Separations
When trapping linework layers the program automatically determines
the color separations which are spread or choked. However, you can
prevent a color separation from being modified by unchecking the corresponding
check box. The check boxes indicate the color separations
which are allowed to be spread or choked. Click ALL to allow the program
to modify all four separations.
Trapping area
Specify the size of the trap area using the slider or input box. The color
separations automatically determined by the program are increased
(spread) or decreased (choked) by the specified size, according to the
trapping mode.
Note:
The trap area should not be wider than the thinnest line on the layout.
Mode
A linework layer can be trapped in two ways:
• Inside the linework
• Against other layers
Trapping Inside the Linework
The individual linework color areas are trapped against each other. This
is done fully automatically. The program determines the color separations
and decides whether to enlarge (spread) or reduce (choke) them.
