In a digital imaging system including an array of imaging devices that image a substrate in a lateral series of adjacent longitudinal swaths, methods and apparatus for correcting device offset and hiding between regions imaged by adjacent devices. Along the direction of imaging (i.e., the dimension along which the imaging device(s) and the substrate move relative to one another during an imaging pass), adjustments take the form of compensating increases or decreases to the normal intervals between discharges to adjacent image points. Transverse to the direction of imaging, the invention compensates for imprecise device orientation and "seam" artifacts by, first, commencing imaging with the device having the greatest offset from proper orientation, and second, as a fine adjustment, repeating at least one imaging swath to produce intentional transverse overlap between adjacent swaths. <IMAGE> |
