Abstract
A method and a measuring device are proposed for controlling the color application of a printing press () using at least one ink-feeding device () on the basis of spectral reflectance values of printed surface elements () on a print substrate (), which are distinguished in that measured spectral reflectance values are converted into corrected spectral reflectance values. The method and/or the measuring device can be advantageously used in a printing system having a printing press (), to implement a control on the basis of polarized spectral reflectance values, in particular for a detector () which measures unpolarized spectral reflectance values.
