To print the calibration swatch:
If you use a strip device such as the Gretag-MacBeth EyeOne, you may get invalid readings for the white data. To ensure that you get usable spot data points for each measurement, you will need to use the data from the black channel. To do this, click on Setup in the Print Swatch Dialog. In the Swatch Options tab, click select Spot 1 to substitute with the black linearization information.
