The repeatability of manufacturing process is one of the prerequisite aspects in printed electronics. Particularly, the requirement for the positioning accuracy becomes severe as the miniaturization of printed traces develops, patterning area enlarges, and potential applications widen. Therefore, a measure to quantify the effect of various processing parameters on the global registration error of printed patterns is highly important. In this study, the effect of typical processing parameters appeared in a roll-to-sheet, high-resolution printing (reverse offset printing) including synchronization mismatch, tilting of the roll, unevenness of substrate, were systematically investigated. A fitting model on the basis of Spread polynomials successfully decomposed complicated geometrical distortions into basic components such as scale, skew, rotation, trapezoid, and quadratic warping. The relationship between geometrical distortions and processing parameters was summarized.

卷对页反向平版印刷中通过Spread多项式模型分解图案变形

制造过程的可重复性是印刷电子产品的前提条件之一。特别地，随着打印迹线的小型化的发展，图案化区域的扩大以及潜在应用的扩大，对定位精度的要求变得严格。因此，量化各种处理参数对印刷图案的整体配准误差的影响的措施非常重要。在这项研究中，典型工艺参数的影响出现在卷对纸的情况下，系统地研究了包括同步失配，卷倾斜，基材不平整在内的高分辨率打印（反向胶版印刷）。基于Spread多项式的拟合模型成功地将复杂的几何变形分解为基本成分，例如比例，偏斜，旋转，梯形和二次翘曲。总结了几何变形与加工参数之间的关系。
