Patent ID: 7766447

Claim:
A banding adjustment method for an ink jet imaging device having a plurality of printheads, the method comprising: controlling each printhead in a plurality of printheads in an inkjet imaging device to print onto a receiving surface at most one section in a test band, the printed sections that comprise each test band extend in a direction transverse to a path of the receiving surface during the printing of the test bands; selectively adjusting a drop mass for ink drops generated by at least one printhead in the plurality of printheads between a default drop mass and an adjusted drop mass to print at least one section of at least one test band in the plurality of test bands with ink drops having a drop mass different than the default drop mass; and prompting a user to select one of the test bands in the plurality of test bands or to rank at least one of the test bands in the plurality of test bands; the selective adjustment of the drop mass further comprising: selectively adjusting a driving signal for each ink jet nozzle of a printhead between a default voltage level and an adjustment voltage level to generate the default drop mass and the adjusted drop mass, respectively; storing a voltage level of each driving signal used by each printhead that printed a section of the selected test band as a new default voltage level for each printhead in the plurality of printheads that printed a section of the selected test band.
