Zusammenfassung:	A method for reducing artefacts in printed objects comprises receiving print data to be printed by a printhead arrangement, the printhead arrangement being movable in a print direction and comprising a plurality of printhead dies, wherein printhead dies adjacent to each other comprise an overlap area when viewed in the print direction. The print data to be printed are modified near and/or at the overlap areas between printhead dies of the printhead arrangement to compensate for drop placement. Cette invention concerne un procédé permettant de réduire les artefacts dans des objets imprimés, comprenant l'étape consistant à recevoir des données d'impression à imprimer par un agencement de tête d'impression, l'agencement de tête d'impression étant mobile dans une direction d'impression et comprenant une pluralité de matrices de tête d'impression, les matrices de tête d'impression adjacentes comprenant une zone de chevauchement lorsqu'elles sont vues dans la direction d'impression. Les données d'impression à imprimer sont modifiées à proximité et/ou dans les zones de chevauchement entre matrices de tête d'impression de l'agencement de tête d'impression pour compenser le placement de gouttelettes.
