Abstract
A printing machine includes a substrate and at least one printhead with at least two material deposition channels which are movable with respect to the substrate, wherein the printhead is mounted on a stage which allows rotation of the printhead around an axis perpendicular to the substrate and translation in a direction perpendicular to the print direction, and wherein during each print swath, the rotation angle and translation values of the printhead are varied in order to change the pitch and the lateral position in the direction perpendicular to the print direction of material deposited from the different deposition channels; and an algorithm which computes the required rotation angles and translation values for a given pattern of substrate distortion.
