Liquid discharge apparatus and liquid discharge method
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.
