Abstract: A method for rotating a digital image in order to print a corresponding rotated print image. The method includes i) providing the digital image to be printed on the printing substrate; ii) receiving positioning coordinates of the substrate relative to a first predefined reference; and iii) rotating the image relative to its centre as a function of the positioning coordinates, thus determining a rotated image. According to one aspect, the rotation is performed by means of a technique of mapping between pixels of the rotated image and pixels of the digital image, and calculating a matrix of correspondences between the pixels of the rotated image and the pixels of the digital image. According to another aspect, the matrix is configured to indicate how many pixels of the rotated image correspond to pixels of the digital image.
