Abstract: In a method for calibrating a photographic copy printer, developed copies are scanned regionally (such as dotwise), and the measured light transmitted or remitted by each scanned region of the copying material is supplied to a detector array, broken down spectrally, and converted into wavelength- and intensity-dependent measurement data. The electrical measurement signals are digitized, and with their aid, copy-specific measurement data are ascertained. On the basis of the copy-specific measurement data, the original-specific measurement data, and the exposure used in the copying, a model of the original adapted to the copy material and a model for the copy material, or the model (Pi) inverse to it, which forms the basis for calculating the requisite amounts of copying light, are checked with respect to specifiable accuracy criteria and optimized as needed.
