摘要： A liquid discharge apparatus includes a liquid discharge device, circuitry, and a curing device. The liquid discharge device is configured to discharge a liquid having a curing degree variable by a stimulation amount while relatively moving to a recording medium. The circuitry is configured to acquire surface roughness information indicating glossiness of a formed object formed on the recording medium and set a stimulation amount for the liquid based on the surface roughness information. The curing device is configured to stimulate the liquid discharged by the liquid discharge device based on the stimulation amount set by the circuitry to cure the liquid. The circuitry is configured to set, based on the surface roughness information, the stimulation amount for each region stimulated by the curing device in a same plane of the formed object.

摘要： Disclosed is an image forming apparatus that includes a recording head for forming an image by discharging single color ink from plural nozzle sequences. The image forming apparatus includes a profile generating unit configured to generate a profile including discharging characteristics of the corresponding nozzle sequences and information indicating a positional relationship among the plural nozzle sequences, based on individual images of a predetermined pattern that have been formed by the corresponding nozzle sequences and images that have been formed by the nozzle sequences; and a driving condition determination unit configured to determine drive conditions of the corresponding nozzle sequences by referring to the profile.

摘要： An image forming apparatus that performs correction to make gradation values adding both of two head areas (A+C, B+D) approximately equal. An area whose density is the lowest is set as a target density. Assuming densities for head areas A=70, B=100, C=40, D=90, head areas B and D are corrected with correction amount that ΔB become equal to ΔD (ΔB=ΔD=40) in accordance with target value (A+C=100).

摘要： A calculating unit calculates, as a reference number N of scans, a sum by adding 1 to a product M of the number m of scans in a main-scanning direction and the number n of scans in a sub-scanning direction. An assigning unit assigns, as a count of scans indicating a scan order, an integer 1 or more and the product M or more to each pixel of a unit image. A changing unit changes the count of scans of some pixels to which a first scan is assigned to an N-th scan. The generating unit generates print data, in which nozzle groups from a nozzle group arranged on a downstream end in the sub-scanning direction to a nozzle group arranged on an upstream end are sequentially assigned to pixels from the pixels to which the first scan is assigned to the pixels to which the N-th scan is assigned.
