Preparation method of film
A production method and film technology, which is applied to the photoengraving process, instruments, optics and other directions of the pattern surface, can solve the problems of deviation between the pattern and the sample pattern, affect the process accuracy and the final product texture effect, etc., to achieve clear lines and high authenticity. stability and precision, smooth textured effects

Embodiment 1
[0045] Embodiment 1 is in order to illustrate the manufacture method of cloth grain film;
[0046] Step 1. Cleaning: Wash the cloth sample with three-dimensional pattern and then dry it;
[0047] Step 2. Line scanning: use a probe-type measuring instrument to perform line scanning along one side of the cloth to the other side, and obtain the following figure 1 the graph shown. figure 1 The curve diagram shown in is only the part of the cloth sample, including curve A1 and curve A2, among which, the lowest valley in the curve diagram is used as the benchmark, which is calculated as 0um, the peak height of curve A1 is higher than 100um, and the peak height of curve A2 is lower Therefore, the texture of the template can be mainly 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 represent the difference in texture height, it is necessary to cut ...
Embodiment 2
[0052] Embodiment 2 is in order to illustrate the preparation method of dermatoglyphic film;
[0053] Step 1. Cleaning: Thoroughly clean the skin pattern with alcohol to ensure the surface is clean;
[0054] Step 2. Line scanning: use a roughness profiler (manufactured by Hommel, Germany, model T1000) to scan the surface profile along the middle position of the dermatoglyphic template, and obtain as follows: Figure 4 the graph shown. According to the distribution state of the curve in the graph, the texture fluctuation of the dermatoglyphic sample is analyzed, and it is considered that the height of the texture is between 0um and 50um, and is based on the distribution density of the curve, mainly with 12.5um and 25um as the boundary ( like Figure 4 Center line 1 and line 2), divided into three layers, the curve distribution in the range of 12.5um-25um is the most dense; in order to better reflect the texture fluctuations, three layers of 12.5um, 25um and 37.5um are selecte...
