傳統印刷版轉向免沖洗印刷版：印刷業低碳製造的發展路徑

From Traditional Printing Plates to Washless Printing Plates: A Development Path for Low-Carbon Manufacturing in the Printing Industry

本研究探討印刷產業導入免沖洗印刷版材以取代傳統PS版或CTP版的效益及發展路徑。透過文獻資料整理與業界案例分析，歸納出採用免沖洗版材後對印刷製程、環境與經營的影響。研究結果顯示，免沖洗版材可省略傳統製版流程中顯影、沖洗、上膠與烘乾等步驟，製程由六步驟縮減為兩步驟，製版時間縮短約60%，大幅提升生產效率。同時，免除了沖版機所需之水資源與強鹼性顯影藥劑，不再產生任何含化學藥劑之廢水，實現製版用水量零耗用並完全杜絕廢液排放。停用沖版設備後，製版耗電量降低，約降低碳排35%。此外，免沖洗版材的使用亦改善了工作環境，免除傳統顯影藥劑對人員健康的危害，同時釋放出約50%的製版設備佔地空間。綜上，免沖洗印刷版有助於印刷業實現低碳化生產，降低資源耗用與污染排放，具備顯著的環境與經濟效益。本研究並據此提出產業推廣建議，以期加速印刷產業的綠色轉型。

This study explores the benefits and development path of adopting washless printing plates to replace traditional PS or CTP plates in the printing industry. Through literature review and industry case analysis, the impact of using washless plates on printing processes, the environment, and business operations is summarized. The results show that washless plates eliminate the steps of developing, washing, coating, and drying in the traditional plate-making process, reducing the process from six steps to two, shortening plate-making time by approximately 60%, and significantly improving production efficiency. Simultaneously, it eliminates the need for water resources and strongly alkaline developing agents required by plate processors, and no longer generates any wastewater containing chemical agents, achieving zero water consumption and completely eliminating wastewater discharge. After discontinuing plate processors, plate-making power consumption decreases, reducing carbon emissions by approximately 35%. Furthermore, the use of washless plates improves the working environment, eliminates the health hazards of traditional developing agents, and frees up approximately 50% of the space required for plate-making equipment. In summary, washless printing plates help the printing industry achieve low-carbon production, reduce resource consumption and pollution emissions, and have significant environmental and economic benefits. Based on this, this study proposes industry promotion recommendations to accelerate the green transformation of the printing industry.
