[0003] In inkjet p...

AI Technical Summary

Problems solved by technology

In the process of inkjet printing, if the control accuracy of the ink path is not high or unstable, the printing quality of the printed pattern will cause defects such as dripping ink, uneven ink droplets, missing printing, etc., and even cause serious consequences of nozzle blockage and damage. Therefore, It is very important to develop an inkjet printing multi-nozzle ink path air pressure control system
