A printing system for printing both secure value documents and non-secure documents while ensuring that fraudulent copies of secure value documents printed by the printing system can be detected is provided. The printing system determines if the source is a secure or non-secure source. If the source of the image is a secure source, it will print the image, including any graphic security features. If the source is a non-secure source, before printing the image a filter is applied to the image data to remove any graphic security features included in the received image and/or the printing system will not add any graphic security features to the received image to ensure that the printed image will not contain any copy detection graphic security features. |
