Abstract
To predict more accurately whether ink dots formed on the surface of paper by two nozzles arranged in a nozzle row and located at positions close to each other overlap. A luminance amount for each unit area surrounding each chart is derived from scanned data obtained by reading results of printing a plurality of charts (two-dot line chart corresponding to a nozzle pair of a nozzle of interest and a neighboring nozzle thereof among the plurality of nozzles) associated with a plurality of nozzles respectively. Then, based on the luminance amount for each unit area, the dot formation state in a dot formation line by the plurality of nozzles is determined.
