Abstract:
In a method to correct a registration error in a printing process, data of first and second images to be printed are subjected to a raster image process via which at least first and second raster graphics are generated. Control data for a print member or two respective print members are formed from the first and the second raster graphics. A recording medium is printed in a first printing process with the control data of the first image. The recording medium is subjected to a treatment via which the recording medium and the first image deform along at least one deformation axis. The recording medium is printed by the print member with the control data of the second image in a second printing process. To avoid a registration error between the first and second printed images, the control data of the respective raster graphic of at least one of the first and the second print images as a source image are processed 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.
