  不干胶标签防止沾脏要注意哪些
  What should be paid attention to in the label of self-adhesive
  1、不干胶在印满版实地的时候容易背面沾脏,是由于不干胶表面铜版纸吸墨性差,印刷时尽量用原桶墨,不加6#调墨油,适当加一些去粘剂、防粘剂,天气热时不要加燥油。印满版实地往往容易背面粘脏,通常采用喷粉的办法来解决,尽管印刷防粘脏喷粉剂含有纯植物性材料,分散性和流动性都不错,但是使用喷粉剂会直接影响印刷产品的表面光泽,使墨色不亮,并且污染环境,且对胶印机精度也有影响。
  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、注意胶印水墨平衡,控制好印刷版面水份大小。在不脏印版的前提下使用更少量的版面水份,不干胶平滑、光洁,印满版实地时要先印深颜色,而且墨量印足,以背面不粘脏为准,然后再薄薄地套印上底色,这样的印刷产品光洁度会比较好。
  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、克服胶印中水大墨大的弊端,油墨不能调得太稀薄,太稀则容易背面沾脏,如果太稀可加入部分新墨,以增强油墨粘稠度。
  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.
