Abstract: Methods and systems methods calculate an initial matrix by correlating scanned test device-dependent values to device-independent color space values of a test sheet. The initial matrix converts device-dependent values to device-independent color space values; however, the initial matrix does include some conversion error. Such methods then calculate an inverse matrix from the initial matrix. These methods and systems then calculate target device-dependent values by applying the device-independent color space values to the inverse matrix. The methods and systems derive final one-dimensional look-up tables that isolate the conversion error by correlating the scanned test device-dependent values to the device-independent color space values. These methods and systems then derive a final matrix specific to the scanner by first applying the scanned test device-dependent values to the final one-dimensional look-up tables before creating the final matrix.
