摘要：
A computer-implemented method traps an edge in a color page described by page data, independently of the output device. The method comprises identifying, based on page data for a color page, an edge and first and second adjacent regions having the edge as a common boundary. defining a clip region, including the edge and at least part of one of the first and the second regions, and generating and storing device-independent trap data representing the clip region for use by an unspecified output device for trapping the edge. A page trapped by the method for output on an unspecified output device includes trap data for at least one edge represented in the page, the trap data for each edge comprising edge data, defining the edge, adjacent region data, describing a first and a second adjacent region sharing the edge as a common boundary, and clip region data, defining a clip region including the edge and at least part of the first or the second adjacent regions.
