The multi-pass printing has low printing efficiency and low yield, but the price is low, so that the method is suitable for small-batch and intermittent production. The Onepass printing is that the length direction (X direction) of the nozzle array of the nozzle is vertical to the moving direction (Y direction) of the printing medium, the nozzle is generally fixed, the printing medium passes through the lower part of the nozzle once to obtain the pattern to be printed, and the printing medium moves continuously without pause. Oneeglass printing has the advantages of high efficiency and large output, and is suitable for a large-batch and continuous production mode.
