  • Publication number: 20190275790
    Abstract: Provided is a printing method for forming ink dots on a printing medium by using a plurality of nozzle rows that discharge a plurality of types of photocurable inks. The printing method includes detecting a defective nozzle that has an ink discharge fault, and compensating for dot omission by causing, preceding the defective nozzle, a preceding nozzle that discharges an inducing ink different from a compensation target ink, which the defective nozzle should have discharged, to discharge the inducing ink to a position on the printing medium where dot omission occur due to the defective nozzle.
