Abstract

The embodiment of the invention provides a method, a device, equipment and a medium for compensating an abnormal nozzle by changing data before printing. The method comprises the following steps of: determining the position information of the abnormal nozzle in a sprayer; acquiring printing parameters, and determining the mapping relationship between the nozzle position and the to-be-printed datain an original printing data file; acquiring a printing data compensation range for compensating the abnormal to-be-printed data corresponding to the abnormal nozzle according to the mapping relationship and the position information of the abnormal nozzle; determining non-inking data within the printing data compensation range; and replacing the non-inking data with the abnormal to-be-printed dataso as to generate compensated printing data. The method disclosed by the invention can be used for effectively compensating the printing data of the abnormal nozzle and improves the image printing quality.

Description

technical field [0001] The present invention relates to the technical field of inkjet printing, and in particular, to a method, device, device and medium for modifying pre-print data to compensate for abnormal nozzles. Background technique [0002] Inkjet printing refers to the jetting of ink droplets onto the print medium through nozzles on the printhead to obtain images or text. Reciprocating scanning printing technology is a commonly used technology in the field of inkjet printing. Reciprocating scanning printing is also called multi-pass scanning printing. Multi-pass scanning printing means that each unit of the image to be printed needs to be interpolated multiple times to complete the printing. , each unit is composed of multiple pixels, such as 2-pass scanning printing, each unit is composed of 2 pixels, and 3-pass scanning and printing, each unit is composed of 3 pixels. like figure 1 It is the principle diagram of 4pass scanning and printing. A certain area A (or ...
