Color Settings
The
Color Settings
area lets you override some of the global settings
by entering values for individual colors.
Ink Set
Specifies color settings for ink sets.
Select an ink set in the list. The neutral densities for the process
colors change to those specified by the ink set.
Neutral Density
Specifies the neutral density value for each process color.
Step Limit
Determines whether a trap will be generated between adjacent
colors (objects) depending on the relative difference (in %) in
their amounts of colorants (inks). If the relative difference in
amounts of colorants between two objects is less than the
relative step limit specified, then no traps are generated.
A setting of 0 removes
Step Limit
as a criteria for trapping. A
setting of 100 disables trapping.
Range: 0 to 100%
There is also an absolute threshold of 5% to prevent traps
between very light colors. See
Minimum Absolute Step Limit
.
Trap Color Scaling
Lightens the intensity of the trap color for a particular
separation.
Trap color scaling helps to make traps in sensitive trapping
situations less noticeable, for example, when trapping pastels.
Scaling reduces the visibility of traps by reducing the amount of
each component ink relative to its contribution to the trap color.
The system applies the
Trap Color Scaling
value to the
separation values of the trap that originates from the lighter
color (when neutral densities are compared).
A setting of 0 makes the traps invisible because all separations
of the trap color become equal to the darker color. A setting of
100 switches off
Trap Color Scaling
.
