Photographic printing method

摘要

In the prior art photographic printing systems, the correspondence between imaged frames of 135 type size film and printed sheets of photographic paper is not clearly made, which presents problems when a particular frame should be re-printed for make-over at the laboratory or for extraprints ordered by a customer as it is difficult to distinguish one frame from another in images. Even if frames are attached with numbers at a printing step, the frame number is hard to read with eyes. Frames different from the desired one are often printed for re-print to thereby waste time and photographic paper. This invention method enables correspondence of imaged frames of film with printed sheet of photographic paper by automatically obtaining identification information of printed frames based on the frame number and feeding direction which are initially set for each mounted film. This facilitates reference between printed sheets of photographic paper and imaged frames of an original film to thereby remarkably reduce mistakes in printing of extra prints or re-printing for make-over which might otherwise be caused by confusion of numbers.
