256 Chapter 25:
Solving Printing and Registration Problems
To apply overlap or overprint to a stroke
1 Apply a stroke to a filled object and select the stroke.
2 Open the Stroke toolbar in the Toolbox toolbar.
3 Click the Overlap button
or
Click the Overprint button.
Tip: An alternate method of overlap or overprint with a stroke is to assign it while applying the
stroke in the Assign Colors dialog box. Click Stroke toolbar > Assign Colors > Stroke tab and
turn on Overlap or Overprint in the Print Attributes group box.
Removing overlaps and overprints
Overlap and overprint are off when shapes are created. When overlap or overprint is turned off,
one shape does not print over another. After applying an overlap or overprint you can remove
it and return to butted objects.
In this example, the light shape prints as shown and the dark shape prints entirely. The two
shapes are butted together (which has the potential for registration problems but avoids
creating a Spectratone color in the overlap/overprint area).
To remove overlaps and overprints from fills and strokes
1 Select the overlap/print object.
2 Open the Fill or Stroke toolbar in the Toolbox toolbar.
3 Click the Overlap/Overprint off button.
Tip: An alternate method of removing overlap or overprint with a stroke is to remove it in the
Assign Colors dialog box. Click Stroke toolbar > Assign Colors > Stroke tab and turn off
Overlap/print in the Print Attributes group box.
Assigning a stroke to an object
Because a stroke prints directly over a shape's cutline, half the stroke is inside the cutline and
half is outside. The stroke has the effect of reducing the area of the shape inside the cutline
while expanding the size of the shape outside the cutline as determined by the width of the
stroke. The Behind Fill print attribute in the Stroke tab of the Assign Colors dialog box can be
used in two ways to solve registration problems.
