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.
