柔性版印刷涉及油墨印模与基底的高速接触，对于以新格式的电子产品的可扩展制造越来越感兴趣。然而，柔性版印刷的适应更薄，更精细的功能，通常需要印刷电子产品需要更好的理解冲压基板接触力学。在这里，我们提出了一种台式板对卷（P2 R）印刷装置，其使得能够以模仿工业印刷的半连续格式研究柔性版印刷。特别是，我们调整机器的规格，以使用纳米多孔邮票，已被证明能够柔版印刷微米级线宽的油墨功能。用纳米多孔印模印刷需要精确控制印模-基底接触力（2-250 mN）和消除界面处的剪切力等;这些是使用柔性支撑的基底并通过系统的协调旋转-线性运动来实现的。我们详细介绍了P2 R机器的设计和评估，并演示了高分辨率特征的打印（
Flexographic printing, which involves high-speed contact of an inked stamp against a substrate, is of increasing interest for scalable manufacturing of electronics in new formats. However, the adaptation of flexography to thinner, finer features which are generally required for printed electronics requires improved understanding of stamp-substrate contact mechanics. Here, we present a desktop plate-to-roll (P2R) printing apparatus which enables the study of flexographic printing in a semi-continuous format that mimics industrial printing. In particular, we tailor the specifications of the machine to use nanoporous stamps which have been shown to enable flexographic printing of ultrathin ink features with micron-scale linewidth. Printing with nanoporous stamps requires precise control of stamp-substrate contact force (2-250 mN) and elimination of shear force at the interface among others; these are accomplished using a flexure-supported substrate, and by coordinated rotary-linear motion of the system. We detail the design and evaluation of the P2R machine and demonstrate printing of high-resolution features (
