1. A system comprising:
a print server comprising:
an interface configured to receive a test print job;
a memory configured to store the test print job; and
a print controller configured:
to determine a number of copies of the test print job to print, wherein the number of copies is greater than one,
to subdivide each sheetside image of the test print job into a number of distinct zones corresponding to the number of copies, wherein the number of zones equals the number of copies,
to assign each of the zones of said each sheetside image to a different copy of the test print job, and
for each copy of the test print job, to seed a print defect into each sheetside image of the copy of the test print job, wherein the print defect in each sheetside image is seeded only within a zone assigned to the copy.
