Abstract

The invention belongs to the technical field of industrial inkjet printing, solves the technical problem in the prior art that the driving waveform of the nozzle does not meet the printing requirements, resulting in abnormal inkjet, and provides a method, device, equipment and storage medium for adjusting the driving waveform of the nozzle. The method includes: adjusting the pressurization rate and pulse duration of the initial driving waveform of the nozzle, obtaining the first driving waveform group, using the driving waveform of the first driving waveform group to perform test printing, obtaining a candidate driving waveform that meets the requirements, and adjusting the backup waveform. The fitting degree of the driving waveform is selected to obtain the second driving waveform group; the driving waveform of the second driving waveform group is used for test printing to obtain the target driving waveform. The present invention also includes devices, devices and storage media for performing the above methods. The invention can automatically calibrate the drive waveform of the nozzle when printing with different types of ink, so that the inkjet effect of the nozzle is the best, and the effect of printing images is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of industrial inkjet printing, and in particular, to a method, device, device and storage medium for adjusting the driving waveform of a nozzle. Background technique [0002] Piezoelectric inkjet technology is to arrange many tiny piezoelectric ceramics near the nozzle position of the print head of the printer. The two ends of the piezoelectric ceramic will bend and deform under the action of changing voltage, such as figure 1 , Figure 1a and Figure 1b As shown, the deformation amount of the piezoelectric ceramic will change with the voltage change across the piezoelectric ceramic, thereby causing the volume of the chamber in which the ink is stored in the nozzle to change. When the driving voltage is generated, the piezoelectric ceramic is deformed, and the volume of the ink chamber is reduced, but the nozzle is in the non-ejection position at this time; when the voltage is reduced, the piezoel...
