Abstract
A photographic printing method and apparatus therefor having a pulse motor for transporting a photograhic film to place a picture frame in a printing position. In order to avoid an occurrence of cumulative position error, position data of each picture frame is provided in the form of a combination of the number of perforation holes and the number of driving pulses applied to the pulse motor while edges of each two adjacent perforation holes are detected. In a film inspection process, the position data is stored in a memory after having placing each picture frame in the printing position. The position data of each picture frame is read out in a printing process and compared with present position signals of the picture frame of the film being transported. Upon an occurrence of coincidence between the position data read out from the memory and the position data presently detected, the pulse motor is controlled to stop, thereby placing the picture frame in the same printing position as where the picture frame is placed in the inspection process.
