The Setup screen is used to select the port for your device and calibrate your device.

When you click on Calibrate, the following screen will be displayed:
Make sure that the lens of the Spectrolino is directly over the white point reference, and click on the OK button. The window should then display the message: 'Calibration Complete'.

The Process Test Strips screen begins the strip reading process. To begin reading a strip, click on the button associated with the color you wish to read. Then follow the instructions presented in the message box directly below the Read Black Strip button. This interface is "hard-wired" to except the 17 data points used in the file 'dtp32.ps' which is located in your 'X:\psfiles' folder (X: being the letter of the drive on which Wasatch is installed). This is the only test pattern that will provide accurate results.
After the densitometer has returned the strip values, the 'Done' message will appear next to the color you selected. After each strip has been read, the Next button will change to Finish. You may select Finish after reading any number of the four strips to apply curves from only colors that you have measured. Colors that you did not measure will not be overwritten should curves already exist.
