Abstract
A system is disclosed. The system includes a print controller including one or more processors to receive print data, rasterize the print data into bitmap data, analyze objects in each page of bitmap data to determine sizes of objects and generate mapping data for each page of bitmap data that maps locations of page bitmap data having same size objects, a print engine to print the bitmap data to a medium and a print verification system to capture one or more images of the medium as print verification data and to detect one or more defects in the print verification data.
