To suppress deterioration in colorimetry precision of a colorimetry section under an influence of heat of drying air from a drying section when a photographic processor sets up by itself.

A photographic print system 1 includes the drying section 60, a density measurement section 80, a light emitting diode 82, and a light propagation section 84. The light propagation section 84 is arranged to connect the density measurement section 80 to nearby a position irradiated with irradiation light from the light emitting diode 82 on a surface of a setup test print TP conveyed at the drying section 60, and propagates reflected light from the surface of the setup test print TP to the density measurement section 80. The reflected light from the irradiation position on the surface of the setup test print TP conveyed at the drying section 60 is propagated by the light propagation section 84 to the density measurement section 80 to measure density.
