Problems solved by technology

[0003] The encrypted paper based on dot-matrix pattern-based fiber-forming paper is produced. However, when manufacturing paper, it is time-consuming and labor-intensive to build paper-making equipment and encryption equipment prototypes. At the same time, it is difficult to guarantee paper quality, and the paper machine process is too Long, hard to actually do for testing small pieces of encrypted paper

Embodiment Construction

[0027] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.

[0028] Taking the code "Shaanxi University of Science and Technology" as an example, the present invention will be further described.

[0029] see figure 1 , a simulation method for embedding digital information on paper, firstly carry out basic paper modeling, select the cuboid command in Unigraphics NX, first perform paper origin positioning, and then carry out dimension design, and then select None for Boolean coefficients. After the basic paper is constructed, create the text "Shaanxi University of Science and Technology". Select the surface for the text type, select the text placement surface as the front of the virtual paper, select the curve on the surface for the position placement method on the surface, remove the reference text, and enter: "Shaanxi Science and Technology University", the anchor position and parameter percentage are de...

Abstract

Provided is a simulation method for paper digitized information embedding, used to solve a virtual modeling problem of existing fiber finished paper encryption paper. Unigraphics NX is used in the simulation method for virtual product modeling of digitized paper, to satisfy design concept of the digitized paper to the largest extent. The method is mainly aimed at simulation for fiber finished paper encryption paper based on bit-mapped images. Through Unigraphics NX, a 3D paper model is firstly formed. Since the bit-mapped image is regular fiber interlacing formed by spiral air flow, or is formed by a magnetic dot-matrix encoding controller acting on magnetic fibers, so encrypted images and characters need to be loaded in paper by an embedding method, and then realization rendering is performed. Encrypted paper would be displayed as a simulation crack image through fiber scanning or magnetic powder covering. In an early stage of information embedding, the method improves paper quality by using simulation performance of software, and time-consuming and effort-consuming construction on a papermaking device and an encryption device model machine in practice is reduced.

Description

technical field [0001] The invention belongs to the technical field of papermaking, in particular to a simulation method for embedding digital information on paper. Background technique [0002] In recent years, with the rapid development of the bill business, some lawbreakers have created counterfeit bills by cloning and altering bills, which not only caused heavy economic losses to the country, but also affected the stability of the financial order. Among the counterfeit bills, ordinary bills (such as tax bills) have become the main counterfeit objects, and the original fluorescent anti-counterfeiting and security thread anti-counterfeiting technologies of ordinary bills are no longer suitable for the identification requirements of current bill management. [0003] The encrypted paper based on the dot-matrix pattern-based fiber into paper is produced. However, in the manufacture of paper, due to the time-consuming and labor-intensive construction of the paper-making equipm...
