Background technique

Watermark paper (often referred to as floating watermark paper) is an ancient and effective traditional anti-counterfeiting technology. Watermarking is the easiest watermarking method to be recognized by the naked eye. It has been used since its inception and has been developed with the continuous development of related technologies. . Watermark paper is in the forming process of the paper web, using online forming technology, when the paper is just interwoven and still contains a certain amount of moisture, the watermark with engraved texture is used to hydraulically stamp the paper surface, so that the tissue of the wet paper page is dislocated to form various A mark or pattern. Because the thickness of the watermark image and text is different from that of the blank space, the density and light transmittance of the paper are different, so that the backside shows a clear and transparent watermark image and text under the irradiation of ordinary light. After the paper watermark is formed into paper, it will never be strongly deformed due to changes in color, light, and temperature. It is inseparable from the paper page; it is easy to produce on a large scale, and can maintain the quality of the front and rear products under the same production process and equipment conditions. The watermark pattern is relatively consistent; and because the watermark pattern has a concise outline, soft outline, complex process, and is difficult to accurately imitate, it is extremely difficult to copy and has strong anti-counterfeiting characteristics.
