在印刷行业中，压缩空气的应用可基本覆盖整个印刷过程，如切纸、印刷、印后都有压缩空气的身影，在印刷企业进行空压机选型时需要确定这些设备的用气量，一般切纸机的用气量可以忽略不计，印刷机要看是单色、双色、四色或更多色机型，需根据印刷机的实际情况确定需要的气量，印后设备也有一定的用气量，不同的印后设备的用气量也会有所差别，印刷机在印刷时，用气元件一般都在运动，如吹纸和真空发生器的动作，印后设备一般气缸的使用较多，气缸动作最频繁，是耗气较多的原件。
In the printing industry, the application of compressed air can basically cover the whole printing process, such as paper cutting, printing and printing after the image of compressed air. In the selection of air compressors in printing enterprises, it is necessary to determine the air consumption of these equipment. Generally, the air consumption of paper cutting machines can be neglected. Printers should be monochrome, bichrome and double-color. Four or more color machines need to determine the amount of air needed according to the actual situation of the printing press. There is also a certain amount of air used in the post-press equipment. The amount of air used in different post-press equipment will also vary. When printing, the gas components are generally moving, such as the action of paper blowing and vacuum generator, and the general cylinder of post-press equipment. More use, cylinder action is the most frequent, is the more air-consuming original.
