Range: 1% to 100%
Default: 25.0%
Minimum Absolute Step Limit
Determines that no traps will be generated between adjacent
colors (objects) if the absolute difference in the amount of
colorants between two objects is less than the absolute step
limit.
This limit is intended to prevent traps between very light colors
or colors with very small color steps as found in blends. For a
trap to occur, the difference between amounts of colorants
(separations) must be greater than this
Minimum Absolute
Step Limit
and the value set for the relative step limit.
Range: 1% to 100%
Default: 5.0%
Common Density Limit
Determines whether a trap will be generated between adjacent
objects that have common colors. If the two objects have
enough common color, a trap is not required.
If a color is to be trapped based on the
Step Limit
value, the
neutral density of the shared color is calculated and compared
to the
Common Density Limit
value. If the shared neutral
density is greater than the limit, no trapping occurs.
A setting of 3.294 is approximately equivalent to the sum of
100% of each of the CMYK inks. A trap is always created if you
type a value greater than or equal to 3.294.
Range: 0.001 to 10.0
Default: 0.5
Centerline Trap Limit
Determines whether centerline traps are created between
objects with similar values for neutral density. The system
compares the neutral densities of two adjacent colors and
creates a centerline trap when the neutral density of the lighter
area is greater than the neutral density of the darker area
multiplied by the
Centerline Trap Limit
value.
Note: You cannot add a centerline trap between black or opaque inks.
A setting of 0 results in almost all centerline traps. A setting of
100 results in no centerline traps unless adjacent objects have
exactly the same value for neutral density.
