Tak wynika z nazwy tego narzędzia.

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.

One specific example of the alignment parameter is rotation (roll) of the print head. As used herein, the term “print head rotation” refers to the rotation of the print head in the clockwise or counterclockwise direction about the normal axis (ie, the Z axis) of the image receiving surface.
