3 Color Joins
Determines the shape of a trap where three or more objects
meet. You can select one of the following shapes:
Mitered Corners
Clipped Chokes
Trap Trimming
Reduces the size and shape of traps that extend into small
objects.
Where a regular trap can get too close to another object such
as white knockout text, the trap is trimmed back to the center
point of the object that is accepting the trap. This can result in a
trap with a variable width along its length.
In the
Trap Trimming
box, select
Automatic
to have the trap
trimming feature re-examine any traps created in this job and
reduce them as needed.
Note: This option is available only with the
Advanced Trapping
option.
Cutbacks
Create Cutbacks
Select to create a trap where multi-colored objects border with
white areas of the page. This prevents mis-registration artifacts
from being visible along white edges and helps keep knockout
(reversed) text from filling in.
Create Cutbacks when Primary tint value is above
Determines the minimum primary tint value at which cutbacks
should be created.
Create Cutbacks when Primary ink Neutral Density is above
Determines the minimum primary ink neutral density value at
which cutbacks should be created.
Cutbacks width percentage of global traps
Determines relative width of global traps that should be taken
up by the cutbacks.
