In recent years, roll-to-roll-printed-electronics have attracted attention to manufacture flexible devices such as polymer electrolyte fuel cell or lithium-ion secondary battery. The technology can mass-produce flexible devices bacause the technology continuously forms electric circuit by dropping conductive ink on film which is transported by many rollers. However, the technology has not been put to practical use bacause there are many problems in this technology. Where, trough and wrinkling gives an example as the defects which is occurring in the process. If these defects occur on the film in manufacturing process, performance of formed circuit significantly decreases. Consequently, we need to prevent defects. Therefore, in this study, we suggest preventing method of these defects by image recognition technique as a pre-stage to construct of mechanism.
