Abstract
A photographic reprint system utilizes an elongated paper tab to which film segments or strips are attached. Information relating to the printing of each film frame of the segments attached to the tab is stored sequentially in a storage medium such as a floppy disk. This information includes the selected color balance setup and a film size or format code indicating the size of the film segment. After the tab with attached film segments has been prepared, it is taken to a photographic printer, where the tab with the attached film segments is advanced sequentially and the negatives are printed. The printing is based upon information which is sequentially retrieved from the storage medium. Among the information contained in the selected color balance setup is a film size code indicating the size of film for which the color balance setup is used. The photographic printer compares the film size code from the selected color balance setup with the film size code retrieved from the storage medium. If the two film size codes do not correspond, this indicates an error condition, and operation of the printer is halted or other action consistent with automatic printer operation is taken.
