Add a spot color by measuring a sample color
With the spot color measurement procedure, you measure three locations of a sample of the spot
color. The printer calculates and returns the average Lab value and reports a ΔE to indicate the
differences. The reported ΔE value is the largest difference between each individual measured
value and the average of all measured values. A ΔE larger than 3 means a large difference. In that
case you are advised to measure the spot color again.
