The invention relates to a method for obtaining spectral, densitometric or colour measured values on sheet-type materials to be printed (705) during the printing process in a sheet printing machine (1). The inventive method is characterised in that the measured values are determined on sheets (705) moving through the printing machine (1), and used by means of a computer (200) as control parameters for controlling the printing process of the sheet printing machine (1).
During the inline measurement of sheets to be printed during the printing process, measured value deviations are created in relation to external reference measurements on sheets in stable conditions. Said measured value errors are caused by the effects of the colour separation and by the drying effects of the sheet. In order to obtain colour measured values that are compatible with external reference measurements, said measured value errors are eliminated or corrected by a combination of measuring and calculating correction steps. The measured value correction is carried out on the basis of a model that describes the measured value error as a combination of three error contributions caused by the surface effect, the layer thickness modulation and the light trap. Three degrees of freedom quantified by three correction functions are introduced for the correction. Said correction functions are stored in a correction database as correction parameters, and a specific set of correction parameters is provided for each combination of environment parameters of the printing process in question. The inventive correction method enables the conversion of measured values between three states corresponding to direct measurement during the printing process, measurement on a printed sheet that is still wet, and measurement on a dried printed sheet.
