怎么看画册覆膜的质量?

  印刷都有很多的工艺,我们前面也讲了很多,那么画册印刷我们用到多的一道工艺就是封面封底覆膜的工序,覆膜工艺是一个必须具备的工序,也是一些画册基本的工艺,因为在画册表面如果颜色印刷得太淡,那么轻轻一碰触就会留下一些指印,所以我们要对它进行一些表面的处理,就是覆膜、那么它的质量好坏我们应该如何去鉴定呢?下面就来详细的介绍一下。

  Printing has a lot of technology, and we talked a lot about it before. So the most common technology we use in album printing is the process of covering the cover and the bottom. The process of covering the film is a necessary one and also a basic process of some albums. Because if the color of the album is too light, then a touch will leave some fingerprints, so we need to make it. Some surface treatment, that is, film coating, so how should we identify its quality? Here is a detailed introduction.

  一般覆膜有热覆膜和冷覆膜基本的两种方式,我们下面就来简单的介绍一下覆膜的质量问题我们分别给归纳了以下几点来分析一下。

  Generally, there are two basic ways of hot and cold film covering. Let's briefly introduce the quality problems of film covering. We summarize the following points to analyze.

  1:首先我们可以拿一本覆膜好的画册印刷做实验,将适当面积的覆膜样张取出来,然后进行来回的揉搓,如果揉搓后没有出现气泡和脱离的现象,就证明覆膜的质量是非常不错的,而如果出现粘合的或者气泡之类的现象,就说明的质量是有问题的,应该及时的进行改进或者是重新进行覆膜工序。

  1: First of all, we can take a good picture album with film covering to do the experiment, take out the appropriate area of film covering sample, and then rub it back and forth. If there are no bubbles and detachment after rubbing, it will prove that the quality of film covering is very good. If there is adhesion or bubbles and other phenomena, it means that the quality is problematic and should be carried out in time. Improvement or re-coating process.

  2:覆膜样张上都会有一层塑料薄膜,轻轻的撕下来看看,如果纸张上的纤维和表面的墨层都有粘黏在薄膜.上的话,就说明覆膜是非常牢固的,质量也是比较好的,如果可以轻易地就撕下,没有任何的粘黏情况,就证明这道覆膜工序是非常失败的。

  2: There will be a layer of plastic film on the sample sheet, tear it off gently. If the fibers on the paper and the ink layer on the surface are sticky to the film, it shows that the film is very strong and the quality is better. If it can be easily torn off, there is no sticky situation, it proves that the film coating process is very unsuccessful.

  3:另外也可以把覆膜的样张放进去烘道机里面实验。看看在高温的状态下覆膜纸张所呈现的一个状态,如果出现了脱模或者是气泡的现象,就说明覆膜的质量差,质量好的覆膜即使在高温也依旧是平整不起皱的状况。

  3: In addition, we can also put the sample of film coating into the dryer for experiment. Look at the state of the coated paper at high temperature. If demoulding or bubbles occur, it shows that the quality of the coated film is poor. Even at high temperature, the coated film with good quality is still flat and wrinkle-free.

  4:把覆膜纸张放进水里面浸泡一到两个小时,要注意水温是在常温水的状态下。如果没有出现膜层与纸张分离的状况,那么就说明覆膜非常的牢固。

  4: Put the coated paper in water for one to two hours, and pay attention to the water temperature in the normal temperature water. If there is no separation between the film and the paper, then the film is very strong.
