1. Grids	The grids are in inches and millimeters. They are label with
	letters and numbers so that defects can be described by
	position and by distance between repeats.
2. Color plane registration (CPR) bars	After printing, the box with no extra color in each area on
	each page shows how far off the CPR of that color is. Each
	page has two process direction areas and three scan
	direction areas that are labeled x and y and 1–11. The page
	should be fed by the long edge. Each square from the center
	equals 42 microns.
3. Color ramp patches	Used to detect offset for the OPC or developer in the image
	drum or offset in the fuser.
