Method for efficient fan-out control

A printing method with fan-out control minimizes register deviations by using a computer. The method includes printing a test print including various color separations. The register deviations that have occurred relative to a reference color are measured. The absolute total of the register deviations of all color separations relative to one another is calculated. At least one color separation to be adapted is selected as a function of the calculated absolute total of all color separations. The at least one selected color separation is adapted. Finally, the register deviations that have occurred are compensates for by creating and using at least one printing plate for the adapted at least one color separation.
