Interpreting plot results
The three plots are all printed using Photo Black ink in 6-pass print mode (even on Gloss paper) and
should should each be similar. The white/lightest band of must be within the center ±1 area for a PASS
result. This should be true for all three plots or the printer will have differential banding (a difference of
advance between the left and right). There is a 3-inch white band before the plots to ensure there is no
platen noise causing advance errors while the media is covering the platen.
Example acceptable plot
The following illustration shows an example of a PASS plot.
