1）制版工序是制造在印刷中起转移油墨到印材上作用的印版的过程。通过印版上制作的网点，再现原稿图像色彩。
1) the plate making process is the process of making plates that transfer ink to printing materials in printing. The color of the original image can be reproduced through the dots made on the plate.
2）印刷工序是使用承印物、印版、油墨、印刷机械实现图文复制的过程。即将印版上的图文转移到承印物上。按印版种类类分：凹版、柔性版、丝网版、凸版、平版印刷方式。
2) the printing process is the process of using substrate, plate, ink and printing machine to realize the reproduction of image and text. Transfer the image and text on the plate to the substrate. According to the type of printing plate: gravure, flexo, screen, relief, lithography.
我国软包装大多采用凹版印刷工艺生产，生产时，印刷材料经放卷装置放出进入印刷装置，印版表面的油墨被刮刀刮去，网点内的油墨在印材被压下发生接触时转移到印材上，之后进入烘箱内，油墨中的溶剂成分在加热、吹风的烘箱内挥发掉。印刷膜从烘箱出来后经过冷却辊式，降温定形。在多色印刷时，电脑自动套印装置控制各色间的套印。印刷完成后，收卷装置把印品卷取成卷状膜。
In China, soft packaging is mostly produced by gravure printing process. During production, the printing materials are discharged into the printing device through the unwinding device, the ink on the surface of the plate is scraped off by the scraper, and the ink in the dot is transferred to the printing material when it is pressed and contacted, and then it enters the oven, and the solvent components in the ink are evaporated in the oven heated and blown. After the printing film comes out of the oven, it is cooled and shaped by the cooling roller. In multi-color printing, the computer automatic overprint device controls the overprint between colors. After printing, the winding device rolls the printed matter into a roll like film.
