一、食品包装袋印刷要对滚筒压力作恰当调整，包装袋印刷时稍有不慎就会轧橡皮;假如是墨色过重、实底太大还容易粘橡皮或粘墨辊。因而，印刷前要减轻滚筒的压力，橡皮内的包衬要减少。为了防止粘橡皮、轧橡皮，要向油墨内多加些添加剂或辙粘剂，同时看好，防止双张、多张和纸张倾斜，确保压力平均不轧橡皮。
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.
山通知您纸张和颜色普通客户在做印刷品之前都会肯定用处，明白请求或者提供设计稿，这样一来纸张和颜色方面根本就肯定了，那么要到达设计的请求或者满足客户的展现需求，印刷工艺就十分重要了:
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:

Colour: Ordinary printing is made of yellow, magenta, blue, black four-color impression, in addition to printing spot color.
后加工：后加工包括很多工艺，如过胶(覆膜)、过UV、过油、烫金、击凸等，有助于进步印刷品层次。
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.
