Problems solved by technology

Such a forming material (for example, ink, resin, etc.) that forms a concave-convex pattern on the surface of a pattern-forming base material by coating or the like is usually in a liquid state or a heat-softened state, so the concave-convex pattern is formed by coating or the like The initial state of the molding material formed on the surface of the pattern-forming substrate (the state in which the desired concave-convex pattern can be formed) cannot be maintained, and not only the desired concave-convex pattern may not be formed, but also the reproducibility may be poor. Difference
It goes without saying that this method is not suitable for forming concave-convex patterns with large fluctuations
③ Using hologram technology to paste the printed concave-convex pattern on the surface of the substrate for pattern formation. This technology not only has the defects of low fidelity, but also has the defects of short service life and easy damage

Abstract

The invention discloses a method for printing stereo concave-convex patterns and a product acquired by the method. The method is a flexible intaglio direct printing technique and includes firstly, using laser to engrave concave-convex patterns needed to be printed onto a flexible printing plate of a printing roller; secondly, filling paint or printing ink into an engraved groove; thirdly, adjusting the printing roller to completely and directly extrude the paint or printing ink filled in the groove of the flexible printing plate onto a substrate surface; and fourthly, drying. Evidently stereo, complex, diversified and vivid concave-convex patterns can be formed on substrate surfaces of articles such as floors, ceramic tiles, glass products, furniture and the like by using simple printing technique, products with colorless, single-colored or multicolor three-dimensional concave-convex patterns can be obtained, the protruding thickness of the stereo multicolor printed concave-convex patterns can reach 25-3000 micrometers, aesthetic appreciation and ornamental requirements of people can be met, and the printing cost is low.

Description

technical field [0001] The invention relates to a printing technology, more specifically, to a method for printing a three-dimensional concave-convex pattern on the surface of a substrate and the obtained product. Background technique [0002] At present, the methods for forming concave-convex patterns on the surface of the substrate are usually the following: ① Using gravure transfer printing technology, that is, the ink in the ink tank inks the gravure roller on the hard surface, and the scraper scrapes off the surface of the gravure roller. The ink outside the groove and the ink in the groove on the surface of the gravure roller are directly transferred to the surface of the substrate under the pressure of the embossing roller on the soft surface. Since the surface of the gravure roll is a hard roll, usually a steel roll, it is difficult to engrave fine and complex patterns on the surface, and the depth of the engraved groove is limited. Therefore, the concave-convex patt...
