Abstract: A graphics adaptation method for printable ceramic supports. Images are printed on sample ceramic supports starting from an original image file. A sample printed image is acquired. Sample points representative of the sample image are selected. Original points present in the original image file are also selected. A point-based matching is sought between the sample points and the original points, on the basis of which the original image file is modified and an adapted image file is determined, thus adapting the graphics of the original image file to the graphics of the sample image. A graphics adaptation system based on the method is also described.

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.

Abstract: A method for locating a printing substrate moving on a conveyor surface. The method includes i) providing the printing substrate moving on a conveyor surface at a selectable speed and in a feed direction, ii) providing an illumination means configured to emit a light beam incident on the conveyor surface according to a predetermined angle, iii) acquiring a predetermined plurality of lines of the substrate, as a function of a line frequency defined as a function of an acquisition rate, iv) generating a primary image as a function of the predetermined plurality of lines, v) detecting, from the primary image, points representative of the substrate, and vi) calculating location coordinates of the substrate relative to the first predefined reference as a function of the plurality of representative points.
