[Display omitted] •New criteria are proposed for evaluation of the printability of microscale patterns with various printing defects.•Using the criteria, conditions that can be easily tuned in roll-to-roll printing were optimized by a statistical technique.•Under the optimal conditions, sub-30-μm multilines, which have few printing defects, were obtained.•A dimensionless metric was defined for objective evaluation of the printability using the proposed criteria. This study proposed new criteria for numerical evaluation of the printability of microscale patterns with various printing defects. Based on these criteria, printing conditions that could be easily tuned in roll-to-roll gravure printing were optimized by a Box–Behnken design of experiment. Under the optimal conditions, sub-30-μm multilines, which have few printing defects, were obtained. Finally, a dimensionless print quality metric was defined for an objective evaluation of printability based on the proposed criteria following verification of its viability.
