Patent ID: 8777354

Claim:
A printing method for a printing device which uses ink including pigment ink and dye ink to form a printed image on a print medium, and which discharges an ink quantity according to a voltage value of a drive voltage to form ink dots on the print medium, the method comprising: forming a first image on the print medium by using the printing device to perform a first ink dot creation process for forming pigment ink dots and then forming dye ink dots adjacent to the pigment ink dots; forming a second image on the print medium by using the printing device to perform a second ink dot creation process for forming dye ink dots and then forming pigment ink dots adjacent to the dye ink dots; measuring the respective concentrations of the first image and the second image by concentration measurement means; and correcting a voltage value of a drive voltage to create the pigment ink dots so that a difference between the concentration of the first image and the concentration of the second image is reduced, while maintaining a voltage value of a drive voltage to create the dye ink dots stationary.
