A method and system are proposed in which a moving window based operator is applied to a page of a PDL document that has been decomposed, and the objects within the page flattened and rasterized. The window moves along the raster scan line, and processes rasterized data within the window, detecting any color-to-white or white-to-color interface (edge). The white rasterized portion is then dilated outward across the interface into the color portion, the dilated amount being based on a size of a reverse fine line and/or small text font character to be reproduced. A size of the fine line and/or small text font object is determined and if below a threshold, object dilation may be given effect. A dilation amount may increase as the object size decreases until the size reaches a lower threshold at and beyond which a maximum dilation amount may be applied.
