印刷工藝使用UV上光塗料的註意問題

印刷工藝使用UV上光塗料的註意問題

使用UV上光塗料應註意以下幾點


①光源。
照射光源一般採用高壓汞燈或金屬滷化物燈。高壓汞燈的輸出功率一般為80~120W,才能保證UV塗料的固化速度<0.5s。


②紙張。
UV塗料不適合對容易滲透的紙張進行加工。因為UⅤ塗料中的低分子材料容易滲透到紙張中,引起紙張的變暗甚至浸透。這種情況下,只有對紙張正反兩面都用紫外光照射,才有可能使固化完全。為了預防滲透現象,可先用UV塗料以外的材料塗布底層,以避免塗布UV塗料時出現滲透



③油墨。
需要註意UV塗料與油墨的結合問題,必要時先塗層底膠。



④帶動保護。
UV上光油對皮膚有刺激,加上不揮發,在皮膚衣服上附著時,如果是在夏天高溫天氣的情況下,有可能與汗流起進入皮膚引起炎症,因此如果皮膚沾上UV上光油,應盡快用肥皂水清洗乾凈並及時更換衣服。
