Synthetic dye is relatively cheap with attributes that render it easy to use compared to natural dye; hence, it has been extensively developed with increasing industrialization. However, synthetic dye and the current dyeing method have caused various environmental problems, including CO 2 emission and wastewater generation, necessitating research on eco-friendly dyes and dyeing. This study checked whether the natural indigo dye (Indigofera tinctoria) is derived from natural ingredients by measuring the 14 C (Biocarbon) present in it. In addition, we investigated the persistence and stability of digital textile printing (DTP) ink, which is derived from natural indigo dye by testing pH, absorbance, maximum absorption wavelength, viscosity, electric conductivity, surface tension, and particle size distribution for 90 days. Furthermore, the performance of natural indigo DTP ink and printing fabric was evaluated by inspecting the change in color fastness and corresponding index substances before and after digital printing with natural indigo DTP ink on textiles.
