Abstract

The invention discloses a method, device and equipment for adjusting an ink discharge amount to compensate for an abnormal nozzle, and a medium. The method comprises the following steps of acquiring the position information of the abnormal nozzle in a nozzle unit and the printing parameter of an image to be printed; according to the position information of the abnormal nozzle and the printing parameters, determining first printing data corresponding to the abnormal nozzle and position information of a compensation nozzle for compensating for the first printing data corresponding to the abnormal nozzle; according to the printing parameter and the position information of the compensation nozzle, determining second printing data corresponding to the compensation nozzle during normal printing;judging whether the ink discharging amount corresponding to the second printing data is smaller than the maximum ink discharging amount set by an ink jet printer; and if yes, adjusting the second printing data according to the first printing data to generate compensation data. According to the method, the quality of the image printed by the abnormal nozzle is improved, and the maintenance cost ofthe nozzle is reduced.

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 ink output and compensating 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. but if figure 1 As shown, after the nozzles of inkjet printers work for a long time, due to ink path pollution, ink precipitation, dust, water vapor and other reasons, it is easy to cause abnormal status of the nozzles of the nozzles, such as clogging, oblique spraying, voiding, insufficient ink, etc. , As a result, problems such as lines and blanks appear in the printed image, which seriously affects the quality of the product. [0003] When the state of the nozzle of the nozzle is abnormal, the common method is to clear the nozzle by cleaning, pressing ink and wiping. However, during the cleaning process, t...
