Abstract: An embodiment implements a methodology for printing non-saturated text and lines in a way that removes the jagged edge problem. An embodiment uses a combination of two screens, e.g. AM screening and applying pure color. For example, according to the embodiment, the closer to the edge from the interior of text or lines, the less amplitude modulation half toning is applied and the more actual color or contone is applied. A particular algorithm for determining and using a blending parameter is provided.
