Optimization of Digital Transfer Textile Printing Process using Multi-Objective Function Analysis

Abstract

Digital textile printing (DTP) is widely used because it is more efficient and simpler than conventional textile printing methods. Digital transfer textile printing (DTTP) is one of the most efficient and simplest DTP methods. In this study, the optimum process conditions for DTTP have been investigated, to minimize the distortion of printed images and maximize the color reproducibility. First, a novel measurement method for fabric shrinkage and image distortion was developed. Then 9 characteristic values were defined and a series of experiments were designed and performed using the Taguchi method. Finally, two different multiple-characteristic value analyses were performed on the results. In one method, 9 characteristic values were converted into a single value. In the other method, the characteristic values were divided into 3 groups for analysis. Finally, results from the two methods were compared to determine which method was more suitable.
