Abstract: The present invention generally relates to a method for variable data printing. A data set of compressed data is provided. The data set corresponds to a basic image layout comprising a plurality of dots. Using at least one general purpose computation on graphics processing unit the compressed data is decompressed to obtain decompressed data corresponding to the basic image layout. To each dot of the plurality of dots of the basic image layout a color value is assigned based on a reference entry of a color lookup table such that a decompressed first customized image layout to be printed is obtained. The decompressed first customized image layout is provided to at least one printer device. At least the decompressed first customized image layout is printed. The at least one printer device continuously prints subsequent decompressed customized image layouts at a predefined minimum printing speed.

Abstract: A method for fine adjustment of the position of ink drops printed by at least one printing head (12) of a printing device, the printing head (12) being a two-dimensional printing head (12) comprising a plurality of nozzles (30). In one method step, an ink drop is dispensed at a plurality of nozzles (30) of the at least one printing head (12) simultaneously to print an image, preferably at all nozzles (30) of the printing head (12). In another method step, the printed image is captured by a camera (20), wherein the camera (20) captures the pattern of dots printed by the printing head (12) and the captured pattern is compared to a pattern (36) of the nozzles (30) of the printing head (12). In a further method step, the dispensation of an ink drop from at least one nozzle (30) is modified in terms of timing with respect to the dispense of ink drops from the other nozzles (30) of the printing head (12) for the subsequent printing process if a deviation has been detected between the pattern (36) of dots printed by the printing head (12) and the nozzle pattern (36). Furthermore, a printing device is provided.
