瓶盖基本上都采用PP和PE材料,选择的油墨必须与承印材料的类型相匹配。选择油墨时,主要应注意以下两点。在塑料瓶盖移印中,油墨的选择至关重要。如果必须使用网印UV油墨,则应在其中加入一定量的胶化剂。尽管溶剂型网印油墨可用于移印,但其效果也不如专门的移印油墨好。如果需要用UV油墨,则更不应选用网印UV油墨,因为网印UV油墨的转移性太差。<br style="margin: 0px; padding: 0px; border-radius: 0px; color: rgb(102, 102, 102); text-transform: none; text-indent: 28px; letter-spacing: normal; font-family: "Microsoft YaHei"; font-size: 14px; font-style: normal; font-weight: 400; word-spacing: 0px; list-style-type: none; white-space: normal; orphans: 2; widows: 2; box-shadow: none; background-color: rgb(255, 255, 255); -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal; text-decoration-style: initial; text-decoration-color: initial;"><br style="margin: 0px; padding: 0px; border-radius: 0px; color: rgb(102, 102, 102); text-transform: none; text-indent: 28px; letter-spacing: normal; font-family: "Microsoft YaHei"; font-size: 14px; font-style: normal; font-weight: 400; word-spacing: 0px; list-style-type: none; white-space: normal; orphans: 2; widows: 2; box-shadow: none; background-color: rgb(255, 255, 255); -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal; text-decoration-style: initial; text-decoration-color: initial;">(1) 一些油墨中添加了硬化剂,使附着效果得以改善,但增加了的难度,因此除非客户有特别要求,否则建议最好不要采用此法。<br style="margin: 0px; padding: 0px; border-radius: 0px; color: rgb(102, 102, 102); text-transform: none; text-indent: 28px; letter-spacing: normal; font-family: "Microsoft YaHei"; font-size: 14px; font-style: normal; font-weight: 400; word-spacing: 0px; list-style-type: none; white-space: normal; orphans: 2; widows: 2; box-shadow: none; background-color: rgb(255, 255, 255); -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal; text-decoration-style: initial; text-decoration-color: initial;"><br style="margin: 0px; padding: 0px; border-radius: 0px; color: rgb(102, 102, 102); text-transform: none; text-indent: 28px; letter-spacing: normal; font-family: "Microsoft YaHei"; font-size: 14px; font-style: normal; font-weight: 400; word-spacing: 0px; list-style-type: none; white-space: normal; orphans: 2; widows: 2; box-shadow: none; background-color: rgb(255, 255, 255); -webkit-text-stroke-width: 0px; font-variant-ligatures: normal; font-variant-caps: normal; text-decoration-style: initial; text-decoration-color: initial;">(2) 网印油墨的流平性较好,而移印油墨则有更好的胶质性;网印油墨的干燥速度相对较慢,移印油墨的干燥速度较快。最好选用移印油墨而不是网印油墨。
