為什麽曬好的印刷版有藍

在生產中,一張版曬出來,不管是因為版材前期製作的問題,還是曬版本身曝光和顯影時間的匹配條件不合適,曬出的版上有底藍。



出現底藍的“秘密”在於

①版材製作時,砂目過粗,電解氧化的電流不匹配;

②曬版時曝光不足,或顯影液濃度不夠,或者是這兩個條件匹配得不合適。

底藍現象令許多操作人員頭疼,出現這個問題時,多顯影不行,少顯影也不行。多顯影的話,需要保留的網點就要縮小,或是丟失;少顯影的話,則影響整個版面。

在曝光顯影適度的條件下,顯完影後有底藍就要修臟,但一修臟,版面上就會有水印,去完水印的印版,上機印刷,而水印洇出的周圍又要上臟。如果再用修臟液修完這一圈臟後,又會洇出另一圈臟。若是洇在圖片、文字或網線上,印版就根本不能使用了。要解決這個問題就要在去臟之前,塗上薄薄的一層膠,而高質量的印刷品則不能再用此版了。
