Embodiment

[0039] (1) Make black and white pictures: In photoshop software, create file 1: a file with a size of 20cm×20cm and a resolution of 72ppi. Design and make your own 6 hidden pictures that fit the size of the canvas. The effect is as figure 1 As shown in the 6 pictures.

[0040] (2) Make a black and white grating film: In the software, create a new file 2: a grayscale image with a size of 20cm×20cm and a resolution of 72ppi. Enlarge the picture by 10 times, select the rectangle marquee in the toolbar to draw a long rectangle with a width of 10 pixels, the color of "Edit-Fill" is black, hold down ctrl+c on the keyboard, ctrl+v to copy, and move The horizontal distance between the copied rectangle and the original rectangle is 2 pixels, select the two rectangles to copy and move, and finally form a black and white raster sheet. The effect is as figure 2 shown.

[0041] (3) Frame interpolation algorithm: use the properties of the grating sheet to calculate the number of inter...

Abstract

The invention discloses a manufacturing method of dynamic Moire patterns for frame insertion and anti-counterfeiting in printing. According to the method, a white and black grating sheet is designed, the frame insertion number n is worked out based on the characters of the grating sheet, n hidden black and white pictures are distributed at different positions of the grating sheet, grating processing is carried out on the n pictures sequentially, and then the n pictures are combined into a composite graph; and another grating sheet the same with the former grating sheet serves as a decoding grating sheet, the composite graph and the decoding grating sheet are placed in the same position, and the decoding grating sheet is moved at a uniform speed in the horizontal direction, so that a dynamic graph with the Moire patterns is obtained. The method provides theoretical bases for the hiding and anti-counterfeiting technology of dynamic Moire graphics and text information, the problem that generation of the dynamic Moire patterns is nonstandard currently is solved, and popularization of the dynamic Moire pattern anti-counterfeiting technology is facilitated.

Description

technical field [0001] The invention belongs to the technical field of dynamic moiré anti-counterfeiting, and in particular relates to a method for making dynamic moiré for printing frame insertion and anti-counterfeiting. Background technique [0002] Moiré fringes inevitably affect the quality of brush products in printing, and it is found that moiré fringes have great advantages in printing anti-counterfeiting. With the advancement of science and technology, there are more and more counterfeit goods, and the application of Moiré anti-counterfeiting technology in printed matter is becoming more and more important. However, the single hidden picture makes the anti-counterfeiting coefficient of the static moiré pattern low. If the dynamic moiré pattern is used for anti-counterfeiting, the anti-counterfeiting performance can be improved, multiple patterns can be hidden, dynamic effects can be added, and special anti-counterfeiting functions can be added. At present, there ar...
