以ICC色彩描述檔印製圖案應用於尼龍針織物昇華熱轉移，數位印花對色彩值與物性之研究

Study on the color value and physicalproperties of Nylon knitted fabrics bydigital heat transfer printing based onthe ICC profile system

本研究主要探討以客製ICC 色彩描述檔及系統預設Photoshop 日本色彩數位輸出方式製作昇華熱轉移印花紙對尼龍針織物進行熱轉印數位印花，並與市售標準樣相比針對印花色彩值、相似度、耐水洗牢度、耐摩擦牢度、耐昇華牢度及織物柔軟度進行深入探討。由實驗結果發現，於190° C 壓印35 秒之顏色外觀力度值（K/S） 最佳，且使用客製ICC 色彩描述檔輸出之熱印紙其轉印布色差值較系統預設Photoshop 日本色彩輸出者小。尼龍針織物經昇華熱壓印後的顏色牢度約為4 級以上呈良好狀態，而柔軟度下降率則隨著溫度上升而增加，當190° C 40 秒時柔軟度下降稍明顯，此可能導致面料的手感及外觀變差。另，由意象評定調查得知，大多數人以裸眼直觀評定以使用客製ICC 輸出圖檔所轉印的布面色彩較接近於市售標準布樣，因此使用印刷技術常用之ICC 色彩輸出方式製作昇華熱轉移印花紙並應用於紡織數位印花將比系統預設Photoshop 日本色彩輸出更具良好的數印色彩再現性。

Digital technologies are prominent at every stage oftextile printing. The setting of ICC profile is an importantrole in the color quality of digital printing. The emphasisin this research is comparison the color differenceand reproducibility of setted ICC Profile with defaultPhotoshop Japan color system for sublimation heattransfer digital printing of Nylon knitted fabrics. The colorvalue and imagery were compared to controlled samplesand color fastness(such as washing, rubbing, sublimation)and softness of printed fabrics were investigated. Fromresults show that apparent color intensity (K/S) obtainsthe best result at 185℃ , 35 second printing condition andthe color difference using setted ICC profile was lowerthan Photoshop Japan color system. The color fastnessof sublimation digital printed fabrics were good abovedegree 4 but softness of fabrics were slightly decreasedwith increasing printing temperature. Additionally, thecolor imagery test indicated that using ICC Profile tomade sublimation digital printing paper for printedfabrics should be near controlled samples and be betterreproducibility.
