| Summary: | 碩士 === 中國文化大學 === 印刷傳播研究所 === 88 === Among several major solutions to improve printing quality, “standardization” is a key factor for quality control of all segments of the print production process. It will provide solid foundations for manufacturing guidelines, as well as the appraisal indexes of customers to evaluate the color reproduction quality.
The process of this research is first to review the available color control standards and rules internationally. Standards such as SWOP, ISO, GRACoL, and SNAP were analyzed and evaluated. By adapting the functionalities of the above guidelines, a target image based on Printing Technology Research Institute (PTRI) was designed to perform an experimental towards various printers in Taipei area. A set of data was collected and analyzed to find out whether the color reproduction consistency were influenced by lacking standardized production guidelines.
The conclusions of the experiment are follow:
1. Under the same printing condition (same press, paper, ink, and printing plate), the printing results have no significant difference between each print-out.
2. By providing an approved proof sheet made by outside printers, does not help the printer to produce consistent color reproductions. That means it is useless to ask printer to follow an existing proof not done by their own production facilities although the printing materials keep the same.
3. Due to its production process, there are significant printing result differences between different printers, although they use same plate, paper, and ink.
4.If the plate-making is not done in-plantly, there will be significant color differences of the reproduction results compare to the plates were made in-plantly.
After examined the experiment results, the research found the quality of color reproduction is difficult to control without specific guidelines. To answer the research question: “Should we formulate a national quality-controlling standard for printing color reproduction?” The research then conclude that indeed there is a need to establish a national color control standard (guidelines) for printing color reproduction.
