The invention discloses a method for coating an irregular curved surface complex pattern. The method comprises printing surface spraying, jig manufacturing and transferring. According to the method, the limitation of the shape of a material printing surface is broken through, and the effect of presenting the pattern in a spraying and light irradiation mode is achieved; for a single-color pattern, a transferring film for manufacturing each product is omitted, the cost is saved, and the problem that in the water transfer printing technology, positions and patterns lack consistency is solved; a curved-surface shading film is used, so that the requirement for the light source parallelism is greatly reduced, the product technology can be used for a common product, and the production precision and consistency are improved.
Description
Technical field [0001] The invention belongs to the technical field of surface coating, and particularly relates to a coating method for irregular curved surfaces with complex patterns. Background technique [0002] For the irregular surface of the material (non-planar, irregular curved surface), the available methods for decoration of specific positions or specific patterns generally include thermal transfer, cold transfer (water mark transfer), water coating transfer, pad printing, These methods of blocking spraying. For thermal transfer, the principle is to use a vacuum pressure difference, supplemented by a pressing roller, to make the thermal transfer film fully adhere to the printing surface, and to adhere to the printing surface using the hot melt of the ink used. Based on this principle, for the concave surface or the printing surface, there is a relatively steep transition. Since the air between the transfer film and the material cannot be completely sucked away, the tr...
