Method for adjusting positive and negative overprinting of inkjet printing

The invention relates to the technical field of inkjet printing, in particular to a method for adjusting the positive and negative overprinting of inkjet printing. The method for adjusting the positive and negative overprinting of the inkjet printing comprises the following steps that step 1, a calibration and debugging stage is carried out, and the calibration and debugging stage comprises calibration and a spacing test; step 2, a verification stage is carried out; and step 3, an operation stage is carried out. According to the method for adjusting the positive and negative overprinting of the inkjet printing, a test pattern jet-printed on a printing stock is designed, the test pattern is judged by a machine vision system, a detection result is fed back to a jet-printing system, the jet-printing system performs self-adjustment according to the detection result to achieve the purpose of ensuring the positive and negative overprinting accuracy of the double-sided jet-printing system; and equipment related to t
