Abstract: A liquid discharge apparatus includes a liquid discharger, a curing device, a multi-scanning device, and processing circuitry. The multi-scanning device causes the discharger to relatively scan a non-permeable recording medium multiple times in each of two intersecting directions to form an image that includes pixels with different discharge amounts of an active energy ray curable liquid in a region of the medium. The circuitry generates thinned image data for forming the image for each relative scanning in a first direction, using a mask in which pixels allowing image formation are arrayed. The circuitry generates the thinned data such that a spatial frequency of an array of the pixels allowing image formation in the mask for a first discharge amount is uniform in relative scanning in a second direction and the spatial frequency for a second discharge amount decreases toward a downstream side in the relative scanning in the second direction.
