Abstract
An image to be printed on a surface of a substrate that forms, or will be used in, a personalized security document is generated. The image to be printed is then sliced, divided, separated, etc. into a plurality of separate image portions. Each of the separate image portions is then printed onto the substrate. Together, the separate printed image portions form the desired image on the substrate. Each image portion contains only a portion of any confidential or personal information. Each separate image portion is printed using separate sections of a single print ribbon. Since each image portion is printed using a different section of the print ribbon, each ribbon section contains only a portion of any confidential or personal information. This makes it difficult for someone to obtain the confidential or personal information from just a brief or casual glance at the used print ribbon.
