Abstract: An apparatus for discharging liquid includes at least three heads and control circuitry. The at least three heads are configured to discharge liquid and arranged at positions shifted in a second direction intersecting with a first direction. The control circuitry is configured to cause the at least three heads to scan in the first direction a number of times corresponding to an integral multiple of a number of the at least three heads to complete an image in a predetermined area.

Abstract: A liquid discharge apparatus includes a liquid discharge head, a scanning device, a storage device, and circuitry. The liquid discharge head discharges liquid from a plurality of nozzles onto a recording medium. The scanning device moves at least one of the recording medium and the liquid discharge head to perform scanning. The storage device stores a plurality of mask patterns to change a discharge amount and a discharge size of the liquid from the liquid discharge head. The circuitry acquires image data, creates dot data from the image data, and determines the discharge size of the liquid to be discharged from the liquid discharge head, based on the dot data and one of the plurality of mask patterns.

Abstract: An image forming apparatus includes: a droplet discharging head that includes nozzles; a light emitting unit that irradiates laser light emitted in a direction intersecting a discharging direction of a droplet discharged from each of the nozzles; a light-receiving unit that receives scattered light when the droplet is irradiated by the laser light and outputs a detection signal; and a droplet discharge detecting unit that detects a droplet discharging state of each of the nozzles based on the detection signal from the light-receiving unit. The light emitting unit emits the laser light such that intensity of the laser light gradually increases or decreases as the laser light travels farther, and the droplet discharge detecting unit selects nozzles so as to cause a variation in the detection signal depending on a droplet discharging state, and detects the droplet discharging state of the detection target nozzles based on the scattered light.

Abstract: 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.
