摘要： Methods and apparatus implementing a technique for forming a trap polygon which does not interfere with the print quality of other trap polygons or objects. Edges in close proximity to a color transition edge (“CTE”) are checked for potential interference. A trap polygon is formed for the CTE that avoids any interfering edges or trap polygons for those edges. The technique can be applied to form a trap polygon for each edge in a page to be printed. In general, in one aspect, forming a trap polygon for trapping a color transition edge, where the trap polygon has an associated trap color determined by colors defining the color transition edge, includes: identifying one or more potentially interfering edges which intersect a keep away zone defined by the color transition edge; screening the potentially interfering edges to identify interfering edges which are part of an object which is of a significantly different color than the trap color; and forming a trap polygon for trapping the color transition edge including shaping the trap polygon to avoid overlapping objects and any trap polygons corresponding to any interfering edges.

摘要： Methods, program products and systems for automatically trapping drop shadows. For at least one segment incident to an atomic region which includes a drop shadow, and for each side of the segment, determining a first flattened color of the side's incident atomic region, and if the atomic region includes a drop shadow, additionally determining a second flattened color omitting the color of the drop shadow. An effective neutral density from the side's first flattened color is determined and, if the side has a second flattened color, the side's second flattened color. The two atomic regions incident to the segment are trapped based upon the effective neutral densities for the respective sides.
