Description

Technical Field

[0001] The invention relates to the technical field of screen printing and surface pattern processing, in particular to a screen printing mosaic technology. Background Art

[0002] In modern industrial design and manufacturing, the decorative effect of texture is of great significance to the appearance and texture of the product. Especially in the fields of consumer electronics, home decoration, and automotive interior, the texture decoration on the surface of the product not only gives the product a unique aesthetic value, but also enhances user experience and brand recognition. In order to meet the market demand for high-quality surface textures, various texture manufacturing processes are constantly developing, among which silk screen technology and transfer technology are widely used because they can achieve high resolution and fine patterns.

[0003] After searching, it is found that Chinese patent documents disclose a fixed bridge busbar device [application number: 202410176683.X, publication number: CN117863716A], a screen printing device and a printing method thereof, which save the time of scraping and collecting ink and improve the efficiency of screen printing. Although the invention scheme can improve the efficiency, it does not process the background template and still uses the traditional splicing method, which is very different from the scheme mentioned in the present invention in terms of efficiency and effect. Summary of the invention

[0004] In view of the problems existing in the prior art, the object of the present invention is to provide a silk screen printing mosaic technology.

[0005] A silk screen printing mosaic technology, characterized by comprising the following steps: Step 1: Prepare the required shading template according to your needs; Step 2: Make a base plate for splicing, and splice and inlay the shading template on the base plate to obtain template 1; Step 3: Screen print the template 1 to obtain the template 2; Step 4: Transfer the template 2, and transfer other textures on its surface to obtain the template 3; Step 5: Remove the transfer texture, leaving only the transfer texture in the same position as the silk screen to obtain the finished product.

[0006] Preferably, the shading template on the template one is made of a high temperature resistant material, and the surface is subjected to an anti-oxidation treatment to avoid deformation or corrosion caused by temperature or chemicals during subsequent screen printing and transfer processes.

[0007] The above technical solution effectively solves the problems of deformation and corrosion caused by high temperature or contact with chemical substances in the subsequent screen printing and transfer process. In the traditional screen printing and transfer process, the material is easily heated to cause dimensional changes or structural damage, which in turn affects the pattern accuracy of the finished product; and the use of chemical substances may cause oxidation or corrosion on the template surface, reducing the durability of the template and the clarity of the pattern. Through the application of high temperature resistant materials, the shading template can still maintain its structural stability in the high temperature environment of screen printing and transfer, and will not deform due to temperature fluctuations, thus ensuring the precise alignment of the pattern.

[0008] Preferably, the screen printing process in step 3 uses a high-precision screen printing process and cooperates with an optical alignment system to ensure that the screen printing pattern is accurately aligned with the background template pattern. During screen printing, UV curable ink or thermal curing ink is used, and the line width and spacing of the screen printing pattern are controlled within 0.05 mm, thereby forming a high-resolution texture pattern on the second template.

[0009] Through the above technical solution, UV curing ink or heat curing ink can be quickly fixed during the curing process, ensuring the clarity of the pattern edge and improving production efficiency. UV curing ink quickly cures under ultraviolet light, which can improve the adhesion of the ink and increase the durability and wear resistance of the finished product; while heat curing ink cures at high temperature, providing better pattern stability. The use of these inks ensures the stability of the silk screen pattern during transfer and subsequent processing, and is not easily deformed or faded by the external environment.

[0010] Preferably, the transfer in step 4 is performed by thermal transfer, the transfer temperature is controlled between 180 and 220 degrees Celsius, the transfer pressure is controlled between 0.3 and 0.5 MPa, and the transfer time is 3 to 5 seconds to ensure that the texture pattern is completely and evenly attached to the template 2.

[0011] Through the above technical solution, the texture pattern can be attached evenly and completely on the second template, ensuring the high quality of the finished product in terms of texture fineness, color vividness and adhesion firmness. At the same time, the stability and repeatability of the process also significantly improve the controllability of the production process, reduce the scrap rate, and reduce the rework cost caused by transfer defects.

[0012] Preferably, the removal process of the transferred texture is performed by a solvent selective removal method, using a specific chemical solvent to dissolve and remove only the portion of the transferred texture that does not overlap with the screen printing position to avoid damaging the retained texture.

[0013] Through the above technical solution, the texture effect of the finished product is ensured to be accurate and clear, the product quality is effectively improved, and the layers of the multi-layer texture effect are ensured to be clear. The solvent selective removal method not only improves production efficiency and consistency of finished products, but also reduces losses in the production process, and has good economic benefits and sustainability.

[0014] Preferably, the transfer texture is removed in step 5 by a selective adhesion stripping process, where a layer of selective adhesive is first coated on the surface of template two so that the adhesive adheres only to the transfer textures that do not need to be retained, and then these transfer textures are removed from template two by a stripping film, ensuring that only the transfer texture area corresponding to the silk-screen printing position is retained, thereby obtaining a finished product with a clear texture and a precisely matched pattern.

[0015] The above technical solution avoids the problems of misdissolution and pattern edge damage that may occur in traditional chemical removal methods. Due to the selective effect of the adhesive, the peeling area can be accurately controlled to ensure the alignment accuracy of the silk screen and transfer textures, which not only retains the clear texture boundaries, but also avoids the loss of pattern details, thus improving the overall quality of the finished product.

[0016] Preferably, a transparent protective coating is applied to the surface of the finished product, the coating thickness is 10 to 20 microns, and it has wear resistance, UV resistance and moisture resistance to improve the durability and appearance stability of the finished product.

[0017] Through the above technical solution, the finished product is not only more beautiful and glossy in appearance, but also can maintain its texture clarity and color stability under various environmental conditions. This protective layer design greatly improves the overall quality of the finished product and meets the user's high standards for product durability and appearance durability.

[0018] Preferably, during the transfer process, the silk-screen pattern and the transfer texture pattern can be superimposed in multiple layers to form a combination of layers with different transparencies, colors and texture effects, so as to obtain gradient, three-dimensional and glossy effects at different angles, so that the finished product has richer visual depth and dynamic change effects.

[0019] Through the above technical solution, the application of this multi-layer superposition technology makes the texture effect on the surface of the finished product richer and more diverse, breaking through the limitations of traditional single texture and giving the finished product higher design flexibility and uniqueness. This design not only enhances the ornamental value of the finished product, but also enhances the texture of the product. It is suitable for high-end consumer goods, art decorations, and electronic equipment with design and brand characteristics.

[0020] Compared with the prior art, the present invention has the following advantages: 1. The silk screen printing pattern stitching technology adopts the whole plate silk screen printing splicing technology, so that the size of the background pattern template and the subsequent silk screen printing process is completely consistent, ensuring the high-precision alignment of the pattern. This not only ensures the continuity and integrity of the silk screen texture, but also avoids the error problem caused by size mismatch in traditional processes, and improves the precision and quality of the finished product.

[0021] 2. The silk-screen mosaic technology can directly apply the original design to the silk-screen film or screen production, avoiding the steps of copying and manual adjustment in traditional processes. This method greatly simplifies the process flow, shortens the production cycle, reduces labor and material costs, improves production efficiency, and makes the overall cost more competitive.

[0022] 3. The silk screen printing pattern technology adopts precise splicing and stripping technology. This patent achieves a height step of only a few microns and no touch on the surface, making the surface of the finished product smooth and without protrusions. In addition, there are no white spots in the stripping process, ensuring that the surface effect of the finished product is more uniform and delicate, improving the appearance of the product and the user's tactile experience.

[0025] Example 1: Production using silk screen printing technology Step 1: Prepare the required shading template according to your needs; Step 2: Make a base plate for splicing, and splice and inlay the shading template on the base plate to obtain template 1; Step 3: Screen print the template 1 to obtain the template 2; Step 4: Transfer the template 2, and transfer other textures on its surface to obtain the template 3; Step 5: Remove the transfer texture, leaving only the transfer texture in the same position as the silk screen to obtain the finished product.

[0026] Example 1 step flow chart reference Figure 2 .

[0027] Example 2: Traditional silk screen printing technology Step 1: Prepare the required shading template according to your needs; Step 2: Assemble the shading template into the middle piece and transfer it; Step 3: Assemble the transferred middle pieces into a large board; Step 4: Transfer the large plate to obtain template 1; Step 5: Screen print the template 1 to obtain the template 2; Step 6: Transfer the template 2, and transfer other textures on its surface to obtain the template 2; Step 7: Remove the transfer texture, leaving only the transfer texture in the same position as the silk screen to obtain the finished product.

[0028] Example 2 step flow chart reference Figure 3 .

[0029] Comparing the products of Example 1 with those of Example 2, it can be found that the product of Example 2 has the following disadvantages: 1. The more inlays there are, the worse the position and size accuracy will be, and it will be difficult to keep the size consistent with the subsequent screen printing process. When the number of inlaid textures increases, the overall dimensional accuracy may decrease, resulting in position deviation. It is difficult to maintain completely consistent dimensions with the subsequent silk-screen printing process, thus affecting the alignment accuracy and overall consistency of the finished product.

[0030] 2. The screen printing size needs to be copied and confirmed repeatedly, which has a long production cycle and high cost. This process requires multiple transcriptions and size confirmations during the production process to ensure accurate matching with subsequent silk-screen dimensions. The repeated adjustment and confirmation process results in a long production cycle, increased labor costs and material loss, and a high overall production cost.

[0031] 3. The inlay height steps are obvious and tactile, and white spots are prone to appear The high and low steps after inlay are obvious, which makes the surface of the finished product not smooth enough to touch. At the same time, white spots may appear during the development process, which affects the surface aesthetics of the finished product, reduces the quality of the product and the user's visual experience.
