Abstract

The embodiment of the invention provides a printer nozzle abnormality compensation method, device and equipment and a storage medium. The printer nozzle abnormality compensation method comprises the steps that position information of an abnormal nozzle in a spray head is determined; printing parameters are obtained to determine a printing overlap area, and first print data corresponding to the printing overlap area is subjected to feathering treatment to obtain second print data; according to the position information of the abnormal nozzle and the printing parameters, first data correspondingto the abnormal nozzle is obtained from the second print data; the position information of a compensation nozzle corresponding to the first data which corresponds to a compensation abnormal nozzle inthe spray head is determined; second data corresponding to the compensation nozzle is obtained from the second print data when normal printing is performed, and the second print data includes inking data and non-inking data; and the first data is correspondingly written to an address of the non-inking data in the second data to generate compensation data. According to the technical scheme, the problem of poor image quality caused by abnormal inking of the abnormal nozzle is solved, and the maintenance cost of the spray head is reduced.

Description

technical field [0001] The invention relates to the technical field of inkjet printing, in particular to a printer nozzle abnormality compensation method, device, equipment and storage medium. Background technique [0002] Inkjet printing technology refers to the technology of spraying ink droplets onto the printing medium through the nozzles on the nozzle to obtain images or characters. One-time scanning printing technology is a commonly used technology in the field of inkjet printing at present. One-time scanning printing is also called single-pass scanning printing. Single-pass scanning printing means that each area of ​​the image to be printed only needs to be covered once to print. . like figure 1 It is the schematic diagram of single-pass scanning printing. The image to be printed is composed of n areas (or image blocks) of equal size, which are area A1, area A2, area A3... area An, and each area is composed of all nozzles on the nozzle once. Printing is complete; t...
