Abstract
A liquid discharge apparatus includes: a liquid discharge head configured to discharge a liquid onto a printing medium to form an image on the printing medium; a conveyor configured to convey the printing medium to the liquid discharge head in a conveyance direction; a carriage mounting the liquid discharge head, the carriage configured to move the liquid discharge head in a first direction orthogonal to the conveyance direction; and a controller configured to calculate a control parameter to shift a printing position of the liquid discharge head in at least one of the first direction or the conveyance direction for each time the conveyor conveying the printing medium.
Claims6
1:
- A liquid discharge apparatus comprising:
- a liquid discharge head configured to discharge a liquid onto a printing medium to form an image on the printing medium;
- a conveyor configured to convey the printing medium to the liquid discharge head in a conveyance direction;
- a carriage mounting the liquid discharge head, the carriage configured to move the liquid discharge head in a first direction orthogonal to the conveyance direction;
- and
- circuitry configured to calculate a control parameter to shift a printing position of the liquid discharge head in at least one of the first direction or the conveyance direction for each time the conveyor conveying the printing medium.
2:
- The liquid discharge apparatus according to claim 1,
- wherein the conveyor includes:
- a stage onto which the printing medium is placed;
- and
- a rail extending in the conveyance direction in which the stage is moved, and
- wherein the circuitry calculates the control parameter to move the printing position in at least one of the first direction or the conveyance direction to adjust orthogonality between the first direction and the conveyance direction for each time the conveyor conveying the printing medium.
3:
- The liquid discharge apparatus according to claim 1, wherein the circuitry calculates the control parameter to shift the printing position of the liquid discharge head in the first direction stepwise for each line feed of the printing medium by the conveyor.
4:
- The liquid discharge apparatus according to claim 1, wherein the carriage includes multiple carriages.
5:
- The liquid discharge apparatus according to claim 4, wherein the circuitry calculates the control parameter for each of the multiple carriages.
6:
- The liquid discharge apparatus according to claim 1,
- wherein the liquid discharge head prints an adjustment image indicating a conveyance position of the printing medium.
