平版印刷國際標準應用於柔版印刷之可行性探討

A Feasibility Study on Applying G7 Expert Certification from Offset to Flexographic Printing

隨著疫情後數位化與電商的興起，全球包裝印刷市場快速變動，柔版印刷因其環保、成本低與數位製版的特性，逐漸成為國際主流趨勢。臺灣目前在柔版印刷之研究與應用相對薄弱，印刷品質控制亦面臨諸多挑戰。本研究旨在探討以平版印刷為基礎的G7國際色彩認證標準，應用於柔版印刷的可行性。研究方法採用半結構式專家訪談，對象涵蓋柔版印刷廠商管理者、色彩顧問與已導入G7認證之實務代表，從印刷品質適性、色彩標準化、導入挑戰與策略等面向進行深入分析。研究結果顯示，G7對於改善柔版印刷中的網點擴大、印刷反差與色彩穩定性具顯著效益，尤其在灰平衡與階調一致性控制方面具關鍵作用。然而，G7對於滿版濃度與疊印能力的改善仍須仰賴印刷設備與材料層面的調整。導入G7認證亦需克服跨部門協作、人才培訓與管理流程等挑戰。整體而言，透過分階段導入策略與色彩數位化管理系統（如Esko Equinox）整合，G7可提升柔版印刷之品質穩定性、數位化程度與國際競爭力，並與ESG永續目標形成連結，協助臺灣印刷產業邁向高品質與永續化發展之路。本研究的貢獻包括提供臺灣柔版印刷導入G7認證的實務可行性分析與具體導入策略；促進印刷產業色彩管理系統之標準化與數位化，回應國際品牌對品質一致性的需求；連結G7認證與永續經營目標，為企業落實ESG提供技術依據與管理方向，具備產業推廣與學術參考價值。

In the post-pandemic era, the rapid rise of digitalization and e-commerce has significantly reshaped the global packaging and printing industry. Flexographic printing has emerged as a mainstream trend due to its environmentally friendly nature, low cost, and compatibility with digital plate-making. However, in Taiwan, research and application of flexographic printing remain relatively limited, with various challenges in print quality control. This study aims to explore the feasibility of applying the G7 expert certification that originally developed for offset printing to flexographic printing. Using a semi-structured expert interview method, the study interviewed managers from flexographic printing companies, color consultants, and industry professionals who have already implemented G7 certification. The analysis focused on print quality suitability, color standardization, implementation challenges, and strategic solutions. Results indicate that G7 is particularly effective in improving dot gain control, print contrast, and color stability, especially through gray balance and tonal consistency management. However, its effectiveness in addressing solid ink density and overprint capabilities is limited, as these factors still depend on physical adjustments to printing equipment and materials. Despite these limitations, the staged implementation of G7, when integrated with digital color management systems such as Esko Equinox, can enhance the overall print consistency, digital transformation, and international competitiveness of Taiwan's flexographic printing sector. Furthermore, aligning G7 adoption with ESG sustainability goals can contribute to the industry’s transition toward high-quality and sustainable development. This study contributes by providing a practical feasibility analysis and phased implementation strategy for G7 certification in Taiwan's flexographic printing industry; by promoting standardization and digitalization of color management systems to meet international brand expectations for quality consistency; and by linking G7 certification to ESG objectives, offering a technical and managerial framework to support sustainable corporate practices. The findings are valuable for both industry practitioners and academic researchers.
