In order to better understand the drop impaction and post- impaction dynamics of digital textile printing, various numbers of drop-on-demand inkjet drops were deposited on textiles, and the process was visualized using a high speed camera. As a comparison, experiments were also conducted on a high quality inkjet paper under the same conditions. Dynamics of DOD drops accumulation and spreading on the substrates and final state ink distribution show drastic differences between digital printing on textiles and paper. The effect of yarn hairiness on ink deposition was also demonstrated.
