A method of improving edge rendering of objects includes dilation (or contraction) of an object's tag plane by one or more pixels into the surrounding region, with the adjacent tag region having a corresponding contraction (or dilation). The objects of interest (e.g., white text) are first identified; the corresponding object tag plane is then spread or choked, in a fashion analogous to trapping. In the case of negative text on a tint background, by expanding the tag plane for the negative text object, the text hint would be forced one pixel into the tint object plane everywhere along the perimeter of the negative text. This could then enable greatly improved negative text rendering.
