A computer implemented graphic adaptation method of images for sample ceramic supports (PCS_j), wherein said ceramic supports (PCS_j) are adapted to receive a print, wherein the method comprises the steps of: - loading an original image file (F_PRINT) representing an image for printing (I_PRINT) comprising a graphic to be printed on a plurality of ceramic supports (PC_i)), wherein said image for printing (I_PRINT) is graphically defined in terms of first identifying graphic characteristics (GRAF_1) comprising one or more from among: - an original value of colour rendering (RC_1), wherein said colour rendering is the colour assumed by each point of the image, expressed in a known colorimetric system such as RGB or HSL; - a resolution (RS_1); - a reference perspective (PR_1); - printing a plurality of images on said sample ceramic supports (PCS_j) starting from said original image file (F_PRINT); - acquiring, through an image acquisition device, a sample image (IM_PCS_j) of said plurality of images printed on said sample ceramic supports (PCS_j), wherein said sample image (IM_PCS_j) is graphically defined in terms of second identifying graphic characteristics (GRAF_2) depending on said image acquisition device, wherein said second identifying graphic characteristics (GRAF_2) comprise one or more from among: - a sample value of colour rendering (RC_2), wherein said colour rendering is the colour assumed by each point of the image, expressed in a known colorimetric system such as RGB or HSL; - a sample resolution RS_2; - a second reference perspective PR_2; - selecting sample points representative of said sample image (IM_PCS_j), and selecting original points present in the original image for printing (I_PRINT), (f4.1) seeking a point based matching between said sample points representative of said sample image (IM_PCS_j),and said original points present in said original image for printing (I_PRINT); wherein said step (f4.1) of seeking a point based matching comprises seeking a spatial and colour point based matching between the sample points P2, representative of the sample image IM_PCS_j, and original points P1 present in the original image for printing (I_PRINT); - modifying said original image file (F_PRINT) starting from said point based matching determining an adapted image file (F_ADAPT), thus adapting the graphic of the original image for printing (I_PRINT) to the graphic of the sample image (IM_PCS_j). - loading an original image file (F_PRINT) representing an image for printing (I_PRINT) comprising a graphic to be printed on a plurality of ceramic supports (PC_i)), wherein said image for printing (I_PRINT) is graphically defined in terms of first identifying graphic characteristics (GRAF_1) comprising one or more from among: - an original value of colour rendering (RC_1), wherein said colour rendering is the colour assumed by each point of the image, expressed in a known colorimetric system such as RGB or HSL; - a resolution (RS_1); - a reference perspective (PR_1); - printing a plurality of images on said sample ceramic supports (PCS_j) starting from said original image file (F_PRINT); - acquiring, through an image acquisition device, a sample image (IM_PCS_j) of said plurality of images printed on said sample ceramic supports (PCS_j), wherein said sample image (IM_PCS_j) is graphically defined in terms of second identifying graphic characteristics (GRAF_2) depending on said image acquisition device, - an original value of colour rendering (RC_1), wherein said colour rendering is the colour assumed by each point of the image, expressed in a known colorimetric system such as RGB or HSL; - a resolution (RS_1); - a reference perspective (PR_1); - printing a plurality of images on said sample ceramic supports (PCS_j) starting from said original image file (F_PRINT); - acquiring, through an image acquisition device, a sample image (IM_PCS_j) of said plurality of images printed on said sample ceramic supports (PCS_j), wherein said sample image (IM_PCS_j) is graphically defined in terms of second identifying graphic characteristics (GRAF_2) depending on said image acquisition device, wherein said second identifying graphic characteristics (GRAF_2) comprise one or more from among: - a sample value of colour rendering (RC_2), wherein said colour rendering is the colour assumed by each point of the image, expressed in a known colorimetric system such as RGB or HSL; - a sample resolution RS_2; - a second reference perspective PR_2; - selecting sample points representative of said sample image (IM_PCS_j), and selecting original points present in the original image for printing (I_PRINT), (f4.1) seeking a point based matching between said sample points representative of said sample image (IM_PCS_j),and said original points present in said original image for printing (I_PRINT); - a sample value of colour rendering (RC_2), wherein said colour rendering is the colour assumed by each point of the image, expressed in a known colorimetric system such as RGB or HSL; - a sample resolution RS_2; - a second reference perspective PR_2; - selecting sample points representative of said sample image (IM_PCS_j), and selecting original points present in the original image for printing (I_PRINT), (f4.1) seeking a point based matching between said sample points representative of said sample image (IM_PCS_j),and said original points present in said original image for printing (I_PRINT); - modifying said original image file (F_PRINT) starting from said point based matching determining an adapted image file (F_ADAPT), thus adapting the graphic of the original image for printing (I_PRINT) to the graphic of the sample image (IM_PCS_j).
