Spot colors realize a consistent color and are often used in logos and house style colors.
Below you find the instructions for creating a spot color on the control panel.
Touch
.To find a spot color, touch the [Search] button and enter a search string.

Touch [OK].
The spot color definition is stored in the custom spot color library.
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 ∆E to indicate the differences. The reported ∆E value is the largest difference between each individual measured value and the average of all measured values. A ∆E larger than 3 means a large difference. In that case you are advised to measure the spot color again.
Press [Add].
Select [CIELAB].
Enter the [L*], [a*], and [b*] values in the [Lab] setting.
