The resulting copying light is measured broken down by area, and the profile of the copying light is measured and compared with a desired copying light profile. Based on this comparison, the transmission profile preselected for the copying process is optimized.

Abstract: Prints of different formats are produced by pixel by pixel recording of image information available in digital form for each picture onto a carrier material from a group of band-shaped standard carrier materials having different preselected strip widths. The image information of a print is recorded in a normal orientation or rotated 90° when one of the dimensions of the print to be produced can be made to correspond with the strip width of the available carrier material. The carrier material is changed when neither the length nor the width of a print to be produced corresponds to the strip width of the available carrier material. For a set of pictures to be produced which have at least partially different formats, the sequence of the recording of the underlying picture information is set according to the formats of the prints to be produced so that the number of the required carrier material changes is minimized.
