Many times, we need to do a lot of processing on the printing of instructions to make the instructions read more in line with customers' reading habits. Colleagues also let customers like to know our products better. Today, we will explain the printing process of instructions to everyone. What is the over gloss glue and over dumb glue?

過光膠，過啞膠又俗稱為過光膜過啞膜。它的原理是把一種專用的塑料膜涂上特定的膠水再加熱加壓和紙張粘合在一起，后形成的產品就是過了光膜或者啞膜的了

Glazing glue and matt glue are also commonly known as glazing film and matt film. Its principle is that a special plastic film is coated with specific glue, then heated and pressed to bond with the paper, and the product formed is beyond the light film or the dumb film

那么知道了原理我們再來說說印刷說明書時什么情況下才會用，他們又有什么區別，有什么效果。

Now that we know the principle, let's talk about when the manual will be used when it is printed, what are the differences between them, and what are the effects.

先說他們的效果。過了光膜和啞膜的紙由于上面多了一層塑料膜，所以比沒過的摸起來手感要光滑，要厚些，硬些，而且不容易撕爛。所以不管從品質上，外觀上來說都要比沒過的不少。辨別的方式是可以吧紙張撕開一個小口，有過膜的上面就會與一層膜，（如下圖）

Let's talk about their effects first. The paper that has passed the gloss film and matt film has a layer of plastic film on it, so it feels smoother, thicker, harder, and is not easy to tear. So no matter in terms of quality and appearance, it is much better than before. The way to distinguish is to tear a small opening on the paper, and the top of the paper with film will be connected with a layer of film, as shown in the following figure

那么它們又有什么區別呢？

What's the difference between them?

過光膜出來的產品表面會反光，特別亮

The product surface coming out of the light passing film will reflect light, especially bright

而過啞膜的產品摸起來稍微沒那么光滑，表面不會反光發亮，顯得更深沉一點。不過啞膠要比過光膠稍微貴一點點

The products that have passed the dummy film are slightly less smooth to the touch, and the surface will not reflect light, which makes them appear more profound. However, dumb glue is a little more expensive than polished glue

根據我們過往的經驗，發現在很早之有比較多的客戶要求過光膜，但是漸漸的大家都覺得太亮顯的俗氣，所以現在過啞膜的相對要多，大家覺得過啞膜顯得深沉一些。

According to our past experience, we found that in the early days, many customers asked for optical film, but gradually everyone felt that it was too bright and tacky, so now there are relatively many people who have passed the dumb film, and everyone thinks that the dumb film looks deeper.

下面再說說一般什么情況下使用。

Now let's talk about the general conditions.

既然過出來的紙張又厚又硬，肯定不適合在內頁，所以一般是封面才用，而且普通的產品說明書用的都比較少。一般是比較的，客戶要求比較高的，才會使用。因為使用這個工藝會使每一本產品說明書的成本多出2毛左右。具體跟印刷數量，是單面過膠還是雙面過膠等因素相關。而使用的比較多的產品就是畫冊，產品目錄等彩色印刷的印刷品。

Since the paper is thick and hard, it is definitely not suitable for the inside page, so it is usually used for the cover, and the general product instructions are used less. Generally, they are relatively good. Only those with high customer requirements can be used. Because using this process will make the cost of each product manual about 20 cents more. The specific price is related to the printing quantity, whether it is single-sided or double-sided. The products that are used more are color printed prints such as picture albums and product catalogs.

當然，黑白的使用的也不少，具體用不用還要看客戶自己的定位，如果想要看起來一點，就過一下。

Of course, there are a lot of black and white products. Whether they are used or not depends on the customer's own positioning. If you want to look a little better, just go through it.
