A thin film device, which can maintain desirable performance characteristics by reducing parasitic capacitance and increasing the Q factor even when a thin film coil of a solenoid type is equipped, is provided. Three-parallel processing is performed by elements of the system. Correcting values necessary for the automatic control of the printing operation can be determined on the basis of the information thus obtained, which can be also be continuously acquired due to the space-optimized tone value andor color gradients.
