聚丙烯底漆處理應用UV噴墨之印刷色彩品質研究

The Study on Printing Quality Attributes of Polypropylene Primer Coating Used UV Inkjet

摘要


UV印刷在國內與國際皆有成長,其應用層面廣泛吸引印刷業外的產業投資,另外政府倡導降低VOCs氣體排放,更讓UV印刷不離環保的議題,然而UV油墨成分當中確實較傳統油墨所還有的溶劑減少許多,但是其在多元材質應用上卻有著另外汙染的途徑。在進行塑膠材質或者表面張力低、非極性,且怕高溫的材質時,需要經過前處理塗布才能獲得較好的附著度。因此UV噴墨在數位噴墨市場中比例逐漸增加時,伴隨著塗布所造成的揮發性氣體也會增加。故本研究以傳統溶劑塗布與環保水性塗布兩種塗布處理與3種塗布厚度的方式於聚丙烯(Polyprop ylene,PP)材質上,經過UV噴墨印刷後,對樣本進行色彩品質特性量測分析以及物理特性分析,將實驗分析後得到塗布處理與塗布厚度之最佳組合。本研究之結論如下:平均色差中可看出溶劑型塗布厚度影響色彩表現是較為明顯,而水性組內則是厚度越厚色差越明顯。在色域表現方面,亮部調色域差異最大,溶劑型的組內色域大小與塗布厚度間5μm厚度與10μm厚度可達到相同色域範圍,15μm時色域範圍有顯著的增加,而在水性塗布組內則可發現5μm厚度時色域最小,10μm厚度色域最大15μm厚度色域大於5μm厚度。在印刷對比的部分K、C版的色彩表現優於M、Y版,並可以透過對比值發現當在溶劑與水性兩種塗布性質塗布厚度越厚印刷對比值越好。在各色版的階調擴增值普遍在亮部調網點百分比較傳統印刷來得高。水性塗布處理對於印刷品質與色彩上與溶劑型塗布處理並沒有顯著的差異,甚至能夠擴大色域範圍,也能達到環保降低廢水與VOCs氣體污染的目的。

UV printing both in domestic and international have obviously growth, the application wide so attract many industrial investment in the UV inkjet printing,besides government advocacy to reduce VOCs gas emissions, enhance UV inkjet printing to be a hot resolution, however, the UV ink composition which is indeed lower solvent than the traditional ink, but it has the other pollution in the multi material applications. During plastic material have lower tension, non-polar, or fear of high temperature its need coating process that can be used in printing, aftercoating process the primer can increase the adhesion on the materials surface. UV inkjet market share has increased along with the coating caused by the volatile gaswill increase. In this study, a traditional solvent primer with environmentally friendly water-based primer both coated handle with three kinds of coating thickness inpolypropylene (Polypropylene, PP) material on the samples and after UV inkjet printing measure the printing quality characteristics find out the better primer coating and coating thickness combination. Through the experimental analysis provided to the production, government, academia, research sector as a reference.
