Trapping
Trapping Individual Layers Manually
http://www.image2output.com
The parameters controlling this mechanism are defined in the trapping
profile named STANDARD. See below for details on how to view these parameters.
Trapping Against Other Layers
Linework is also trapped against other layers located below it. These layers
are referred to as ‘CT’ here. Choose one of the following options to
determine the way this is done:
• LW ONLY
No trapping against other layers, only trapping inside the linework.
• LW CT
Linework spreads into other layers. Certain LW color separations are
enlarged by the size of the trap area.
• LW CT, color dependent
The program automatically determines the best method (spread or
choke) on the assumption that all layers located below the linework
consist of the same color. The assumed color is also used for the
other options to decide whether trapping is required at all.
This color is defined in the STANDARD trapping profile under the name
CT BACKGROUND COLOR. See below for details on how to view the settings
of this profile.
