Embodiment Construction

[0020] Anti-counterfeiting cards are made of plastic lenticular sheets, such as figure 1 As shown, the graphic layout of the anti-counterfeiting card includes vertical stripes 1, foreground graphics 2 and background graphics 3 composed of regularly arranged hidden graphic elements.

[0021] An anti-counterfeiting method based on image hiding technology, comprising the steps of:

[0022] The first step is to measure the number of lines of the grating sheet:

[0023] The grating line count is measured using a test strip, which consists of a number of vertical lines (ie test strips) evenly distributed. If testing a 100LPI (line / inch) grating sheet, first make 20 test strips (with 100LPI as the middle number, 10 strips on the left and right, that is, from 99.0LPI to 100.9LPI, the difference between two adjacent test strips is 0.1LPI ) test strips, each test strip is about 20mm high, and the length is equal to the length of the grating sheet.

Abstract

The invention discloses an anti-counterfeiting method based on an image hiding technology. According to the method, a certain pattern element is hidden in a certain background graph, the pattern element is printed on a grating sheet material by creatively utilizing the optical property of the plastic grating sheet material, and post-press finishing is carried out so as to obtain an anti-counterfeiting card. The method can be applied to anti-counterfeiting of credentials, certificates, card products and package box products. The method has the advantages that only design and production staff know the processing process of the hidden image-text in a card, so that the card has a strong anti-counterfeiting function and is difficult to imitate; the card is convenient to use, the hidden image-text can be seen by means of equipment with a clear camera shooting function, so that the method has the advantages of simple identification and low cost, and can be effectively used for anti-counterfeiting in package, certificates, various cards and other fields; and identification of the hidden image-text of the card cannot be influenced by a bent anti-counterfeiting card.

Description

technical field [0001] The invention relates to an anti-counterfeiting method based on image hiding technology. Background technique [0002] In today's fierce market competition, various companies are constantly developing new products and eliminating old products, thus leading the market trend. Many high-quality products and high-end brand products gradually became the leaders and gained a lot of profits. At this time, driven by profit, some criminals began to counterfeit and forge those famous and high-quality products with inferior raw materials, which brought great harm to consumers, enterprises and society. Consumers, enterprises, and society are all calling for new anti-counterfeiting technologies to curb the momentum of "counterfeiting and counterfeiting". Now, there are various anti-counterfeiting technical means on the market, through which consumers and enterprises can identify counterfeit and counterfeit products on the market. [0003] Anti-counterfeiting tec...
