Question regarding lockout using spot colours

[danno531]

Hi All, Hop eyou guys can help me find a solution to this.

Im creating a 3 - 4 spot colour skateboard deck that the client wanst to show the wood grain of the deck through the design. I can successfully kockout part of teh design, however when I duplicate teh design to sit above and behind the previous layer the knockout will not work.

Ive attached an image with red circles to show where im hitting an issue. If anyone could shed any light on this it would be greatly appreciated.

Try if Object > Live Paint helps (try it on a copy).

Try removing the Multipy effect from the flowers, then make one group of all of them, and apply it again.

Two groups, each with effect appliedOne group with effect applied

How *is* it set up at the moment?

This cries for a knockout group.
