1. Grids The grids are in inches and millimeters. They are labeled 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.
