The invention relates to a novel embossing roller manufacturing process. The manufacturing process comprises the following process operation steps: S1, sampling by laser scanning; S2, carrying out pattern processing on scanned patterns by a computer to generate a 3D seamless spliced file; S3, carrying out digital processing on the 3D file to enable the 3D file to be used for laser engraving; S4, selecting rubber capable of being engraved by laser, and engraving and reducing the patterns to the surface of the rubber; S5, casting liquid silica gel on the surface of an engraved rubber mold, drying and curing, and reducing the rubber surface patterns to the surface of the silica gel; and S6, removing a silicon gel sleeve, and sleeving the surface of a steel roller with the silicon gel sleeve for embossing operation. According to the novel embossing roller manufacturing process, the silicon gel sleeve is arranged on the surface of the steel roller in a sleeving mode to be used for carryingout embossing process treatment, so that the grains on the surface of a pressed object achieve a series of effects of matting, clear pattern layer, no seam, soft pattern edge transition and the like.An embossing roller manufactured by the process is lower than a prior embossing roller in manufacturing cost, and the grains are adjusted conveniently.
