A liquid discharge apparatus includes a liquid discharge head and processing circuitry. The liquid discharge head is configured to discharge, to a foamable medium, liquid having a function of suppressing foaming of the medium to form irregularities. The processing circuitry is configured to hold condition information indicating a content defined by each of a plurality of conditions related to image formation at a time when the liquid forms a predetermined pattern image on the medium; and generate and output, for each condition of the plurality of conditions, an evaluation medium on which irregularities corresponding to the predetermined pattern image formed according to the condition are formed.
