Example when the graph does not form a straight line
In the data and graph below, the data was obtained by using the Kodak MLP 190 to print
out the SMPTE test image, and the image data was measured.
(1): Shows normal data.
(2): Shows the case when the CXDI printer parameters are not set linearly.
(3): Shows the case when the printer was not calibrated properly.
