| Summary: | 碩士 === 中國文化大學 === 資訊傳播學系 === 101 === Owing to the rapid curing behavior of UV Inkjet printing, this value-adding product has been widely adopted in the cultural creative industry. Artistic decorations made from ceramic tiles are one common use. In recent years, inkjet printer manufacturers have been constantly developing innovative printing technology. Research related to the improvement of UV Inkjet printing quality has been conducted as well. However, extant research mainly focuses on the output quality optimization. There has been little research based on different characteristic of originals in order to enhance print quality.
Based on developments in variable drop technology and resolution attributes, this study tries to identify the best reproductive modes for different tone of originals. The conclusions provide a reference for manufacturers seeking to develop a user-friendly interface and provide users a convenient way to configure the most appropriate setting according to different tone of originals and thus generate a better image. The research develops nine different printing modes, i.e. Normal dot (3, 5 drop), Variable drop (1,3,5, 1 drop =7 pl), and Different Resolution (720x300dpi、1080x600dpi、1440x1200dpi). The study uses a pair-comparison method of subjective assessment so as to find the appropriate setting that could produce the best UV Inkjet printing quality on ceramic tile.
Proceeding from the theories of Halftone dot and Variable drop technology, the study’s results are virtually identical to the inferences.
The study’s key findings are:
1. Variable drop with high resolution setting could get higher printing quality no matter what kind of the original image tone is.
2. Based on the same resolution, a high-key original image could receive a higher quality by adopting a smaller drop.
3. Based on the same resolution, a low-key original image could receive higher quality by adopting a larger drop.
4. High resolution with small drop will generate better quality regardless of the original image tone.
