Abstract

The embodiment of the invention discloses a method and device for compensating an abnormal nozzle by adjusting prepress data, equipment and a medium. The method comprises the steps that position information of the abnormal nozzle in nozzles is determined; a printing parameter is obtained, and the mapping relation between the abnormal nozzle position and to-be-printed data of original printing datafiles is determined; a compensation printed data range used for compensating the abnormal to-be-printed data corresponding to the abnormal nozzle is obtained according to the mapping relation and theposition information of the abnormal nozzle; non-ink-discharging data are determined within the compensation printed data range; and the non-ink-discharging data are replaced with the abnormal to-be-printed data to generate compensation printed data. Through the technical scheme, the printed data of the abnormal nozzle are effectively compensated, and the quality of a printed image is improved.

Description

technical field [0001] The invention relates to the technical field of inkjet printing, in particular to a method, device, equipment and medium for adjusting pre-press data compensation for abnormal nozzles. Background technique [0002] Inkjet printing refers to spraying ink droplets onto the printing medium through the nozzles on the nozzle to obtain images or text. Reciprocating scanning printing technology is a commonly used technology in the field of inkjet printing at present. 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 before printing can be completed. , each unit is composed of multiple pixels, such as 2pass scanning and printing, each unit is composed of 2 pixels, and 3pass scanning and printing, each unit is composed of 3 pixels. Such as figure 1 It is the principle diagram of 4pass scanning and printing. A certain ...
