Short-run sampling and customized production with digital textile printing is an attractive option for creative professionals to market their designs in a cost-effective way. The accuracy of color reproduction on the digitally printed textile is crucial for designers. The main objective of this study is to evaluate color reproduction capability of digitally printed silk fabrics based on color gamut and optical density. In addition, color management with ICC profiles was used to investigate the color matching capability of specific spot colors, which were selected from the Pantone^® Fashion + Home digital color library. The accuracy of color matching of digitally printed silk fabrics was evaluated in terms of color difference (ΔE_CMC2:1). Three different silk fabrics - silk chiffon, silk crepe de chine, and spun silk taffeta, were tested and compared. The choice of textile substrate significantly influences image quality. It was found that Crepe De Chine is capable of yielding a wider color gamut and higher optical densities, resulting in better color reproduction capability and color matching. Chiffon has a relatively small color gamut and only can reproduce lighter colors.
