Problems solved by technology

[0003] The purpose of the present invention is to provide a method for making an anti-counterfeit pattern by superimposing a fractal graph with a fractal curve, which can overcome the irregularity of the existing fractal pattern drawing method, the high requirements for the professional level of the drawing personnel or pattern designers, and the long design period, etc. Insufficient in the field, it provides a method that allows users to draw complex anti-counterfeiting patterns only through simple operations

Embodiment 1

[0040] The multiple iterative formula is used when drawing the pattern, and the formula is set as: cos(z)-a / z(k)(a=2). Select the "escape time radius method" for the drawing method, select the Julia set for the type; set the complex plane coordinate parameters as (-1.5, -1.5), (1.5, 1.5); set the initial value as: X is 0.32, Y is 0.04, The number of iterations is set to 10, and the index K is set to 2. Then set the color scheme information, select "Theme" in "Color Scheme", set the starting color of the pattern and the conversion formula of the three primary colors R, G, and B. Among them, the initial value of R is 216, and the change item of R is determined by the formula log(x); the initial value of G is 32, and the change item of G is determined by the formula log(log(y*y)); the initial value of B is 125, and the change of B The term is determined by the formula sin(log(d*d)). The gradient step size is 0.5, and finally click the "Drawing" button to get image 3 fractal p...

Embodiment 2

[0042] In the fractal curve production panel, set the fractal curve to "crown", the number of iterations to 5, and the line width to 3. Click "Start mouse selection", drag the mouse to determine the start point and end point, and draw a fractal curve. Drag and drop the mouse twice in different directions to get Figure 4 fractal curve.

Embodiment 3

[0044] In design management, import image 3 and Figure 4 . choose image 3 as a background image, Figure 4 As the foreground image, the masking value of R, G, and B colors is set to 100%, and the transparency is set to 40%. Click Synthesize to generate Figure 5 corresponding pattern shape. Figure 5 That is a complete pattern of the present invention.

Abstract

The invention discloses an anti-counterfeiting pattern manufacturing method using a fractal pattern to overlap a fractal curve. The pattern manufacturing is finished by two methods, namely the manufacturing of the fractal pattern and the manufacturing of a pattern of the fractal curve. The method comprises the concrete steps of: (1) the manufacturing of the fractal pattern, which comprises the steps of: adopting a mathematical formula to set parameter information and color matching information in a computer drawing panel, and drawing the fractal pattern in the computer drawing panel; (2) the manufacturing of the pattern of the fractal curve, which comprises the steps of: 1, setting an alphabet V, an initial axiom omega and a generative rule P in a computer fractal curve drawing panel; and2, then setting initial point coordinates (x, y) in the drawing panel in the step 1 to establish the circulation of iteration number n and execute the iteration number from 1 to n, and searching eachcharacter in a new character string F produced in the step 3 in sequence; and (3) performing graph overlapping on the fractal pattern manufactured in the step (1) and the pattern of the fractal curvemanufactured in the step (2) in the computer drawing panel to obtain an anti-counterfeiting pattern. The method can resist reprography in combination with the embedded fractal curve and special ink printing technology to realize the double anti-counterfeiting function.

Description

technical field [0001] The invention relates to pattern making, in particular to a method for making fractal anti-counterfeiting patterns. Background technique [0002] At present, the known fractal pattern drawing method is to set an iterative formula by the designer, program the drawing method, and set an appropriate color scheme in it, and finally generate the pattern. However, when the generated pattern is used for anti-counterfeiting pattern design, its ability to resist copying is limited. The anti-counterfeit pattern with fractal graph superimposed on fractal curve produced by the present invention, combined with complex fractal pattern and special ink printing technology, not only cannot be repaired by other graphics and image processing systems, but also can resist copying and has double anti-counterfeiting functions. Contents of the invention [0003] The purpose of the present invention is to provide a method for making an anti-counterfeit pattern by superimpos...
