发明名称 Printing apparatus and method of printing using an ink jet method with respect to a medium
摘要 A printing apparatus in which printing is performed using an ink jet method includes a first ink jet head that discharges ink droplets of ink of a first color which is a color of the same color type as an expression color that is set in advance, a second ink jet head that discharges ink droplets of ink of a second color which is a color of the same color type as the expression color and is different from the first color, and a control unit which makes the first and the second ink jet head perform printing with the expression color on a medium by setting a ratio of a discharge amount of ink of the first color by the first ink jet head to a discharge amount of ink of the second color by the second ink jet head to a discharge rate which is calculated in advance.

主权项 1. A printing apparatus that performs printing using an ink jet method with respect to a medium, comprising: a first ink jet head that discharges ink droplets of ink of a first color which is a color of the same color type as an expression color which is a color that is set as a color to be expressed by printing in advance; a second ink jet head that discharges ink droplets of ink of a second color which is a color of the same color type as the expression color and is different from the first color; and a control unit that controls the discharge of ink droplets by each of the first ink jet head and the second ink jet head, wherein the control unit makes the first ink jet head and the second ink jet head perform printing with the expression color on the medium by setting a ratio of a discharge amount of discharging ink of the first color by the first ink jet head on the medium to a discharge amount of discharging ink of the second color by the second ink jet head on the medium to a discharge rate which is calculated in advance.
