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.

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;
- circuitry configured to measure an amount of deviation in a main scanning direction of lines which are adjacent to each other;
- and
- circuitry configured to calculate, using the amount of deviation that has been measured, 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 each time the conveyor conveying the printing medium.
