  不干膠標簽防止沾臟要注意哪些
  What should be paid attention to in the label of self-adhesive
  1、不干膠在印滿版實地的時候容易背面沾臟,是由于不干膠表面銅版紙吸墨性差,印刷時盡量用原桶墨,不加6#調墨油,適當加一些去粘劑、防粘劑,天氣熱時不要加燥油。印滿版實地往往容易背面粘臟,通常采用噴粉的辦法來解決,盡管印刷防粘臟噴粉劑含有純植物性材料,分散性和流動性都不錯,但是使用噴粉劑會直接影響印刷產品的表面光澤,使墨色不亮,并且污染環境,且對膠印機精度也有影響。
  1. Self adhesive is easy to get dirty on the back when printing the full plate on the spot. It is due to the poor ink absorption of the paper on the surface of the self adhesive. When printing, try to use the original barrel ink instead of adding 6 × inking oil. Add some adhesive remover and anti adhesive properly. Do not add dry oil when the weather is hot. On the spot, the printing full plate is easy to stick dirty on the back. Usually, the method of powder spraying is used to solve the problem. Although the anti sticking powder spray contains pure plant materials, and has good dispersivity and fluidity, the use of powder spray will directly affect the surface gloss of the printing products, make the ink color not bright, and pollute the environment, and also affect the accuracy of the offset press.
  2、注意膠印水墨平衡,控制好印刷版面水份大小。在不臟印版的前提下使用更少量的版面水份,不干膠平滑、光潔,印滿版實地時要先印深顏色,而且墨量印足,以背面不粘臟為準,然后再薄薄地套印上底色,這樣的印刷產品光潔度會比較好。
  2. Pay attention to the balance of offset ink and control the water content of the printing plate. On the premise of no dirty printing plate, use the least amount of water in the plate. The adhesive is smooth and smooth. When printing the full plate on the spot, first print the deep color, and the ink amount is enough, subject to no dirty on the back, and then apply the background color thinly. Such printing product will have a better finish.
  3、克服膠印中水大墨大的弊端,油墨不能調得太稀薄,太稀則容易背面沾臟,如果太稀可加入部分新墨,以增強油墨粘稠度。
  3. To overcome the disadvantages of water ink in offset printing, the ink can not be adjusted too thin, too thin, it is easy to get dirty on the back, if too thin, you can add some new ink to enhance the viscosity of the ink.
