Abstract:
1. A method to correct a registration error in a printing process, comprising the steps of: subjecting data of first and second images to be printed to a respective raster image process via which at least first and second respective raster graphics structured in rows and columns are generated; forming control data for a print member or two respective print members from the first raster graphic and the second raster graphic; printing a recording medium in a first printing process with the control data of the first image; subjecting the recording medium to a treatment via which said recording medium and the first image deform by a deformation factor at least along one deformation axis; printing the recording medium in a second printing process with the control data of said second image; and to avoid a registration error between the first and the second printed images, processing the control data of the respective raster graphic of at least one of the first and second print images as a source image along an image processing axis of the respective raster graphic that corresponds to the deformation axis and wherein respective source pixels to be used for the respective raster graphic are selected stochastically from the source image in a direction transverse to the image processing axis.
