Not easy to learn. According to Zhihu, learning label printing machine requires two years of silk screen printing experience, one year of carton preprinting experience and two years of paper cup soft printing experience. We can start with the assistant. Whether it is a labeling machine or a rotary machine, the difficulty lies in manual color matching, which requires long-term study and practice. Printing machinery is the general name of auxiliary machinery and equipment such as printing machine, binding machine and plate making machine. These mechanical devices have different performances and uses, so their mechanical forms are not exactly the same.
