Abstract

A liquid ejecting method is a liquid ejecting method of ejecting a liquid from a liquid ejecting head including a nozzle array constituted by arranging nozzles, in which the liquid ejecting head is configured to move relative to a first medium, the liquid ejecting method including ejecting, in a state in which the relative movement is stopped, a liquid from first nozzles constituting a part of the nozzle array to form a first liquid droplet on the first medium.

Claims (23)

1 . A liquid ejecting method of ejecting a liquid from a liquid ejecting head including a nozzle array constituted by arranging nozzles,

in which the liquid ejecting head is configured to move relative to a first medium,

the liquid ejecting method comprising:

ejecting, in a state in which the relative movement is stopped during a single stop, a liquid from each of a first plurality of nozzles to form a first liquid droplet on the first medium during the single stop.

2 . The liquid ejecting method according to claim 1 , wherein

the first plurality of nozzles constituting the part of the nozzle array are not adjacent to each other.

3 . The liquid ejecting method according to claim 2 , wherein

the number of the first plurality of nozzles is three or more, and

the number of times of ejection from the first nozzle that is not disposed at an end among the first plurality of nozzles for forming the first liquid droplet on the first medium is larger than the number of times of ejection from the first nozzle that is disposed at the end among the first plurality of nozzles.

4 . The liquid ejecting method according to claim 1 , wherein

the nozzle array includes a first nozzle group constituted by the first plurality of nozzles that are not adjacent to each other, and a second nozzle group that is different from the first nozzle group and is constituted by a second plurality of nozzles that are not adjacent to each other,

the liquid is ejected from the first plurality of nozzles constituting the first nozzle group to form the first liquid droplet on the first medium during the single stop, and

a liquid is ejected from the second plurality of nozzles constituting the second nozzle group to form a second liquid droplet on a second medium different from the first medium during the single stop.

5 . The liquid ejecting method according to claim 4 , wherein

the first plurality of nozzles and the second plurality of nozzles are arranged alternately.

6 . The liquid ejecting method according to claim 1 , wherein

the number of the first plurality of nozzles is three or more, and

the number of times of ejection from a first plurality of nozzle that is not disposed at an end among the first nozzles for forming the first liquid droplet on the first medium is larger than the number of times of ejection from a first nozzle that is disposed at the end among the first plurality of nozzles.

7 . The liquid ejecting method according to claim 1 , wherein

in a state in which the relative movement is stopped, the liquid is ejected multiple times from each of the first plurality of nozzles to form the first liquid droplet on the first medium.

8 . The liquid ejecting method according to claim 1 , the liquid being an adhesive.

9 . The liquid ejecting method accordance to claim 1 , the liquid being UV ink with resin.

10 . The liquid ejecting method accordance to claim 1 , all the first plurality of nozzles being linearly arranged.
