default trapping for Print layouts.
Select a Trapping Method:
• Click Absolute to trap using the values in the Auto Amount and Indeterminate fields
according to the object and background colors involved. If the object color is darker, the
object is choked by the background using the Auto Amount value. If the object color is
lighter, the object is spread into the background using the Auto Amount value.
• Click Proportional to trap using the value in the Auto Amount field multiplied by the
difference between the luminance (lightness or brightness) of the object color and the
background color.
• Click Knockout All to turn off trapping and print objects with a zero trap amount.
• Check Process Trapping to trap each process separation plate individually when a page
contains overlapping process colors.
• Check Ignore White to specify that an object color in front of multiple background colors
(including white) does not take white into account when trapping.
Enter a trapping value in the Auto Amount field or choose Overprint:
• Enter a value in the Auto Amount field to control the amount of trapping that QuarkXPress
applies to object and background colors that have an Auto Amount specified in the Trap
Specifications dialog box (Edit > Colors > Edit Trap), and to control the amount of
trapping applied to items with an Auto Amount (+) Trap Information or (–) specified
in the Trap Information palette (Window > Trap Information).
• Choose Overprint to cause overprinting for object and background colors with an Auto
Amount specified in the Trap Specifications dialog box (Edit > Colors > Edit Trap), as
well as for items with an Auto Amount (+) or (–) specified in the Trap Information palette
(Window > Trap Information).
