Printed electronics such as solar cells, RFIDs, and display panels can be made using printed electronic technology by printing viscous liquids having various properties on films or insulating substrates. Among printed electronic production processes, the roll-to-roll process transfers functional ink to an insulation substrate by filling its engravings through repeated contact and rotation of two rolls. Extensive research has been conducted to commercialize this process because it offers several advantages such as low equipment investment and production cost, and high-speed mass production. However, the roll-to-roll process requires further development for commercialization because print quality precision and fine pattern formation are difficult to achieve, and print quality may be affected by processing precision errors and non-uniform printing pressure. Contact printing pressure is the pressure acting on the nip that makes contact with the two rolls, and is a factor that influences roll processing precision. That is, contact printing pressure uniformity must be maintained to enhance print quality. However, previous research on contact printing pressure failed to directly estimate the contact printing pressure due to structural problems, and only indirectly measured it by attaching a load cell at both ends of the impression roll. This study proposes a method of contact printing pressure estimation and control to enhance print quality. The processing precision of a roll can be measured by measuring the rotationally repeatable run-out after dividing the width of the impression roll and plate roll into 25 points. The relationship between the impression roll and the plate roll, with consideration of the contact printing pressure, rotationally repeatable run-out, and force measured by the load cell, is modeled in a manner similar to the relationship between a car body, suspension, and ground in a half-car model, and expressed using state-space equations. This model is then applied to an individual drive type cross-coupled control system for experiments on control of the contact printing pressure; pressure measuring films are used to check for actual improvement in uniformity of contact printing pressure.

可以使用印刷电子技术通过在膜或绝缘基板上印刷具有各种特性的粘性液体来制造诸如太阳能电池，RFID和显示面板之类的印刷电子产品。在印刷电子生产工艺中，卷对卷工艺通过重复接触和旋转两个辊来填充其雕刻，从而将功能性油墨转移到绝缘基材上。为了使该工艺商业化，已经进行了广泛的研究，因为它具有许多优点，例如设备投资和生产成本低，以及高速批量生产。但是，卷对卷工艺需要进一步发展以实现商业化，因为难以实现精确的打印质量和精细的图案形成，并且打印质量可能会受到处理精度误差和打印压力不均匀的影响。接触印刷压力是作用在与两个辊接触的辊隙上的压力，并且是影响辊加工精度的因素。即，必须保持接触印刷压力均匀性以提高印刷质量。然而，由于结构问题，先前关于接触印刷压力的研究未能直接估计接触印刷压力，而仅通过在压印辊的两端安装测力传感器来间接地测量接触印刷压力。这项研究提出了一种接触印刷压力估计和控制方法，以提高印刷质量。辊的加工精度可以通过在将压印辊和印版辊的宽度划分为25点之后测量旋转可重复跳动来测量。考虑到接触印刷压力，旋转可重复跳动和测力传感器测得的力，压印辊和印版辊之间的关系以与车身，悬架和车身之间的关系相似的方式建模。在半车模型中接地，并使用状态空间方程表示。然后将该模型应用于单独的驱动式交叉耦合控制系统，以进行接触印刷压力控制的实验。压力测量膜用于检查接触印刷压力均匀性的实际提高。考虑到接触印刷压力，可旋转重复跳动和称重传感器测得的力，以类似于半车模型中的车身，悬架和地面之间的关系的方式建模，并使用状态空间方程。然后将该模型应用于单独的驱动式交叉耦合控制系统，以进行接触印刷压力控制的实验。压力测量膜用于检查接触印刷压力均匀性的实际提高。考虑到接触印刷压力，可旋转重复跳动和称重传感器测得的力，以类似于半车模型中车身，悬架和地面之间的关系的方式建模，并使用状态空间方程。然后将该模型应用于单独的驱动式交叉耦合控制系统，以进行接触印刷压力控制的实验。压力测量膜用于检查接触印刷压力均匀性的实际提高。然后将该模型应用于单独的驱动式交叉耦合控制系统，以进行接触印刷压力控制的实验。压力测量膜用于检查接触印刷压力均匀性的实际提高。然后将该模型应用于单独的驱动式交叉耦合控制系统，以进行接触印刷压力控制的实验。压力测量膜用于检查接触印刷压力均匀性的实际提高。
