Manually overprinting strokes or fills
You can overprint strokes or fills of any selected paths using the Attributes palette. An
overprinted stroke or fill doesn’t need to be trapped, because overprinting covers any
potential gaps between adjacent colors. You can also overprint a stroke to simulate a trap
(by overprinting a color you’ve manually calculated as the proper combination of two
adjacent colors).
Keep the following guidelines in mind as you apply manual overprinting:
•
If you use the Overprint Fill option on a 100% black stroke or fill, the black ink may not
be opaque enough to prevent the underlying ink colors from showing through. To
eliminate the show-through problem, use a four-color (rich) black instead of a 100%
black. Consult with your service provider about the exact percentages of color to add to
the black.
•
When using a stroke to trap objects (but not text characters), select a stroke weight that
is twice the required trap width. This is because the stroke is applied to the center of its
path, so you are overprinting only half of the stroke width beyond the object’s
boundary.
•
When using a stroke to trap two spot colors or a spot and a process color, you usually
apply the lighter color to the stroke, and overprint the stroke.
To overprint a stroke or fill:
1
Select one or more paths with the selection tool or direct-selection tool , or select
text characters with the type tool . To overprint the stroke of a path that is pasted inside
a frame, you must first select the nested (inner) path using the direct-selection tool.
