Shadows not overprinting

[rande]

Are there any general rules to get shadows to trap.
We don't use Trap Editor.
Is there something in the trap settings to adjust that would take care of the shadows?
We received PDF:
a glow or slight drop shadow and when isolated its connected to the background which is a green,
10/0/49/28
measuring right on top of the darkest point of the shadow reads 5/1/25/48
It's put on top of a blue circle and the circle on top of the green backgrd.
The circle traps up until it gets close to the shadow then it stops.
Any ideas?
Thres holds?

If the shadow was created as an effect in Photoshop/Illustrator/InDesign make sure that the transparency setting is set to multiply for the shadow. This will cause it to overprint when it gets converted to PDF (flattened). If you do not have native files for the job you should either acquire them or ask the customer to validate all shadows being set to multiply.

Prinery process plan

1st Refine
In Color convert,
Uncheck Set colors to knockout
And check Set black to overprint

Set your 2nd Map colors Trap
the exact same way

Good Luck
