Abstract
A paper forming mold, comprising a roller (). A number of through micropores are formed on a wall of the roller (), and one or more patterns and characters of a normal watermark, a white watermark, a windowed security thread, and a paper marker are carved on the wall of the roller (). The paper forming mold has a high reproducibility for an original watermark design draft, improves consistency, clarity, three-dimensionality, detail refinement and richness of the watermark in paper, and thus enhances the anti-counterfeiting function of the watermarked paper; the service life of the paper forming mold is prolonged; and the automation level of paper forming mold manufacturing is improved, and the labor intensity is greatly reduced.
