The method involves printing a part (IMG1) of pattern i.e. guilloche pattern, on a layer by offset printing process, and positioning a printing device with respect to a secure document by using reference points printed during the printed process and detected by the device. Another part (IMG2) of pattern is printed on another layer by using a laser printing process, where the latter part of the pattern does not completely cover the former part of the pattern. Authenticity of the document is determined by verifying relative positioning of the parts of the pattern. Independent claims are also included for the following: (1) a system for manufacturing a secure document (2) a method for verifying authenticity of secure document.
