Printing apparatus and printing method |
摘要 |
A printing apparatus includes (A) a head that discharges first ink and second ink having a color different from that of the first ink, (B) an optical sensor that includes a light source and a light receiving section, and (C) a controller. In the printing apparatus, when the controller corrects a discharge amount of the second ink, the controller causes the head to discharge the first ink to form a first pattern on a medium, causes the optical sensor to detect light reflected from the first pattern, causes the head to discharge the second ink to form a plurality of second patterns having different gradation values on the first pattern, and causes the optical sensor to detect light reflected from the second pattern. |

1. A printing apparatus comprising:
(A) a head that discharges first ink and second ink having a color different from that of the first ink; (B) an optical sensor that includes a light source and a light receiving section; and (C) a controller, wherein in a case in which the controller corrects a discharge amount of the second ink, the controller causes the head to discharge the first ink to form a first pattern on a medium, the controller causes the optical sensor to detect light reflected from the first pattern, the controller causes the head to discharge the second ink to form a plurality of second patterns having different gradation values on the first pattern, and the controller causes the optical sensor to detect light reflected from the second pattern, wherein the controller changes the optical density of the first pattern depending on the type of the medium. |
