All inkjets suffer banding to one degree or another. Sometimes the
degree of banding depends on adjustments in the machine, such as
paper advance micro settings. The most obvious artifacts occur when
one or more nozzles are blocked in the head. The degree to which the
native banding of the printer becomes obvious depends also on how
it is being driven (the RIP). If multilevel (size) dots are being
used, the way in which small dots cross over into larger dots affects the
degree of banding. Correlation between the screening of the different
color planes affects banding. The degree to which an image depends on
the dots from one color plane (for instance, black) affects banding.
The RIP setup can therefore be "kind" to the printer, and conceal its
banding as much as possible, or it might tend to highlight the
underlying printer banding behavior.
