Application of Invisible Image Anti-counterfeiting Technology in Packaging

Patent name Invisible image anti-counterfeiting technology Application on packaging Patent applicant Yunnan Qiaotong Packaging & Printing Co., Ltd. Principal applicant Address 657000 Zhaotong District Zhaotong District, Zhaotong City, Yunnan Province invented humanities Jie; Peng Xiang; Zheng Xiaobo Application (patent) No. 200310110988.9 Date 2003.11.17 certification date approval announcement number 1545063 approval announcement date 2004.11.10 specification CD-ROM number D0445 main classification number G06T5/00 classification number G06T5/00 division of the original application number priority item abstracts The present invention relates to packaging anti-counterfeiting technology, The application of the invisible image anti-counterfeiting technology described in the packaging is composed of the following steps: (1) selection of a hierarchy map; (2) selection of images to be invisible; (3) hierarchical images and invisible image preprocessing; (4) invisible image fusion (5) Image merging; (6) Interfering film production; (7) Printing of film and interference film film; (8) Printing a gradation chart containing invisible images on a package, and the invisible image anti-counterfeiting provided by the present invention. Technology can incorporate images that are invisible on any layered map on the original packaging without changing the effect of the original layered image, and does not need to create invisible images Generate a new map, invisible images are invisible to the naked eye, as the figure in the figure, can only be seen with the help of interference plates, each invisible image can only be seen with the supporting interference plate, that is, with a The key to open a lock can effectively prevent others from copying the package. Sovereignty item 1, the application of invisible image anti-counterfeiting technology in packaging, is characterized by the following steps: (1) Selecting a hierarchy diagram: The selected hierarchy diagram may be monochromatic or multi-colored; (2) ), Select the image to be invisible: The invisible image can be text or graphic; (3) Hierarchical image and pre-processing of invisible images: a. Use a special image design software to separate color charts; b. Use special images. The design software proposes that one of the monochrome images be stored as a TIF format image, and the remaining monochromatic images be merged into a hierarchical image again; c. The selected monochrome image and the invisible image are superimposed with the image processing software. After determining the location of the invisible image, close the monochrome hierarchy diagram and save the individual invisible image as a TIF format map; (4) Invisible image fusion: a. Select the monochrome hierarchy and need to be invisible. The TIF format image is processed and merged with the graphic fusion software; b. The specific image processing parameters and the image frequency parameters after the image fusion are set; c. The merged image is exported as a monochrome image; (5) The image combination : Integrate And said step of forming monochrome images (3) in item b merged hierarchy FIG recombined hierarchical view of the original polychromatic image processing software. (6) Interferential chip production: The vector graphics software is used to create numerous in-line solid lines. The parameters of these lines, line spacing, line thickness, and line frequency must be consistent with the parameters of the fused image. (7) Printed film and interference film film: a. The output of the printed film containing an invisible image hierarchy diagram requires output of the network cable to exceed 200L/INCH; b. The output of the interference film film line is consistent with the hierarchical image. (8) Printing: The hierarchical image with invisible images can be printed on the package by conventional printing.
