 3D effect presentation. Then, export the constructed 3D image to a file format suitable for subsequent processing (such as STL, OBJ, FBX, etc.). According to actual needs, simplify or optimize the 3D image as necessary to reduce the calculation complexity while maintaining the integrity of the visual effect. Finally, ensure that the exported 3D file contains all the necessary geometric information so that it can be accurately read and processed in subsequent steps.

[0054] In step S2, the 3D file is read, and the grayscale image file is calculated and output according to the set microlens parameters and the calculation format, such as Figure 3 As shown, specifically including:

[0055] Read the output 3D file.

[0056] The microlens parameters are set, wherein the microlens parameters include focal length f, refractive index n, arrangement mode and arrangement period T, wherein the arrangement mode includes honeycomb arrangement, square arrangement, etc.

[0057] Set the calculation format, that is, the arrangement format of the microlenses, for example, a square arrangement, the width of the format is W and the height is H, the arrangement period is T, then the number of horizontal coordinates is W / T, and the number of vertical coordinates is H / T.

[0058] The coordinates of each micro-image are calculated according to the integrated imaging algorithm. For example, the grid coordinates in the 3D data are I (x, y, z), and the microlens coordinates are L (x, y). Then the coordinates P (x, y) of the micro-image are calculated as:

[0059] Px=(Ix-Lx) / Iz / n*f;

[0060] Py=(Iy-Ly) / Iz / n*f;

[0061] Among them, Ix, Iy, Iz are the grid coordinates in different directions in the 3D data; Lx, Ly are the microlens coordinates in different directions; Px, Py are the micro-image coordinates in different directions.

[0062] It should be noted here that if the height range is h1-h2, the height range h1-h2 corresponds to the grayscale 0-255.

[0063] Each micro-image is combined into an overall grayscale image T(x, y) = ∑P(x, y). This grayscale image will contain grayscale information for subsequent photolithography processing. Figure 4 This is a screenshot of the calculated partial grayscale image.

[0064] In step S3, grayscale photolithography is performed on the photolithography material according to the grayscale image file calculated above to form a micro-nano structure with varying depths.

[0065] Specifically, first, ensure that the grayscale lithography equipment (photolithography machine) is in good working condition, and adjust the equipment parameters to adapt to the format and size of the grayscale image file. Then, import the calculated grayscale image file into the photolithography machine for lithography processing. During the lithography process, the photolithography machine controls the intensity or exposure time of the laser according to the different grayscale values ​​of the grayscale image, thereby forming microstructures with different depths on the photolithography material (photoresist). After the lithography is completed, post-processing steps such as development and fixing are performed to remove excess photoresist and retain the desired microstructure.

[0066] In step S4, UV embossing is performed and a single-color ink is filled to present different depths, or gloss of different depths is achieved through coating, thereby presenting a 3D grayscale effect.

[0067] Specifically, first, the microstructure on the photoresist is transferred to the imaging film using UV embossing technology. This step usually involves placing the imaging film on top of the photoresist, then applying pressure and curing it with UV light. Then, according to the design requirements, a single-color ink or coating material is selected to fill or coat the imaging film. This step is designed to enhance the 3D grayscale effect, giving the image a different sense of depth and gloss.

[0068] Ink filling: Use precision ink filling equipment to evenly fill single-color ink into the microstructure of the imaging film. The choice of ink should be based on the desired visual effect and durability.

[0069] Coating treatment: If coating is used, a thin layer of metal or non-metal film needs to be coated on the surface of the imaging film. Coating can be achieved by chemical vapor deposition, physical vapor deposition and other methods.

[0070] Finally, whether ink filling or coating treatment is used, a curing step is required to ensure the stability and durability of the material. After curing, necessary cleaning is performed to remove excess ink or coating material.

[0071] Through the detailed implementation of the above steps, an imaging film with a 3D grayscale effect can be successfully designed and produced.
