A liquid discharge apparatus includes a recording head and circuitry including a selective-discharge mask having two or more bits. The circuitry moves the recording head relative to a recording medium while causing the recording head to discharge a liquid onto the recording medium, moves the recording head and the recording medium relative to each other while causing the recording head not to discharge the liquid, alternately repeats a main scanning movement operation and a sub-scanning movement operation, converts input data to dot data including two or more types of dots, changes the selective-discharge mask in accordance with the types of the dots, converts the dot data to scan data for each of the main scanning movement operation using the dot data and the selective-discharge mask, and transfers the scan data to the recording head to cause the recording head to discharge the liquid according to the scan data.

Liquid discharge apparatus, liquid discharge method, and storage medium

A liquid discharge apparatus includes a color component divided data generation unit, a dot data generation processing unit, and a dot data segmentation processing unit. The color component divided data generation unit generates color component divided data from image data. The dot data generation processing unit applies a dot data generation mask to the color component divided data to generate dot data. The dot data segmentation processing unit applies a segmentation mask to the dot data to generate scan data. A width of the segmentation mask in a main scanning direction is different from a width of the dot data generation mask in the main scanning direction.
