Abstract:
1. A recording apparatus comprising: a recording head for performing recording on a recording medium by applying a recording material to the recording medium; a measurement unit configured to read a patch recorded on the recording medium including light emitting portion configured to emit light to the recording medium, and a light receiving portion configured to receive the light emitted by the light emitting portion and reflected by the recording medium by the recording head and to optically measure a density of the patch; an acquisition unit configured to acquire information indicating a spectral sensitivity of the measurement unit and information indicating a reference spectral sensitivity of a reference measurement unit including a light emitting characteristic of the reference measurement unit and a light receiving characteristic of the reference measurement unit; and a determination unit configured to determine an amount by which the recording material is to be applied from the recording head, based on the reading result of the patch measured by the measurement unit and the spectral sensitivity of the measurement unit indicated by the information acquired by the acquisition unit and the reference spectral sensitivity indicated by the information acquired by the acquisition unit.
