關於包裝印刷廠印後錶面處理對印刷品顏色的影響

印刷品的錶面處理屬於包裝印刷廠印後加工範疇,其對印品的顏色也會產生一定的影響,影響較大的主要有錶面覆膜(亮光膜、亞光膜)、上光(罩亮光油、亞光油、UV光油)等工藝。

印品經過包裝印刷廠錶面處理後,會有不同程度的色相變化和色密度變化。這些變化分為物理變化和化學變化物理變化主要體現在產品錶面增加了鏡面反射和漫反射,這對色密度有一定影響。

化學變化主要來自覆膜膠、UV底油、UV油內含有的多種有機溶劑,它們會使印刷墨層的顏色發生變化。

重點需要關註的如下：

覆亮光膜、罩亮光油和UV油時:色密度增加,光澤度增大

覆亞光膜、罩亞光油時:色密度降低,光澤柔和
