Abstract
A method of compensating for changes in drop mass of drop emitted by at least one ink jet of an ink jet imaging device is provided. The method comprises identifying a drop placement position on an image receiving member of an ink jet imaging device for at least one ink jet of a print head. The identified drop placement position for the at least one ink jet is compared to a default drop placement position for the at least one ink jet to determine a difference in drop placement position. A drive signal for the at least one ink jet is then adjusted in accordance with the difference in drop placement position.
