Problems solved by technology

In the production process of the two watermark anti-counterfeiting technologies, there is no organic integration with each other, that is, the multi-level watermark and the white watermark are not fused with each other from the design and engraving, interlaced, and superimposed in an overall image (pattern). No two different watermarking techniques show a complete watermark image

Embodiment 1

[0022] The method for synthesizing an overprint watermark in Embodiment 1 includes the following steps:

[0023] 1), the design of the image (graphic) of the superimposed watermark: use computer design software (such as photoshop) to make such as figure 1 The multi-level watermark image shown is used as the base layer, the white watermark graphic is made on the multi-level watermark image and the two are superimposed, and then the white watermark graphic is copied into a silhouette (projection) graphic body, and the silhouette graphic body The grayscale value is 60%, and the outline of the silhouette graphic is 0.3mm larger than the outline of the white watermark graphic. Incorporate the silhouette graphics body into the multi-level watermark image layer or partially overlap and merge (such as figure 2 As shown), make the silhouette graphic body overlap with the white watermark graphic to make an engraved image draft of the superimposed watermark (such as image 3 shown); ...

example 2

[0029] The method for synthesizing an overprint watermark in this example 2 comprises the following steps:

[0030] 1), the design of the image of the superimposed watermark: use computer design software (such as illustrator) to make such as figure 1 The multi-level watermark image shown is used as the base layer, and the white watermark graphic is made on the multi-level watermark image and the two are superimposed, and then the white watermark graphic is copied into a partial silhouette graphic body, and the grayscale of the silhouette graphic body The value is 50%, the outline of the silhouette figure is 0.3mm greater than the outline of the white watermark figure, and part of the figure body of the silhouette is merged into the multi-level watermark image layer and partially overlapped and merged (such as figure 2 As shown), make part of the silhouette graphic body overlap with the white watermark graphic to synthesize the engraved image draft of the superimposed watermar...

Abstract

A method for synthesizing an overlapped watermarker on the antiforge paper includes such steps as designing the image for the overlapped watermarker by computer and software, transmitting it to automatic carving machine, preparing its carved plate, carving the projected profile of white watermarker, making its die, making the metallic sheet of white watermarker, preparing the screen of overlapped watermarker, making screen cage, installing it in paper making, and making the paper with overlapped watermarker.

Description

Technical field: [0001] The present invention relates to methods of synthesizing watermarks, in particular to methods of synthesizing superimposed watermarks. Background technique: [0002] At present, paper watermark images (patterns) reflect watermarks in multiple layers and single layers. The layers of watermarks reflect the strength of anti-counterfeiting functions of watermark images (patterns). counterfeit. Although the white watermark production process is different from the formation of multi-level and single-level watermarks, the paper watermark reflects the characteristics of the contrast, sharpness and light transmittance of the white watermark pattern, but there are also problems in the application of simple graphics, single layers, The anti-counterfeiting function has a single defect. In view of the limitations of the watermark in the above two aspects, some countries in the world, in order to increase the anti-counterfeiting function, adopt a complementary me...
