Concave-convex printing process

The invention discloses a concave-convex printing process, and relates to the technical field of printing. The concave-convex printing technology comprises the following steps that S1, an image-text style is designed according to requirements; s2, manufacturing a flexographic plate through plate making equipment based on the image-text style; s3, pasting a supporting plate on the flexographic plate so as to form a mother set; s4, making cured concave-convex grains on the mother set based on the image-text style; s5, images and texts are printed on the cured concave-convex grains; s6, pressing a bearing sheet at one end of the concave-convex grain of the mother set, and transferring the image-text to the bearing sheet by using a UV transfer printing process; and S7, peeling off the bearing sheet to obtain a finished product. In the step S2, the image-text style comprises a style size and a style thickness, the size of the flexographic plate is determined based on the style size, and the thickness of the flexog
