Abstract
Abstract The present invention relates to an automatic off-line photograph printing control system consisting of a reader and a printer. The system employs a magnetic or other similar recording means for storing correcting information of a negative film to be applied for automatically controlling printing works. Inspection and selection of each effective frame of the negative film at the stage of reading are usually performed through a projector (and a screen or through direct visual inspection of the negative film itself by the operator). Detection of effective frames of film at the stage of printing shall be carried out automatically with information marked on the negative film and information for adjustment of the exposure time supplied by the magnetic recording means upon printing. All the data concerning the negative film itself and others are processed in digital fashion.
