If you have a spot color with different gradients and find that one gradient is too bright or too pale in the printout, you can modify the brightness by adding or subtracting color along the gradation curve.
You can modify a gradation point along the curve by dragging the point upward (to add color), or downward (to subtract color). You can also type the required coordinates directly in the table.
Preferences dialog box only: You can apply your changes to the current spot color table, or to all the future spot color tables you create.
You can delete a gradient by selecting a row in the table and pressing <Del>.
