一、食品包裝袋印刷要對滾筒壓力作恰當調整，包裝袋印刷時稍有不慎就會軋橡皮;假如是墨色過重、實底太大還容易粘橡皮或粘墨輥。因而，印刷前要減輕滾筒的壓力，橡皮內的包襯要減少。為了防止粘橡皮、軋橡皮，要向油墨內多加些添加劑或轍粘劑，同時看好，防止雙張、多張和紙張傾斜，確保壓力平均不軋橡皮。
First, the pressure of the drum should be adjusted properly in the printing of food packaging bags. If there is a slight carelessness in the printing of the packaging bags, the rubber will be rolled; if the ink color is too heavy and the solid bottom is too large, it is easy to stick the rubber or stick the ink roll. Therefore, the pressure of the drum should be reduced before printing, and the inner lining of the rubber should be reduced. In order to prevent rubber from sticking and rolling, some additives or rutting adhesives should be added to the ink. At the same time, it should be good to prevent double sheets, multiple sheets and paper from tilting, so as to ensure that the average pressure does not roll the rubber.
山通知您紙張和顏色普通客戶在做印刷品之前都會肯定用處，明白請求或者提供設計稿，這樣一來紙張和顏色方面根本就肯定了，那么要到達設計的請求或者滿足客戶的展現需求，印刷工藝就十分重要了:
Shan informs you that ordinary customers of paper and color will be sure of their use before making printed matter, understand the request or provide design manuscripts, so that the paper and color aspects are fundamentally affirmed, so in order to reach the design request or meet the customer's display needs, printing process is very important:
打孔：就是按請求按尺寸給一張紙或N張紙弄個洞出來，有特地的打孔機。
Punching: Punching a hole in a sheet of paper or N sheets of paper according to the size requested, with a special punch.
擊凸、壓紋：學名為壓印，靠壓力使承印物體產生部分變化構成圖案的工藝，是金屬版腐蝕后成為壓版和底版兩塊停止壓合。分為廉價的普通腐蝕版和昂貴的激光雕琢版兩種
Embossing and embossing: The technology of embossing, which relies on pressure to change part of the printed object to form a pattern, is that the metal plate becomes the embossing plate and the bottom plate stop pressing after being corroded. There are two kinds of cheap common etching plate and expensive laser engraving plate.
：就是彈簧一樣物體，塑料居多，普通用在掛歷和筆記本的書脊上，翻頁銜接用的。

Jin Cong: It is to put a layer of glue on the paper first and then sprinkle gold powder on the glue.
：就是紫外線，UV是簡稱，“UV透明油”才是全稱，就是靠紫外線映照才干枯燥固化油墨。UV通常是絲印工藝，如今也有膠印UV。
Ultraviolet, UV is abbreviated as "UV transparent oil" is the full name, that is to rely on ultraviolet light to dry dry curing ink. Usually UV is a screen printing process, but now there are offset UV.
過膠：給印好的紙張壓一層透明的塑料膠膜，有水晶膜、光膜和亞光膜，很多叫法有些不同，不。
Overgluing: Press a transparent plastic film on the printed paper, including crystal film, light film and matte film. Many central terms are somewhat different and not environmentally friendly.
針孔：也叫針線、牙線，就是給紙張壓出一道半銜接的線條，通常呈現在包裝啟齒處。
Pinhole: also known as needle thread, dental floss, is to press a semi-cohesive line to paper, usually presented at the opening of the packaging.
燙金：學名叫做熱壓轉移印刷，簡稱熱移印，俗稱燙金、燙銀。相對的還有個冷移印。
Gold stamping: The scientific name is hot press transfer printing, referred to as hot transfer printing, commonly known as gold stamping and silver stamping. There's also a cold offset.

印刷的三個要素是紙張，顏色，工藝。
The three elements of printing are paper, color and process.
紙張：紙張分類很多，普通分為涂布紙、非涂布紙。涂布紙普通指銅版紙(光銅)和啞粉紙(無光銅)，多用于彩色印刷；非涂布紙普通指膠版紙、新聞紙，多用于信紙、信封和報紙的印刷。
Paper: Paper can be classified into coated paper and non-coated paper. Coated paper generally refers to copper plate paper (smooth copper) and matte paper (matte copper), mostly used for color printing; non-coated paper refers to offset paper, newsprint, mostly used for letter paper, envelope and newspaper printing.
顏色：普通印刷品是由黃、品紅、青、黑四色壓印，另外還有印刷專色。
Colour: Ordinary printing is made of yellow, magenta, blue, black four-color impression, in addition to printing spot color.
后加工：后加工包括很多工藝，如過膠(覆膜)、過UV、過油、燙金、擊凸等，有助于進步印刷品層次。
Post-processing: Post-processing includes many processes, such as gluing (film coating), UV, oil, stamping, bumping and so on, which helps to improve the printing level.
