以碳排數據探討印刷色彩標準化與減碳的關係

Using Carbon Emission Data to Explore the Relationship Between Printing Color Standardization and Carbon Reduction

本研究將以碳排放數據探討色彩標準化過程與減碳的關係。以量測及調整色彩達到G7或ISO12647-2等色彩標準化數值之前所產生的碳排量。研究過程中以手工量測、人工控墨及自動化量測加上連續式回饋調整(Closed-Loop)等二種方式，依據經驗值估算此二種方式對碳排量產生的影響，估算的結果為第一組採用人工量測及人工控墨的年碳排總量為962.495公噸CO2e/年，第二組採用自動量測加上自動控墨系統的碳排總量為281.087公噸CO2e/年，約手工量測及手工放墨所產生碳排量的四分之一，相較之下採用自動量測及控墨方法，一年的減碳量高達681.408公噸CO2e/年，此數據也遠高於一般印刷廠碳盤查時範疇一及範疇二的總碳排量（一般一至二台印刷機的廠商碳排約為100~300公噸CO2e/年）。而在調整色彩至標準值的過程中，影響碳排量最大的前二項因子為紙張及電力。

This study will use carbon emission data to explore the relationship between the color standardization and carbon reduction in printing process. To measure and adjust the carbon emissions produced before reaches color standardization values such as G7 or ISO12647- 2. During the research process, two methods were used: manual measurement, ink control and automated measurement with continuous feedback adjustment (Closed-Loop). The impact of these two methods on carbon emissions was estimated based on empirical values, and the carbon emissions of the first method that uses manual measurement and manual ink control is 962.495 tons CO2e. The carbon emissions of the second method that uses automatic measurement and automatic ink control systems is 281.087 tons CO2e, which is about 962.495 tons of CO2e. One-quarter of the carbon emissions of the first method. In comparison, using automatic measurement and ink control methods can reduce carbon emissions by up to 681.408 tons CO2e. In the process of adjusting colors to standard values, the top two factors that have the largest impact on carbon emissions are paper and electricity.
