    Run a dry solid, no water if band is gone then damping unit is the culprit. If band remains check ink rollers

    Make sure all ink forms are not oscillating,if they are moving side to side put shims on you should not be able to wiggle back and forth, you have to go one step at a time ,process of elimination

    Then you need to concentrate on the ink rollers make sure they are in good shape , correct stripes, no bouncing,or moving side to side _you can also try localize problem by backing off one form at a time and running some sheets
