瓶蓋基本上都采用PP和PE材料，選擇的油墨必須與承印材料的類型相匹配。選擇油墨時(shí),主要應(yīng)注意以下兩點(diǎn)。在塑料瓶蓋移印中，油墨的選擇至關(guān)重要。如果必須使用網(wǎng)印UV油墨，則應(yīng)在其中加入一定量的膠化劑。盡管溶劑型網(wǎng)印油墨可用于移印，但其效果也不如專門的移印油墨好。如果需要用UV油墨，則更不應(yīng)選用網(wǎng)印UV油墨，因?yàn)榫W(wǎng)印UV油墨的轉(zhuǎn)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劑，使附著效果得以改善，但增加了的難度，因此除非客戶有特別要求，否則建議最好不要采用此法。<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) 網(wǎng)印油墨的流平性較好，而移印油墨則有更好的膠質(zhì)性；網(wǎng)印油墨的干燥速度相對較慢，移印油墨的干燥速度較快。最好選用移印油墨而不是網(wǎng)印油墨。
