      冬夏交替 柔性版印刷
      如何360°全方位避免翹版

      印刷車間環境夏季悶熱潮濕,冬天低溫寒冷?貼版部車間溫度面臨極端挑戰,如何選擇合適的貼版膠帶呢?

      貼版膠帶種類繁多,很多膠帶供應商都承諾他們的膠帶性能完美。但是正如“一千個讀者眼中有一千個哈姆雷特”一樣,冬夏交替換季時溫度忽高忽低,每一個車間的環境和設備情況都不盡相同。

      一些常見參考標準

      01膠帶粘接在套筒上時,印版邊緣翹起

      制版過程中產生的污染物,如肥皂、油污、脂類或殘留光聚合物,都會對膠帶性能產生負面影響,引起翹版問題。

      ?

      解決方案:

      1. 選擇合適粘接強度的貼版膠帶——印版較厚時需更強的粘接力,才能保持印版邊緣持久粘接。

      2. 貼版時施加足夠的壓力:使用橡膠輥或施壓輥,對前后邊緣施加相同的壓力。

      3. 貼版后快速檢查,用拇指牢牢按在印版的圖案區域——如果下面區域看起來比周圍區域暗,則表明貼版時未能施加足夠的壓力。對于非常苛刻的情況,可使用封版膠帶或合適的封板筆

      02如何避免膠帶與印刷套筒或輥筒粘接面出現氣泡:

      膠帶和套筒之間的粘接力受到干擾。例如,膠帶和套筒之間的溫差引起濕氣進入,或套筒表面其他污染物。

      ?

      解決方案:

      1. 貼版前,確保在相同溫度下存放所有組件。

      2. 確保正確清潔套筒且無污垢或油墨殘留物來影響膠帶粘接力。

      3. 貼版前若使用清潔劑清潔套筒,則需要保證貼版前有足夠的揮發時間,這點對于有刮痕或受損套筒非常重要,因為這種套筒容易吸入濕氣

      03印版與膠帶同時脫離套筒,整體翹起

      為什么印版會整體翹起?

      當膠帶和套筒之間的粘接力小于膠帶和印版之間的粘接力或未遵循貼版指南時,可能會發生整體翹起。

      ?

      整體翹版解決方案

      1. 選擇與所用套筒匹配的貼版膠帶,貼膠帶時向套筒施加足夠的壓力。

      2. 確保印版和膠帶粘貼的接縫處不重疊。

      3. 控制生產環境的溫度和濕度。
