紫外線平版印刷適性之研究

紫外線平版印刷技術已日趨成熟，不但應用較為廣泛且相對環保，但仍存在某些問題需要改善，本研究即針對某些被印材料不易著墨問題提出解決途徑，以求能達到品質突破，提升生產作業。本研究首先選用不同的底塗對被印材料進行表面處理，接著使用平版油墨展色機對卡紙、合成聚丙烯、透明聚酯、白色聚氯乙烯、透明聚氯乙烯、霧聚丙烯、透明聚丙烯、特多龍、銀箔紙、鐳射紙十種常用被印材料進行展色印刷，最後進行印刷適性之剝離測試。在剝離測試研究結果發現，（一）油墨印刷於原材上以紙類、合成聚丙烯附著度較佳；對於塑膜類（白色聚氯乙烯、透明聚氯乙烯、霧聚丙烯、透明聚丙烯）等塑膜類和金屬類較不易附著。（二）進行底塗處理1，可改善塑膜類中的透明聚酯、透明聚氯乙烯和金屬類中特多龍、鐳射紙。（三）底塗處理2，因黏度較高，可改善塑膜類白色聚氯乙烯、霧聚丙烯、透明聚丙烯和金屬類中銀箔紙。以上結論可提供為印刷業製程及相關材料廠商之參考。

Since ultraviolet lithography often have many exceptions occur. This study investigated the printing process which is not easy to be improved in inking problems. In order to achieve abnormalities improved, Improve the quality of production operations. Two options viscosity primer before printing, Then use the model IGT C1 lithographic ink color development of material to be printed color printing, finally, printability: Peel testing, The study found the following: The Peel testing:(1) Ink to bristol board and synthetic polypropylene on the original material, better adhesion degree, PET, polyvinyl Chloride, polypropylene and metal relatively easy to attach (2) For primer treatment one can improve PET, polyester, Laser paper. (3) For primer treatment two can improve polyvinyl chloride, polypropylene. In addition to the above conclusions printing work process improvement considerations, and provide relevant materials manufacturers to further improve as the reference.
