4 To create a trap when knocking out the underlying color, choose Select > Modify > Expand or Contract, depending

on whether the overlapping spot color is darker or lighter than the spot color beneath it. In the Channels panel,

select the underlying spot channel that contains the areas you want to knock out. Press Backspace (Windows) or

Delete (Mac

OS).

This method can be used to knock out areas from any channels under a spot color, such as the CMYK channels.

5 If a spot color in one channel overlaps more than one other spot color, repeat this process for each channel that

contains the areas you want removed.
