奈米材料對數位影像輸出用紙影響之研究－－彩色噴墨印刷適性

A Study of Nanoparticle Materials on the Effect of Digital Imaging Output Paper —Color Inkjet Printing Compatibility

噴墨印刷是無壓印刷主要型態之一，亦為未來數位印刷重要趨勢。為要求彩色噴墨印刷適性有優異表現，其數位影像輸出用紙必須予以塗佈。又奈米材料具有高表面積/體積比，及傑出機械、光、電、磁、表面等特性。本研究以碳酸鈣顏料之奈米材料加入塗佈之製作，以不同比例顏料與混合配方改變之調配塗料，並使用這些塗料與原紙以塗佈機完成新型數位影像輸出用紙。最後將其經由噴墨印表機，利用分光光譜儀進行色彩數據量測，再以色彩導表評估與分析。研究結果證實，加入碳酸鈣顏料之奈米材料塗佈後，此數位影像輸出用紙之彩色噴墨印刷適性，其色相較不易產生偏移且整體的色域範圍也擴大；對於所有的暗部明度值明顯增加；色彩分佈情形呈現更均勻一致；紙張與印墨之間配合良好，並獲致更高等級數位影像輸出用紙之改善。

Inkjet printing is the main one of the nonimpact printing and the important trends of the digital printing in the future. In order to get excellent color inkjet printing compatibility, its digital imaging output paper should be coated. Besides, owing to nanoparticle materials have high surface/volume ratio, and outstanding mechanical, optical, electrical, magnetic characteristics. This research is to take nanoparticle materials of CaCO3 pigment into coating and changes the ingredients by adjusting the proportion of the pigment, then uses these coatings and base paper with coater to make a novel digital imaging output paper. At last evaluates and analysis from color target chart through spectrophotometer color data on digital imaging output paper with inkjet printer. The research result has showed that color inkjet printing compatibility of digital imaging output paper of taking nanoparticle materials of CaCO3 pigment into coating improves the hue shift condition and broadens out whole color gamut domain; the brightness of total shade area increases clearly; color profile distributes evenly; the suitability between paper and ink is very good, and makes higher grade digital imaging output paper.
