twill and honeycomb fabrics were selected as the research objects, and the same cold padbatch treatment, pretreatment and ink-jet printing were performed on the three fabrics. The roughness, thickness, porosity, color strength and outline sharpness of fabrics were measured. The influence of pretreatment on fabric structures and the relationship between fabric structures and color strength and outline sharpness were analyzed. The results show that the warp roughness, weft roughness, thickness, and porosity of the plain fabric are 6.4 μm, 9.1 μm, 0.65 mm and 85.5%, respectively. Those of the twill fabric are increased by 22%, 30%, 25% and 2.5% compared with those of the plain fabric, respectively. While those of the honeycomb fabric are increased by 50%, 53%, 150%, and 3.4% compared with those of the plain fabric, respectively. The warp roughness, weft roughness and porosity of plain, twill, and honeycomb fabrics after cold pad batching and pretreatment are reduced, but fabric thickness is increased. In addition, the plain fabrics exhibit the lightest color strength and the best outline sharpness, followed by twill and honeycomb fabrics, which display the darkest color strength and the
worst outline sharpness after the same treatment.
