 only the UV watermarks produced by DBD Druck Bernd Derrant deserve the designation counterfeit-proof copy protection paper - why? Because the UV watermarks we create have several properties combined into one security feature: Watermark light translucent and fluorescent under black light, in addition to natural papers, coated and/or colored papers can also be used. There is another way to top the security level by providing the security papers with sequential fluorescent UV numbering . https://own-watermark.com/copy-protection-paper-real-forgery-proof/ “Copy protection paper” means “ protection against unauthorized copying” where is that?
