The digitalized preprinting technology is one of the most important manufacturing processes on reducing the environmental pollution. Nowadays, the digitalized preprinting technology is frequently used instead of the traditional printing process. This kind of printing method will be the essential tecnology for textiles in the future. The colorimetric characterization of this technology on cotton textile is investigated in this study for cotton fabrics to improve the fidelity of the colour-reproducting images on the samples made of cotton fabric. The results indicate that the duplicates made by the digitalized preprinting technology method with colorimetric characterization have better colour fidelity than those by that without it.
