A system comprising: a memory to store machine readable instructions; and a processing unit to access the memory and execute the machine readable instructions, the machine readable instructions comprising: a press color state estimator to: receive section measurement data characterizing a color measurement of multiple copies of a scanned section of a plurality of documents printed for the print job provided by a scanner, the scanned section of the plurality of documents including the same image for each of four single separation colors; calculate an optical density for each of the four single separation solid colors based on the color measurement, the color measurement characterizing material printed on a substrate and scanned by the scanner; calculate a color deviation for each of the four single separation colors based on the section measurement data; calculate an optical density drift of the scanner for each of four single separation solid colors based on the color deviation for each of the four single separation colors; and provide an updated LUT for each of the four single separation colors based on the color measurement provided by the scanner; and a print controller to provide the updated optical density for each of the four single separation solid colors and the updated LUT to a printer to facilitate color calibration of the printer. a memory to store machine readable instructions; and a processing unit to access the memory and execute the machine readable instructions, the machine readable instructions comprising: a press color state estimator to: receive section measurement data characterizing a color measurement of multiple copies of a scanned section of a plurality of documents printed for the print job provided by a scanner, the scanned section of the plurality of documents including the same image for each of four single separation colors; calculate an optical density for each of the four single separation solid colors based on the color measurement, the color measurement characterizing material printed on a substrate and scanned by the scanner; calculate a color deviation for each of the four single separation colors based on the section measurement data; calculate an optical density drift of the scanner for each of four single separation solid colors based on the color deviation for each of the four single separation colors; and provide an updated LUT for each of the four single separation colors based on the color measurement provided by the scanner; and a print controller to provide the updated optical density for each of the four single separation solid colors and the updated LUT to a printer to facilitate color calibration of the printer. receive section measurement data characterizing a color measurement of multiple copies of a scanned section of a plurality of documents printed for the print job provided by a scanner, the scanned section of the plurality of documents including the same image for each of four single separation colors; calculate an optical density for each of the four single separation solid colors based on the color measurement, the color measurement characterizing material printed on a substrate and scanned by the scanner; calculate a color deviation for each of the four single separation colors based on the section measurement data; calculate an optical density drift of the scanner for each of four single separation solid colors based on the color deviation for each of the four single separation colors; and provide an updated LUT for each of the four single separation colors based on the color measurement provided by the scanner; and a print controller to provide the updated optical density for each of the four single separation solid colors and the updated LUT to a printer to facilitate color calibration of the printer.
