Abstract
A liquid ejecting apparatus includes a liquid ejecting head that has an ejection surface including a first nozzle row configured to eject a first ink and a second nozzle row configured to eject a second ink. The liquid ejecting head is configured to be held in a first posture in which the ejection surface is inclined with respect to a horizontal plane. A dynamic surface tension of the second ink is higher than a dynamic surface tension of the first ink. In the first posture, the first nozzle row is positioned above the second nozzle row with respect to a gravity direction.
Claims18
A liquid ejecting apparatus comprising:
- a liquid ejecting head that has an ejection surface including a first nozzle row configured to eject a first ink and a second nozzle row configured to eject a second ink, wherein
- the liquid ejecting head is configured to be held in a first posture in which the ejection surface is inclined with respect to a horizontal plane,
- a dynamic surface tension of the second ink is higher than a dynamic surface tension of the first ink, and
- in the first posture, the first nozzle row is positioned above the second nozzle row with respect to a gravity direction.
A liquid ejecting apparatus comprising:
- a first liquid ejecting head that has a first ejection surface including a first nozzle configured to eject a first ink;
- and
- a second liquid ejecting head that has a second ejection surface including a second nozzle configured to eject a second ink, wherein
- a dynamic surface tension of the second ink is higher than a dynamic surface tension of the first ink,
- the first ejection surface is disposed such that an angle formed by an ejection direction of the first ink ejected from the first nozzle and a gravity direction is a first angle, and
- the second ejection surface is disposed such that an angle formed by an ejection direction of the second ink ejected from the second nozzle and the gravity direction is a second angle larger than the first angle.
A liquid ejecting head comprising:
- a first nozzle row configured to eject a first ink;
- a second nozzle row configured to eject a second ink;
- and
- a third nozzle row configured to eject a third ink, wherein
- a dynamic surface tension of the third ink is higher than a dynamic surface tension of the first ink and is lower than a dynamic surface tension of the second ink, and
- the third nozzle row is positioned between the first nozzle row and the second nozzle row.
