FlightCheck Trapping Frame/Line

All Trapping settings under Frame/Line deal with the color of a frame or a line. Frames can only be found on text or image containers whereas lines exist as separate objects.

Overprint – This Ground Control will trigger if a frame or line color is set to overprint. Setting frames and lines to overprint may cause them to blend into the background and disappear.

Knockout – This Ground Control will trigger if a frame or line color is set to knockout. Setting frames and lines to knockout may allow the paper to show through in areas where you are expecting color to appear.

Auto – In Quark, you can set a default value in the Preferences for Auto Amount. By default, this value is 0.144 points. Whatever the value you set, the Ground Control will trigger if a color used in a frame or a line is set to either Auto Amount (+) or Auto Amount (-).

Custom – This Ground Control will trigger if the color used in a frame or line has been set to Custom.
