How to Overprint Spot Data in Illustrator

Set Up Overprint
By default, when you print opaque, overlapping colors, the top color
knocks out (cuts a hole) in the area of colored image underneath.
Overprinting prevents knockout and allows the colored image data to print
over top of the other color being used, which in this case is white. You will
want to overprint when the artwork needs to be printed over top of white,
usually if the substrate material is non-white and therefore white is
required to accurately render image data.
Procedure
1.
Select the spot data object or objects that you want to overprint and place
these above the image data layer that you would like to print. Or if you
want them on the same layer the spot data objects should be in front of
the image data.
