UV Inkjet Printing has demonstrated extraordinary potential in printing technology around the globe in recent years. Other than its environment-friendly trait, UV Inkjet Printing can also be applied to various printing materials due to its wide range of application. Comparing to the low-price competition invoked by paper-based printing, it achieves high added-value results from its output. While international market’s perspective on inkjet printing remains positive, most printing press in Taiwan still have doubts for the technology. In recent years, there has been a considerable growth in importing UV Width Inkjet printers in Taiwan domestically. However, working personnel in Taiwan are inexperienced in dealing with new equipment and wider selection of printing materials, therefore the issue of printers adapting to their diverse printing materials. This study will examine the five combinations of UV printer and printing materials that are common in Taiwan (brands of printers, serial number of the sprinkler head, and brands of printing ink) and three specific high-value printing substrates (glass, acrylic and melamine plywood). Through the printing experiment, the color gamut of printing materials will be re-examined. The goal of the study is to establish a standard for UV printing’s application in decoration materials, so as to provide reference for future development.
