Lecture
This lecture explores the mechanisms and effects of gravure printing, covering topics such as the coffee ring effect, pattern formation, breakdown mechanisms, and substrate interactions. It delves into the impact of flow speed on line formation, the causes of bulging and scalloping, and the challenges of two-dimensional shape generation. The lecture also discusses instabilities in corners, the role of substrate properties, and the process of air entrapment. Additionally, it examines the filling, wiping, and transferring processes in gravure printing, highlighting the importance of optimizing printing conditions and blade geometry for perfect wiping.
