Abstract

A method for color control in printing presses having at least one first color measuring instrument and at least one second color measuring instrument, includes registering at least one first inking zone on a printing material with the first color measuring instrument and registering at least one other, second inking zone on the printing material with the second color measuring instrument. In a first step, a color difference between actual colorations of the first and second inking zones is calculated, in a second step, a color difference between an actual coloration of the first inking zone and a desired coloration of the second inking zone is calculated and, in a further step, the calculated color differences are added and supplied to a color control for the second inking zone.
