Abstract
Recently, printed electronics technology can be used in conductive printed patterns and flexible displays. The transfer ratio in this process is influenced by the conditions of the printing surface, the properties of the conductive ink material, and the printing speed, which are important factors that affect the printing quality. This study examines the transfer characteristics of conductive ink transferred from various micro-patterns onto flexible film substrates using a roll-to-plate process. Various patterns with different aspect ratios were printed at different printing speeds to determine the ink transfer characteristics and printability. The optimum printing speed for characterizing the printing quality is related to the shape of the patterns, and it is more affected by the depth than the width of the pattern according to experiments. The transfer ratio increases with the force aspect ratio.
