Calibration and Linearization
To print the calibration swatch:
Procedure
1. Click > Print Swatch and select a manual hand-held strip device or spot color sampling device and
click > Print.
NOTE
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.

2. Once the swatch is dry, click > Read Swatch and Read Swatch again to open the calibration data
table.
3. Follow the Strip letter and Patch number. If you have substituted the Black Channel for your white
ink there are no additional steps necessary.
4. Click > OK to accept readings and click > Next to continue.
5. Click > Build Linearization as usual. Note your Spot Channel curve is now represented bearing the
same curve as black. Continue on to the Ink Limits step.
