Abstract: The method generates trapping contours on color edges in a page to be printed that is defined in digital data. The trapping contours reduce the defects that are caused by register errors in the printing machine. The method operates similarly to a filter, using a window that is moved over the entire page, picture element by picture element. Certain neighboring picture elements of the central element are selected and used for calculating a trapping color. The color separation proportions of the central picture element are compared with the corresponding color separation proportions of the trapping color. The result of the comparison determines which color separation proportions of the central picture element are to be changed.
