PURPOSE:To improve efficiency, to realize an invariably excellent setup without requiring any technique, and to produce a print copy of high quality stably, by using a color negative for condition setting, measuring the densities of the print copy of blue, green, and red, and setting reference copying condition according to the function of the actual measured values and measured values of a target print copy. CONSTITUTION:The print copy is set at a setting part 107 during setup, its quantities of transmitted light is measured by a photodetector 109, and the measured value is processed and stored by a central processing part and a numeric processing part 200. A color printer after the setup measures the quantities of transmitted light of a color negative through photodetectors 201-203, i.e. 109 for normal copying operation, and they are processed by the central processing part and numeric processing part 200 to send drive controlling signals to a shutter and cut filter driving part 213, i.e. 114 through a driving part interface 212, controlling exposure. |
