Abstract
Systems and methods are provided for inserting hidden information into flush patterns. One embodiment is a system comprising a marking engine that includes multiple printheads, an interface that receives print data for a print job, multiple Raster Image Processors (RIPs), and a print controller. The print controller divides the print data into logical pages, inserts printable information into the logical pages that distinguishes each logical page from other logical pages, and transmits the logical pages to the RIPs for rasterization. The print controller determines that a RIP has completed rasterizing a logical page, transmits the rasterized logical page to a Print Verification System (PVS), directs the printheads of the marking engine to print the rasterized logical page onto a physical page, and directs the printheads of the marking engine to apply a flush pattern onto the physical page at the location of the inserted printable information.
