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.
