An information processing device that transmits print data to a printing apparatus includes a storage unit that stores combination information configured to identify a combination of a color of a print medium and a color of a color material and an adaptive density range that is a range of print densities suitable for reading a code image, a print combination information acquisition unit that acquires print combination information configured to identify a combination of a color of the print medium and a color of the color material, a density setting value acquisition unit that acquires a density setting value, a density determination unit that determines, whether the density setting value is included in the adaptive density range stored in association with the combination information same as the print combination information, and a density change unit that changes a print density of the print data.
