Abstract
In a method for producing photographic copies, first copies are produced in a first pass in a first printer, and any second copies needed are produced in a second pass by a second printer which is calibrated to the first printer by means of a setup test method. In this setup test method, the original-specific data ascertained in the first pass are delivered to a computing and control unit of the second printer. With the aid of these original-specific data and with the aid of an original model adapted to the copying material, the requisite quantities of copying light are ascertained in the computing and control unit of the second printer, and the second copies are made. The developed second copies are subjected to an analysis. Based on the analysis, the original model adapted to the copy material is optimized for the second printer until the second copies are substantially identical to the first copies.
