Referring to fig. 1-2, an embodiment of the present invention provides a technical solution: a jet printing method for high-speed jet printing of a piezoelectric nozzle specifically comprises the following steps:
s1, arranging dot matrix data of the jet printing images according to a piezoelectric nozzle rule, generating M rows by N columns of data in the XY direction by the images, and jet printing ndpi according to needs by the image generation module on the basis of a nozzle Ydpi to generate images and 1bit data in the X direction dpi, and simultaneously converting a jet printing mode 1bit into a 2bit driving mode;
s2, the image conversion module processes N/2dpi according to N column data in the direction of the Xdpi to generate new 2-bit jet printing image data, and the data conversion module converts 1-bit data into 2-bit data according to the ndpi image;
s3, the waveform driving module drives the nozzles to work through driving waveforms according to 2bit data, and performs twice jet printing actions on jet printing data of each row through adjustment of driving waveforms, the highest jet printing frequency of the nozzle is limited, such as the highest 50KHz, the driving control capacity of the control board card is far higher than that of the nozzle, and the jet printing speed is reduced when the jet printing resolution ratio of the nozzle in the paper feeding direction is higher;
and S4, the spray printing control module drives the spray head to spray print according to the converted data and waveform by using the spray printing frequency of n/2 dpi.
In the present invention, in step S1, the conversion is generated from different nozzles Ydpi, and the images generated by the different nozzles are different;
wherein n is the lowest jet printing dpi of the spray head and is an integer.
In the present invention, the image Ydpi data generated in step S1 is determined from the physical dpi of the inkjet printing without change;
where the number of columns, N and N, are integers and both N and N are greater than 1.
