    • 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.
    • 印刷机包括基材和至少一个具有至少两个能够相对于基底移动的材料沉积通道的打印头,其中打印头安装在允许打印头围绕垂直于基底的轴旋转和平移的平台上 在垂直于打印方向的方向上,并且其中在每个打印条带期间,改变打印头的旋转角度和平移值,以便在垂直于从打印方向沉积的材料的打印方向垂直的方向上改变间距和横向位置 不同沉积通道; 以及为给定的衬底失真图案计算所需的旋转角度和平移值的算法。
