Problems solved by technology

However, this technology still has certain limitations: the layout of characters has great regularity, and its direction and size are fixed; complex Chinese characters cannot be used as elements of hanging nets, because the outline of Chinese characters is more complicated, and the extracted outline possibly multi-connected regions

Embodiment Construction

[0038] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0039] Figure 7 It is given an image that needs to be hanged artistically, and the butterfly image is selected as the original image here. The hanging net element in this example is the English letter "S", and the result of generating a set of hanging net shading objects through matrix arrangement is as follows image 3 as shown, Figure 5 yes image 3 A zoomed-in view of a part of the netting texture object shown. Align the hanging net shading object and the image after the orthogonal dense arrangement, specify the range of character line thickness change, and then execute the program of image printmaking. For the specific implementation method of image printmaking, please refer to the document "Using 3D Vector Lines to Realize Printmaking Design" ( Qi Wenfa et al., Journal of Computer-Aided Design and Graphics, 2004). After executing the imag...

Abstract

The present invention relates to random artistic screen printing method and belongs to the field of plate-making anti-fake printing technology. The present invention has improved plate grain designing elements, designed line pattern with even high randomness and capability of using any character as screen printing element. The method of the present invention has raised randomness of artistic screen printing, beautiful pattern, increased information complexity and thus raised anti-fake effect.

Description

technical field [0001] The invention belongs to the technical field of plate-making anti-counterfeiting printing, relates to a security shading anti-counterfeiting design technology, and in particular relates to a random artistic hanging net method. Background technique [0002] The current anti-counterfeiting technology is mainly divided into three categories: special material anti-counterfeiting, special process printing anti-counterfeiting and plate making anti-counterfeiting. Different anti-counterfeiting technologies have played a certain role in anti-counterfeiting within a certain range and to a certain extent, but there is no doubt that the cost of the product will increase significantly. As one of the plate-making anti-counterfeiting technologies, security shading anti-counterfeiting technology is one of the most important technologies in anti-counterfeiting printing. Compared with other anti-counterfeiting technologies, it mainly has the advantages of low cost, goo...
