Abstract
A method for printing image data with a printing system having a staggered array of overlapping printheads. Adjacent printheads overlap in the cross-track direction defining an overlap region such that image pixels corresponding to the overlap region can be printed with either first or second printheads. The method includes defining an initial row interval N and an initial position of a transition boundary within the overlap region. N rows of image pixels are then printed wherein image pixels on one side of the transition boundary are printed using the first printhead and image pixels on the other side of the transition boundary are printed using the second printhead. A random process is used to iteratively determine updated row intervals, where the position of the transition boundary is shifted by an increment amount of between one pixel and three pixels for each row interval.
