9.7 Let the vector U0 contain the input patch gray levels (or area coverages) for controlling DEa*b from paper for magenta separation shown in Table 9.4. They are shown in the second column. In the third column, the vector, x, contain the normalized values transformed to gray levels of the DEa*b from paper measurements are shown. Use identity referenceTRCand direct inversion process. Process magenta separated image through the inverted TRC and printer model.
