摘要:
A method of printing an image having a graphic security element included therein includes receiving main image data representing a main image, receiving graphic security element data representing a graphic security element to be included in the main image, receiving a request to print the main image, responsive to receiving the request to print the main image, determining particular pixels of the main image data that are to be shifted based on the graphic security element data, and causing a plurality of ink deposits to be deposited on the print medium based on the main image data including causing the position of each of the ink deposits on the print medium that is determined to correspond to shifted pixels to be shifted relative to a normal position that would normally result from the main image data. Also, system that implements the method is provided.
