Method and device for improving pass number and color block uniformity and storage medium

The invention discloses a method and equipment for improving pass number and color block uniformity and a storage medium. Comprising the steps that S1, the number of effective output holes of a spray head is confirmed; S2, the pass number is converted according to the resolution ratio and the transverse and longitudinal printing resolution ratio of the spray head; S3, the printing rule is carried out according to prn data; according to the method, the template A and the template B which are complementary are generated, and the AND operation is performed according to the printing data rule, so that regular white lines caused by needle breakage and inclined spraying of a spray head can be avoided, and in each pass, the AND operation is performed according to the template and the printing data, so that the white line part is correctly filled with colors, and the regular white lines are eliminated; and the dynamically-adjusted template can monitor the printing quality and the color block uniformity in real time a
