The Technical Implementation of Digital Watermarking Technology in Printing Anti Counterfeiting [Buke Printing]

Different digital watermarking technology anti-counterfeiting design schemes have different specific implementation processes. For example, the implementation process of digital watermarking technology using images in printed materials as carriers is:

① Make the image to be printed and embed watermark information into the image using corresponding specialized software (the original image and the watermarked image are visually indistinguishable and almost identical in appearance),

② Output images, plate printing, and obtain the final digital watermark printed product,

③ Scanning processing. Scan the images in printed materials into a computer and perform correction, denoising, and other processing on the scanned images,

④ Extracting watermarks for detection, using extraction software to detect watermark information, and identifying the authenticity of printed materials based on the extracted watermark information. For counterfeiters, this method is difficult to forge because the hidden information cannot be seen. They do not know the method used by the watermark to travel, nor do they know what the information in the plate is. They can only imitate the content of the printed materials that can be seen, and cannot imitate and hide the hidden information, thus achieving anti-counterfeiting function.
