Abstract
During the processing of an order in a photographic printer, a developed copy film strip can be scanned negative by negative and point-by-point in a scanning station of the printer. From the scan signals, density values for exposure time determination in three partial colors and details on the image field number of the scanned negative can be obtained, and these data are stored in a memory, coordinating the determined three partial exposure times with the corresponding image number. All negatives of the copy film strip are exposed successively on photographic paper on an enlarged scale, using the determined exposure times. In a further step, a number of successive negatives of the film strip are exposed on full-scale or reduced scale in matrix form onto a single sheet of said photographic paper. The image field number associated with each negative is also exposed in matrix form on the single sheet and the exposure data stored from the initial scanning procedure are used as a basis for the exposure of the individual partial images. In addition to the exposures of the negatives, further data in connection with the film strip can also be exposed.
