Problems solved by technology

[0005] However, the existing production method is manual operation and can only obtain one layer of pattern and output a piece of film, and the other layer patterns are mainly obtained by modifying the vector image of the first film made before through subjective plane processing, so the final There is a large degree of deviation between the obtained pattern and the sample pattern, which affects the accuracy of the later process and the texture effect of the final product

Embodiment 1

[0045] Step 1. Cleaning: wash and dry the fabric sample with three-dimensional pattern;

[0046] Step 2. Line scanning: use a probe-type measuring instrument to perform line scanning along one side of the fabric to the other side, and obtain the following: figure 1 The graph shown. figure 1 The curve shown in is only part of the fabric sample, including curve A1 and curve A2, where the lowest valley in the curve is used as a reference, counted as 0um, the peak height of curve A1 is higher than 100um, and the peak height of curve A2 is low Therefore, the texture of the template can be divided into two levels, below 100um and above 100um. According to the line scan data, it is necessary to perform layered cutting within the height range of 0-150um. In order to better express the difference in texture height, it is necessary to cut one layer above and below 100um; confirm the cutting according to the line scan results Cutting standard, cutting in two layers, the cutting height ...

Embodiment 2

[0052] Step 1. Cleaning: Thoroughly clean the skin texture sample with alcohol to ensure the cleanliness of the surface;

[0053] Step 2. Line scanning: Use a roughness profiler (produced by Hommel, Germany, model T1000) to scan the surface profile along the middle position of the skin texture sample, and get the following: Figure 4 The graph shown. According to the distribution state of the curves in the graph, the texture fluctuation of the dermatoglyph sample is analyzed, and it is considered that the height range of the texture is between 0um-50um, and based on the distribution density of the curve, it is mainly bounded by 12.5um and 25um ( like Figure 4 Center line 1 and line 2), which are divided into three levels, and the curve distribution in the range of 12.5um-25um is the most dense; in order to better reflect the texture undulation, three layers of 12.5um, 25um and 37.5um are selected as the cutting standard ( Preferably, 10um, 20um, and 40um can also be selecte...

Abstract

The invention provides a preparation method of a film. The preparation method comprises the following steps of 1, a line scanning process comprising carrying out scanning by line scanning equipment along the surface of a sample plate having three-dimensional lines to obtain a curve graph, and determining a layered cutting standard according to a curve distribution state of the curve graph, 2, a three-dimensional scanning process comprising carrying out scanning of the sample plate by three-dimensional scanning equipment to obtain three-dimensional data, and constructing a three-dimensional model of the sample plate according to the three-dimensional data, 3, a pattern cutting process comprising cutting the three-dimensional model obtained by the step 2 according to the layered cutting standard determined by the step 1 to obtain film patterns of different layers, and 4, a film output process comprising outputting the film patterns to obtain a corresponding film. Through the preparation method, a multi-layer film can be obtained. The multi-layer film has the advantages of smooth texture and clear lines. The preparation method has simple processes, avoids manual operation, and has strong operability.

Description

technical field [0001] The invention relates to the field of film production, more specifically, to a method for producing a three-dimensional pattern film. Background technique [0002] With the advancement of science and technology and the improvement of people's living standards, the application of automobiles and electronic equipment is becoming more and more common, and the beauty and feel of these consumer products are also more and more people's attention and attention. Many people like natural textures such as leather grain, wood grain, cloth grain, etc. These natural textures are not flat in space, showing a three-dimensional effect, and have a good appearance and touch. It is widely used in design. [0003] Take the interior parts with leather texture effect in vehicles as an example. At present, in order to pursue the high-grade and comfortable interior of automobiles, leather materials are mostly used in vehicle interiors. However, due to the high price of leath...
