Adjust overlapping spot colors
To prevent overlapping spot colors from either printing over or knocking out the underlying spot color, remove one of the spot colors where they overlap.
Use a printed sample of the overprinted inks to adjust your screen display to help you predict how colors will look when printed.
Note: In
some cases, such as when you use varnish and bump plates, you may
want colors to overprint.
- Choose Select > Load Selection.
To
quickly select an image in a channel, hold down Ctrl (Windows) or
Command (Mac OS), and click the channel in the Channels palette. -
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
palette, 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.
