Hi Babak,At which step did you first see some density above paper white on you step wedge print when printing with the original step wedge?And did decrease the Ink Levels before making the decrease to 30%? If so, at which step did you first see some density above paper white?You definitely need to decrease the ink levels more, and I believe another decrease to -40% from the orginal values would be about right.In any event, sounds like you are making good progress.Sandy
