Multi-parameter Analysis for High-Precision Inkjet Printing

This study provides insights into the effect of different process parameters on the precision of inkjet printing when producing micro scale features. The parameters examined are printing resolution (which controls the droplets center-to-center distances), printing speed as well as printing mode, whether it is unidirectional or bidirectional. The results show that the smallest possible features were achieved with a resolution of 720 dpi. Prints with a higher resolution of 1080 dpi caused the ink to blur and could not be characterized. However, a lower resolution of 360 dpi resulted in larger, but sharper features. The deviation across all measured resolution is below 20%. The findings of this research help identify proper working conditions for cost-efficient high-throughput prints of high precision features in a sustainable manner.
