Embodiment 1

[0054] Embodiment 1, anti-counterfeiting paper with cicada watermark

[0055] 1. Design contrast watermark

[0056] Use the cicada's wings as a high-gloss multi-layer watermark pattern, and the rest of the cicada as a regular watermark pattern.

[0057] 1. Cicada regular watermark

[0058] 1) Save the pattern of the cicada to the computer in PSD format by scanning, and use PHOTOSHOP software to adjust the pattern (patterns other than the wings of the cicada), so that the fine structure of the pattern can be summarized;

Abstract

The present invention relates to an anti-counterfeiting paper with a contracting watermark and a production method thereof. The method includes the following steps: (1) a regular watermark file and a glazed watermark file are made in computer software; (2) a glazed watermark substrate is put in a computerized laser engraver, and the glazed watermark file is imported to carry out cutting; (3) a regular watermark engraving is engraved according to the regular watermark file, and a corresponding position for a glazed watermark is reserved on the regular watermark engraving; (4) the regular watermark engraving is pressed in a metal mesh, a corresponding position for the glazed watermark is formed in the metal mesh, and the cut glazed watermark substrate is welded at the corresponding position in the metal mesh, so that a mesh cage is produced; (5) the mesh cage is hoisted to a paper machine to carry out paper making, so that the anti-counterfeiting paper with the contracting watermark is produced. The anti-counterfeiting paper is produced according to the method, the contracting watermark is characterized by clear patterns, distinct brightness contrast, etc., and as the visual effect is enhanced, the anti-counterfeiting effect of the anti-counterfeiting paper with the contracting watermark is greatly improved as well.

Description

technical field [0001] The invention belongs to the field of anti-counterfeit paper manufacture, relates to an anti-counterfeit paper with contrasting watermarks and a manufacturing method thereof, in particular to an anti-counterfeiting paper with contrasting watermarks combining conventional watermarks and high-gloss watermarks and a manufacturing method thereof. Background technique [0002] The conventional watermark forming technology mainly relies on the ups and downs of the screen surface to represent different levels of the watermark. During papermaking, the pulp fibers are accumulated on the watermark net, and a matching negative pattern is molded on the wet paper page, so that the fibers of the wet paper page form regular thickness changes. Form multi-level watermark patterns, such as regular white watermark and regular black watermark. Restricted by the production process, this kind of watermark appears as a single-level line effect, which is restricted to a cert...
