As the demand for flexible electronic technologies rises, roll-to-roll screen printing has become essential for large-area, mass production, and economic efficiency<sup>(1)</sup>. However, multilayer overlay printing precision is crucial for determining product performance. J. Jeong et al. used tension control to compensate for errors during printing<sup>(2)</sup>, while H. K. Kang et al. applied a feedforward controller for cross-directional alignment correction<sup>(3)</sup>. Despite these advancements, various factors collectively influence overlay printing precision. This study analyzes key factors affecting precision and proposes a model for predicting registration errors. Registration error, measured by CCD camera vision<sup>(4)</sup>, was analyzed by adjusting printing conditions such as gap, printing pressure, printing speed, feeding speed, and tension control gain. Analysis of Variance (ANOVA) and Deep Neural Network (DNN) models identified squeegee pressure, speed, and screen mask-to-web gap as primary factors<sup>(5)</sup>. The results show that registration errors can be calculated without actual printing.
