| Summary: | 碩士 === 中國文化大學 === 資訊傳播學系 === 102 === Because of the wastewater containing hazardous substances, traditional textile printing industry is still regarded as polluting industries. Therefore, traditional textile printing is gradually replaced with digital inkjet printing. Digital inkjet printing on textile used thermal sublimation transfer printing before, it printed on transfer paper then transferred image to textile. This way is belonging to two step printing works. With the advancement of digital inkjet printing, the direct-to-textile sublimation printing is developed. The printing process is directly print on textile without transfer paper. It reduces the transfer paper cost.
This research uses different Dye Sublimation Processes (Direct-to-Textile Sublimation Printing, Thermal Sublimation Transfer Printing), different Resolution (600x600,600x900)and different Heat temperature(180℃,200℃,220℃), Hot-pressing temperature(190℃,200℃,210℃)of combinations printed on the polyester material. The data measured by the instruments are used to assess the objective quality, and a psychophysical subjective assessment conducted as well to find the best printing method of Dye Sublimation on textile. In addition, the textile will have a phenomenon of color fade after a long period of time. Therefore, this study will also include a color fastness test to understand whether the two dye-sublimation process of color fastness are different. The results showed as follows:
1.Effectively improve the resolution and fixing temperature, both dye sublimation and sublimation transfer can get a better color performance and fixing temperature control has even greater influence to enhance the printing quality.
2. Thermal Sublimation Transfer Printing have better washable, light fastness
3. On subjective visual assessment by psychologically physical quantity method, thermal sublimation transfer printing have better human visual preference.
