  • Publication number: 20200349403
    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.

  • Patent number: 10699380
    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.
