A density determination method includes a first process, a second process, and a third process. In the first process, ink is discharged onto a medium to print a plurality of colorimetric patches having mutually different densities on the medium so as to allow each of the colorimetric patches to include a base portion serving as a background of the each of the colorimetric patches and a low density portion forming a symbol and having a density lower than a density of the base portion. In the second process, images each associated with a corresponding one of the colorimetric patches are acquired. In the third process, a maximum printing density value for the medium is determined on the basis of a result of recognizing the symbol through each of the images, having been acquired in the second process.
